| Abstract: | We examine how transmission congestion alters the environmental benefits provided by renewable generation. Using hourly data from the Texas and Mid-Continent electricity markets, we find that relaxing transmission constraints between the wind-rich areas and the demand centers of the respective markets conservatively increases the non-market value of wind by 31% for Texas and 13% for Mid-Continent markets. Much of this increase in the non-market value arises from a redistribution in where air quality improvements occur { when transmission is not constrained, wind offsets much more pollution from fossil fuel units located near highly populated demand centers. |

| Abstract: | Cattle stocking rate is a key decision in grazing management, influencing forage use, ecosystem resilience, and rangeland sustainability. This study investigates how drought conditions and hay availability affect stocking rates across the U.S. Using county-level panel data from 1982 to 2022, we estimate a fixed-effects model incorporating current and lagged drought indices, agroclimatic variables, and hay stocks. Results show that water deficits significantly reduce stocking rates, with effects persisting into the following year. Lower hay stocks are also associated with reduced stocking, indicating producers adjust stocking intensity in response to feed constraints. We project future stocking rates under CMIP6 climate scenarios (RCP 4.5 and 8.5) through 2099. Projections show gradual declines under RCP 4.5 and sustained reductions under RCP 8.5, especially after mid-century. These findings highlight the vulnerability of grazing systems to climate change and the need for adaptive management to maintain livestock productivity. |

| Abstract: | Nonpoint source pollution from agriculture is the leading cause of nutrient pollution in the US. This paper addresses whether localized, farmer-led programs can cost-effectively reduce nonpoint source pollution by increasing the adoption of agricultural conservation practices. We study this in the context of an innovative program in Wisconsin that incentivizes farmers to take collective leadership of improving water quality in their local watersheds. Using a shift-share instrumental variables design, we find that a 10 percentage point increase in farmer participation in these programs leads to a 0.03 mg/L reduction (14%) in ambient phosphorus concentrations in local streams and rivers. We also show that this change causes an increase in the adoption of cover crops, conservation tillage, and more diverse crop rotations. Importantly, this localized approach achieves water quality and conservation improvements at a substantially lower cost than existing federal subsidy programs, demonstrating the potential for bottom-up approaches to address nonpoint source pollution in other contexts. |

| Abstract: | Agricultural runoff significantly contributes to nutrient water pollution, leading to harmful environmental and economic consequences. Cover cropping (CC), the practice of planting non-cash crops during off-seasons, has emerged as a promising conservation strategy to mitigate these impacts. Payment for ecosystem services programs, such as the USDA’s Environmental Quality Incentives Program (EQIP), have increasingly supported CC adoption through incentives. This study evaluates the social value of EQIP in enhancing water quality by examining its impact on CC adoption and the subsequent reduction in water pollution in the Midwest. Leveraging a unique 17-year, satellite-derived dataset on plot-level CC adoption and granular harmonized water quality metrics, we find that a one percentage point increase in upstream CC adoption reduces total nitrogen in surface water by 0.9%. An event-study analysis of EQIP’s Mississippi River Basin Initiative shows an initial 8.7 percentage point increase in CC adoption, with the impact diminishing over time. Overall, EQIP’s CC practices recover 48% of their implementation costs through reductions in nitrogen pollution under conservative assumptions, suggesting partial but significant economic returns via water quality improvements. |

| Abstract: | Risk has always been central to agriculture, and climate change has amplified production challenges like droughts and heatwaves. While tools such as irrigation and federally subsidized crop insurance help manage uncertainty, the impact of crop insurance on water resource use under extreme heat remains underexplored. This study investigates how crop insurance participation affects irrigation water use, particularly under varying heat conditions. Using a county-level panel dataset from 2008–2020 that combines crop-specific irrigation, insurance, and weather data across the United States, we apply fixed-effects and instrumental variable approaches. Results show that higher crop insurance participation is associated with increased total irrigation water use, driven primarily by surface water. Groundwater use shows weaker and less consistent responses. Additionally, the effect of crop insurance on water use diminishes as heat intensity increases. Our findings reveal a trade-off between risk management and water sustainability, suggesting that integrating conservation incentives into crop insurance programs could help align climate risk mitigation with long-term resource goals. |

| Abstract: | Meat consumption is a major driver of global greenhouse gas emissions. While pricing interventions have shown potential to reduce meat intake, previous studies have focused on highly constrained environments with limited consumer choice. Here, we present the first large-scale field experiment to evaluate multiple pricing interventions in a real-world, competitive setting. Using a sequential crossover design with matched menus in a Swiss university campus, we systematically compared vegetarian-meal discounts (-2.5 CHF), meat surcharges (+2.5 CHF), and a combined scheme (-1.2 CHF=+1.2 CHF) across four campus cafeterias. Only the surcharge and combined interventions led to significant increases in vegetarian meal uptake--by 26.4% and 16.6%, respectively--and reduced CO2 emissions per meal by 7.4% and 11.3%, respectively. The surcharge, while effective, triggered a 12.3% drop in sales at intervention sites and a corresponding 14.9% increase in non-treated locations, hence causing a spillover effect that completely offset environmental gains. In contrast, the combined approach achieved meaningful emission reductions without significant effects on overall sales or revenue, making it both effective and economically viable. Notably, pricing interventions were equally effective for both vegetarian-leaning customers and habitual meat-eaters, stimulating change even within entrenched dietary habits. Our results show that balanced pricing strategies can reduce the carbon footprint of realistic food environments, but require coordinated implementation to maximize climate benefits and avoid unintended spillover effects. |

| Abstract: | We test for and measure green waste: the misallocation of public subsidies for green investment projects. Our context is a major Norwegian program for green investment subsidies. We develop a model of subsidy allocation and apply it to detailed project-level data on carbon emissions and subsidy amounts for both marginal and inframarginal projects. We find that decision-makers could have achieved the same level of emission reductions at less than half the cost. To isolate the sources of this green waste, we use data on both ex-ante expected and ex-post realized emission reductions for each project. We find that decision-makers are able ex-ante to identify the projects with the highest ex-post emission reductions but unwilling to select them. |

| Abstract: | A rapid transition to low-carbon production is essential for climate mitigation, but its economic costs and benefits are not evenly shared. This paper studies how carbon pricing affects workers of different skills when clean and dirty energy sectors differ in their skill intensity. We extend a dynamic multi-sector environmental growth model in the spirit of Golosov et al. (2014) by introducing high- and low-skill households and a production structure in which clean energy is relatively high-skill intensive and dirty energy relatively low-skill intensive. We show that a Pigouvian carbon tax decentralizes the first-best allocation by internalizing the external cost of emissions, yet it is not distributionally neutral: the induced reallocation of capital and labour toward clean production raises the skill premium and can reduce welfare for the low-skill household. Numerical simulations calibrated to the U.S. economy confirm that aggregate welfare gains coexist with significant welfare losses for low-skill households, raising concerns about the political acceptability of such policies. |

| Abstract: | Ecological economics is a transdisciplinary attempt to deal with complex non-linear systems of humans and nature, merging aspects of economics, environmental economics, ecology and environmental studies, among others knowledge fields. This paper introduces some of the concepts of this field initially describing the Anthropocene and planet boundaries, the impossibility of continuous economic growth, the necessity of decreasing inequality levels, failures of market allocation, and human nature and well-being. Besides, the paper illustrates policies addressing sustainable scale, inequality levels and problems of market allocation having as background the Brazilian reality. In addition, the paper presents a pluralistic perspective of ecological economics, including some ongoing debates among prominent researchers in the field. Hence, this paper proposes to be a didactic introduction of ecological economics illustrated with applications from Global South. |

| Abstract: | This paper investigates the relationship between female leadership and firms’ environmental performance using data on 15, 612 firms across 32 countries in Europe, Central Asia, and MENA from the World Bank Enterprise Surveys. Environmental performance is measured through the Firm Environmental Performance Index (FEPI). The instrumental variable approach results show that female leadership significantly improves environmental performance and green practices such as CO₂ monitoring, environmental certifications, and energy management. A one-standard-deviation increase in female leadership raises FEPI by 11 percent, particularly in smaller and low-technology firms. Therefore, policies promoting women leadership could help to mitigate the consequences of climate change. |

| Abstract: | We analyse the distribution of emissions and other environmental pressures embedded in house-hold consumption across the EU. For this purpose, we extend the microsimulation model EUROMOD with environmental data from an input-output database to estimate environmental footprints em-bedded in household consumption associated with emissions like nitrogen and particulate matter, as well as other environmental pressures, like water and energy footprints. We then assess the distri-bution of these environmental footprints across different household characteristics like income, household type, urban density and others. We go into further detail by distinguishing environmental pressures by the stage along the value chain at which they occur, as well as by the consumption group they are associated with and by region. Our main finding is that all environmental pressures increase with income, but the extent to which they increase depends crucially on the consumption category, the specific environmental pressure, households’ further socio-economic characteristics and other factors. We argue that accounting for these factors is key for designing fair and effective environmental policy. |

| Abstract: | We introduce two new instruments and use a 2SLS within estimator to quantify the role of income and policy in reducing nitrogen pollution in waterbodies. We instrument county income with a shift-share measure and county Environmental Quality Incentive Program (EQIP) investment for water quality-related practices, using an instrument constructed from EQIP practices that are orthogonal to water management. Our results show EQIP investment reduces nitrogen concentrations in waterbodies with an elasticity of - 0.0159, which is statistically significant at the 5% level. We further find a quadratic-shaped relationship between income and nitrogen concentration, with a peak at a natural log per capita county income of $37, 798, slightly below the sample mean of $39, 735. For counties with above-average incomes, an increase in local income is associated with a decrease in water nitrogen levels, likely due to the community's ability and additional resources to manage and mitigate the impact of local production on water resources. |

| Abstract: | Motivated by the growing attention and concerns surrounding climate change and the potential role of institutional investors' ownership concentration (OC) in reducing corporations' greenhouse gas (GHG) emissions, this article explores the relationship between various forms of institutional ownership and firms' GHG emission intensity. To do so, the authors employ an extensive dataset of 628 European‐listed corporations with observations from 2015 to 2022. This manuscript method consists of linear regression models. This study's empirical results underline the positive and significant effect financial institutions, pension funds, governments, and foreign institutional investors' OC have on companies' GHG emissions. On the other hand, the regression models present empirical evidence suggesting a negative and significant effect between cross holdings OC and firms' GHG emissions. Finally, the authors identify a negative and non‐significant relationship between "other" institutional investors and organizations' GHG emissions. These findings are robust since the authors have conducted several regression analyses with different approaches and have addressed potential endogeneity bias. The present article makes significant contributions to the scholarly literature and regulatory practice underlying the active role corporate governance and institutional investors have in supporting a carbon‐neutral future. |

| Abstract: | This work explores the potential cover crops and no-till adoption in the United States under four policy designs using a highly stylized economic model. Farmers who will adopt these conservation practices may receive cost-share payment from the federal conservation program and carbon payment from a voluntary private carbon initiative. To limit the number of acres receiving the cost-share payment from the Environmental Quality Incentives Program (EQIP), two types of limitations to EQIP participation (HEL and budget limits) and two different types of additionality requirements (financial and physical) are imposed in the simulated models. Four scenarios include four policy designs: (1) full additionality required; (2) physical additionality required and unrestricted EQIP payments; (3) physical additionality required and HEL-limited EQIP payments; and (4) physical additionality required and budget-limited EQIP payments under reverse auction in HEL-acres. The results show that the estimated adoption rates are highest in scenario 2 (cover crops: 34% of total cropland, no-till: 69%) and lowest in scenario 1 (cover crops: 2%, no-till: 25%). Imposing restrictions on EQIP participation can reduce the adoption of conservation practices to 6%–11% for cover crops and 28%–34% for no-till, but EQIP spending has become more cost-effective in terms of cost per ton of greenhouse gas emissions reduction. |

| Abstract: | Households are negatively affected by water outages under the context of more frequent natural disasters, aging water infrastructure, and inadequate investment in upgrading the system. Using choice experiment data and random coefficient model, we estimated Kansas households’ willingness to pay (WTP) to avoid water outages during extreme weather events. The results indicate that the WTP increases with the duration of the water outages at a decreasing rate. The WTP is also higher if the water outage occurred during winter. Furthermore, we find heterogeneous preferences of urban and rural households as the former care more about the time and season when water outages occurred. These findings provide important information and insight for policy makers when making investment decisions on hardening water infrastructure. |

| Abstract: | This paper examines how temperature changes affect household food-at-home spending in the United States using detailed transaction data from 2004 to 2020 and a unified framework that distinguishes between short-term weather shocks and long-term climate adjustments. We decompose temperature into climate norms (20-year moving averages) and weather shocks (deviations from norms) to estimate both immediate and long-term consumption responses. Results show that higher temperatures consistently reduce food-at-home spending, with a one-degree Celsius increase in temperature shock reducing weekly spending by $0.04 and an equivalent increase in long-term climate norms reducing spending by $0.09. Using Heating and Cooling Degree Days, we find asymmetric effects: cold conditions increase food-at-home spending while hot conditions reduce it. These patterns likely reflect changes in food preservation needs, shopping frequency, and meal preparation behavior in response to temperature variations. |

| Abstract: | Extreme temperatures threaten agriculture and exacerbate global food insecurity, yet their direct impact on dietary choices remains poorly understood. We provide novel evidence of how short-term exposures to extreme temperatures affect macronutrient intake in China. We show that both hot and cold weather elevate high-fat diet risks. In particular, hot weather reduces carbohydrate and protein consumption but not fat intake, while cold weather increases all nutrient intake, particularly fats. Temperature-induced dietary changes are shaped primarily by physiological responses to thermal stress, whereas physical activities demonstrate little effect. Technologies that improve indoor thermal comfort (via fans, air conditioners, and heating systems) substantially mitigate high-fat diet risks. Socioeconomic disparities are evident, with rural and poor individuals more likely to adopt high-fat diets under hot or cold weather. Projections indicate that more extreme temperatures due to climate change may increase the prevalence of high-fat diets nationally, while substantial regional heterogeneity emerges, with declines in northeast China and increases in southern China. These results highlight a crucial but overlooked pathway linking climate change to dietary health inequality. |

| Abstract: | Historically, financial risk management has mostly addressed risk factors that arise from the financial environment. Climate risks present a novel and significant challenge for companies and financial markets. Investors aiming for avoidance of firms with high carbon footprints require suitable risk measures and portfolio management strategies. This paper presents the construction of decarbonized indices for tracking the S \& P-500 index of the U.S. stock market, as well as the Indian index NIFTY-50, employing two distinct methodologies and study their performances. These decarbonized indices optimize the portfolio weights by minimizing the mean-VaR and mean-ES and seek to reduce the risk of significant financial losses while still pursuing decarbonization goals. Investors can thereby find a balance between financial performance and environmental responsibilities. Ensuring transparency in the development of these indices will encourage the excluded and under-weighted asset companies to lower their carbon footprints through appropriate action plans. For long-term passive investors, these indices may present a more favourable option than green stocks. |

| Abstract: | The current "multi-crisis" is not a set of separate shocks but a tightly interconnected system of climate and biodiversity pressures, food-energy-water insecurity, macroeconomic fragility, widening inequalities, rapid urbanization, and geopolitical stress. While the SDGs provide an integrated blueprint for action, progress remains insufficient, pointing to a persistent gap between global ambition and operational delivery. This study argues that closing this gap requires a practical Global Commons for implementation, one that can translate policy choices and investments into measurable outcomes, account for cross-sector feedbacks, and support locally feasible pathways. We present the Global Climate Hub (GCH), an AE4RIA-SDSN anchored initiative that combines physical and socio-economic modelling with policy-relevant modelling and participatory co-design. The GCH methodology is organized in three stages: (i) continuous SDG measurement through harmonized data pipelines, spatial diagnostics, and digital twins; (ii) co-designed transformation pathways generated through living labs and coupled model chains (energy, land use, water risk, transport, health, and beyond-GDP welfare and trade outcomes) to quantify synergies, trade-offs, and distributional effects; and (iii) financing, equity, and capacity-building mechanisms that connect pathways to investable roadmaps and strengthen the skills required for sustained implementation. By integrating quantification with stakeholder ownership and open decision-support tools, the GCH positions modelling as a practical instrument for policy prototyping, learning, and course correction. The approach is directly relevant to the evidence mandate of the 2027 Global Sustainable Development Report, offering a pathway-oriented basis for accelerating SDG implementation to 2030 and informing longer-term transformation beyond it. |

| Abstract: | Phosphorus (P) runoff from agriculture is a major driver of eutrophication in trans-boundary water systems like Lake Erie. This paper develops a dynamic game model to examine how strategic interactions between the U.S. and Canada shape long-term crop production and environmental outcomes under stochastic soil P dynamics. The results show that while unilateral decisions often lead to higher crop production, they also result in greater environmental damage due to excessive P runoff. In contrast, incorporating transboundary nutrient spillovers naturally reduces P application and mitigates environmental harm, though at the cost of lower production. These findings suggest the importance of integrating biophysical feedback and economic incentives in nutrient management, emphasizing that long-term sustainability requires balancing productivity with environmental constraints. |

| Abstract: | As renewable energy development accelerates, wind turbines are increasingly being installed on agricultural land, raising questions about their effects on crop production. This paper investigates the impact of wind turbine installations on agricultural productivity using a high-resolution dataset that combines parcel-level corn yield data with detailed information on wind turbine locations and weather characteristics. Using Difference-in-differences approach to address potential endogeneity, we find that parcels within an 8-kilometer radius of wind turbines experienced, on average, a 1% increase in corn yield after installation. These results suggest that localized microclimatic changes induced by turbines may improve growing conditions. Our findings highlight an overlooked positive externality of renewable energy infrastructure and underscore the importance of incorporating land-use interactions into energy policy and planning. |

| Abstract: | Antarctic krill ( Euphausia superba ) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Climate change is threatening krill populations and their predators, while current catch limits do not take into account climate variability or krill population dynamics. In 2024, CCAMLR was unable to renew its spatial catch limits, highlighting the urgent need for improved management of the krill fishery to prevent any harm to the Southern Ocean ecosystem. To address this, we propose a management framework that integrates variability in krill recruitment and key pathways between spawning and nursery areas—a krill stock hypothesis—to inform decisions on catch limits and conservation measures. Implementing this approach will require targeted data collection, which we propose can be achieved through a multisector collaborative network that combines traditional and new technologies, including the use of fishing vessels as data collection platforms. We use case studies to demonstrate how fisheries can contribute to data collection while promoting sustainable management. A major challenge in this effort is securing long-term funding for data collection, which is critical for managing climate-sensitive populations of high commercial interest. We therefore recommend using the industry as a source of funding, research platform and data provider, alongside national research funding opportunities. Given the fundamental role of krill in the Southern Ocean ecosystem, its decline would have cascading effects on predators and essential ecosystem services. |

| Abstract: | This study empirically analyzes the impact of livestock and poultry restriction policy on corn production, based on county-level data from China spanning the years 2000 to 2021. Utilizing a multi-period difference-in-differences model, the research also explores the policy's effects on water environment quality. The findings indicate that while the policy has had some success in reducing the emission of acidic substances and raising water pH levels, its overall effectiveness in improving water quality remains limited. Conversely, the policy has led to a 6.8% reduction in corn planting area and a 5.7% decrease in total corn production. Notably, the impact on corn production is more pronounced in regions designated for moderate pig farming development and in counties not primarily engaged in livestock farming. Overall, the policy achieves relatively modest environmental benefits at a substantial economic cost. This study provides valuable insights and empirical evidence on balancing rural environmental protection with ensuring food supply, thereby reinforcing China's food security. |

| Abstract: | Environmental issues have become important in trade agreement negotiations. NAFTA explicitly includes environmental provisions and they are affecting ongoing WTO and FTAA negotiations. The final role of the environment in the FTAA is uncertain, given opposition by most of the members. The draft FTTA agreement does not contain a separate section on the environment, but a US position paper indicates that environmental provisions are important and that US negotiators will seek to incorporate environmental concerns into specific chapters such those on investment and agriculture. The large number and varied economic and environmental conditions of the several countries in the FTAA, will make it difficult to include meaningful environmental provisions in the agreement, but environmentalists are seeking and the inclusion of such provisions in the NAFTA and WTO agreements will tend to make it difficult to get approval of future agreements that do not address environmental issues or at least that do not guard against creating pollution havens or that encourage laxness in environmental protection. This paper examines environmental and trade issues in the context of the FTAA negotiations including analyses of environmental conditions in the region and the pros and cons of their inclusion in the FTAA and other trade agreements. |

| Abstract: | The Ecodesign for Sustainable Products Regulation (ESPR), which aims to improve the environmental sustainability and circularity of products in the European market, entered into force in 2024. The objective of this report is to develop methods for defining classes of performance and the content of the future ESPR label. The report outlines a multi-step approach to select relevant product aspects and parameters appropriate for classes of performance, propose a method to develop classes of environmental performance based on the Product Environmental Footprint (PEF) single score and the single impact category, and develop classes of performance for circularity aspects/parameters. Additionally, the report discusses the potential impacts of establishing classes of circularity and technical performances and the interaction of the ESPR label with other labels and the Digital Product Passport (DPP). The report also proposes a typology of information to be included in ESPR labels, ensuring that the labels effectively communicate the environmental sustainability and circularity of products to consumers and other economic actors. The methods developed aim to provide guidance for ongoing and future preparatory studies, supporting the ESPR's objective of improving the environmental sustainability and circularity of products on the European market. |

| Abstract: | The relationship between climate disasters and substance use harms has been understudied. This study employs a mixed methods research design to assess the impact of severe floods on overdose deaths and identify relevant mechanisms driving this relationship. Drawing on opioid overdose death data from NCHS, presidential disaster declarations from FEMA, and severe storm event data from NOAA, we find severe floods in rural Appalachia led to a significant increase in county-level overdose death rates that persists for a decade post-flood. We then collected retrospective qualitative data from 17 stakeholders regarding the floods that occurred in Eastern Kentucky in July 2022. Interviews suggest this increase is perpetuated by decreased access to treatment, recovery, and harm reduction services; increased trauma; increased instability; and persistent stigma around help-seeking. Due to the predicted continuation of these disasters, understanding their impact on substance use harms is essential to mitigating future damage. |

| Abstract: | Food waste contributes substantially to methane emissions, and diverting it from landfills yields significant environmental benefits. This study examines the impact of residential curbside organics diversion programs, which redirect food waste from landfills to composting, on household food purchases. Using NielsenIQ Consumer Panel Data and a difference in-differences framework, we find that voluntary programs increase monthly household food expenditures by $3, while mandatory programs that require residents to separate organics lead to an additional $5 increase. The total effect of $8 under mandatory programs represents 8.2% of average monthly food spending. These results indicate a notable rebound effect: while diversion programs reduce landfill emissions, the unintended increase in food demand leads to an estimated $26 billion rise in food loss and waste nationwide and nearly $714 million in additional greenhouse gas damages. The findings highlight the need to account for behavioral responses in environmental policy design. |

| Abstract: | One of the salient aspects of climate change is the increment of both the intensity and frequency of natural disasters. This paper addresses how these factors interplay at a local level, focusing on Chilean regions at a quarterly basis for the period 2009-2025, using the local projections method. Results suggest that on average, a 1% shock in natural disasters' intensity has an immediate negative effect in employment by 0.06%, and an immediate negative effect on the debt market, increasing the household debt by 0.1 p.p. Overall, my results suggest that a 1% shock in natural disasters' intensity has an immediate positive effect in real GDP by 0.02%, and a significant long-term negative effect on GDP by 0.05%, potentially showing signs of reallocation of a country's income. When analyzing natural disasters' frequency, estimates suggest that Chilean regions that suffer a natural disaster are more likely to experience short-term decreases in employment and increases in household debt, and lower GDP, although the latter effect is found to not be statistically significant. I rely on a panel VAR model to estimate the impact of natural disasters' intensity as robustness checks, and find that my original conclusions hold: natural disasters have a short-term negative effect on employment at 0.01% and a long-term negative effect on growth at 0.2%. |

| Abstract: | This paper examines how GATT/WTO membership has influenced agricultural virtual water trade (VWT), a crucial channel for reallocating global water resources through trade. Using a newly constructed dataset and a theory consistent gravity framework, we find that while GATT/WTO membership initially appears to increase VWT flows by 67.2 percent, this estimate falls to 22.8 percent once globalization effects are accounted for, with WTO-era membership driving the majority of the growth. Although multilateral liberalization has facilitated the redistribution of water from water-abundant to more water-scarce regions, it has also intensified sustainability concerns. VWT outflows from medium-scarcity exporters have surged by 81.6 percent, and unfair flows—those moving from water-scarce to water-abundant regions—have increased by 68.4 percent. General equilibrium simulations further reveal that institutional trade preferences have disproportionately supported unfair VWT flows, reinforcing environmental inequities embedded in global trade patterns. These findings highlight the dual role of multilateral trade institutions and underscore the importance of integrating enforceable environmental provisions into future agreements to promote sustainable and equitable water governance. |

| Abstract: | Fossil gas is sometimes presented as an enabler of variable solar and wind generation beyond 2050, despite being a primary source of greenhouse gas emissions from methane leakage and combustion. We find that balancing solar and wind generation with pumped hydro energy storage eliminates the need for fossil gas without incurring a cost penalty. However, many existing long-term electricity system plans are biased to rely on fossil gas due to using temporal aggregation methods that either heavily constrain storage cycling behaviour or lose track of the state-of-charge, failing to consider the potential of low-cost long-duration off-river pumped hydro, and ignoring the broad suite of near-optimal energy transition pathways. We show that a temporal aggregation method based on 'segmentation' (fitted chronology) closely resembles the full-series optimisation, captures long-duration storage behaviour (48- and 160-hour durations), and finds a near-optimal 100% renewable electricity solution. We develop a new electricity system model to rapidly evaluate millions of other near-optimal solutions, stressing the importance of modelling pumped hydro sites with a low energy volume cost ( |

| Abstract: | Understanding how climate change beliefs are shaped by social networks is critical for designing effective climate communication strategies, yet the degree of peer influence across spatial and political contexts remains insufficiently understood. This study examines the influence of peer counties on local climate change beliefs using a spatial autoregressive (SAR) model. We construct geographic, political, and economic peer networks at the county level and quantify the magnitude of peer effects. Results show that a 10% increase in climate change beliefs among peer counties is associated with a 4.2% to 9.2% increase in average beliefs within the focal county, depending on the network type. The geographic peer network exerts the strongest influence, with estimated effects ranging from 6.7% to 9.2%, followed by the political network, with effects between 4.2% and 7.5%. Counterfactual simulations reveal that targeting interventions at top key opinion leader (KOL) counties—those most connected in a network—is more effective than targeting counties with extreme belief levels or KOL counties with below-average beliefs. These findings provide actionable insights for policymakers seeking to promote climate belief formation and encourage climate-friendly behaviors through network-informed interventions. |

| Abstract: | This model presents results from an intertemporal hydro-economic optimization model of land use and water allocation in California’s Central Valley (CV). We assess potential competition for land use between traditional agricultural production, solar leasing, and agri-voltaics production methods that jointly produce crops and solar electricity on the same unit of land. We evaluate the extent to which setting aside agricultural land for solar generation or switching to agri-voltaics (AV) production methods can provide groundwater conservation benefits under a wide range of illustrative policy scenarios. We find that solar and AV can complement groudnwater conservation efforts in the CV at a local scale, but would require substantial land use change and investment to provide broad water conservation benefits across the region. Our results also highlight the potential for ”water leakage” from concentrated innvestments in solar and AV systems in lieu of traditional crop production as regional crop mix patterns could shift, leading to irrigation intensification in other regions and potentially exacerbating water management challenges. |

| Abstract: | The development of sustainable agriculture has highlighted the critical role of Payment for Ecosystem Services (PES) programs in addressing environmental challenges while supporting agricultural productivity. This paper examines the Northern Everglades Payment for Environmental Services Program (NE-PES) as a case study to derive insights for designing cost-effective and collaborative PES programs. The NE-PES program implemented a hybrid payment scheme that integrated action-based and results-based contracts, enhancing economic efficiency and accountability. Advanced monitoring technologies, such as hydrological modeling and remote sensing, support accurate verification of service delivery, fostering trust among diverse stakeholders. Despite its achievements, challenges such as scalability, integration of diverse ecosystem services, and stakeholder heterogeneity highlight the need for innovative approaches in program design and implementation. |

| Abstract: | Water is an essential but increasingly scarce resource, especially in the Western U.S., where climate change and institutional fragmentation make efficient water regulation challenging. Adjudication, a legal process to formalize and clarify water rights, has emerged as part of efforts to establish clearer and enforceable rights. Despite its potential economic and environmental benefits, empirical evidence of the impacts of water rights adjudication remain limited. In this paper, I examine the effects of irrigation water rights adjudication on agricultural land and rural home values in Idaho. Using a repeated sales sample and a newly compiled water rights dataset, I employ a hedonic pricing model to estimate capitalization effects of adjudicated appurtenant irrigation rights. The main findings how that adjudicated rights significantly increase land value. The treatment effect evaluated at the sample mean implies an increase in a parcel’s land value by $381 per acre. Moreover, adjudication effects are highly heterogeneous. Parcels with more senior or larger rights gain more from this process. In particular, downstream senior water users experience the largest benefits from adjudication. These findings suggest adjudication can enhance the market value of water but also introduce distributional concerns that should be carefully considered in the design of future water policies. |

| Abstract: | Antimicrobial resistance (AMR) poses a critical threat to global health, with environmental transmission pathways - pharmaceutical waste, wastewater effluents, agricultural runoff - increasingly recognised as significant yet inadequately governed. Despite international calls for One Health approaches integrating human, animal and environmental sectors, coordination across these domains remains weak, particularly for environmental dimensions. This paper examines why environmental integration lags in Kenya's AMR governance, despite sophisticated formal architecture that includes national and county coordination platforms (NASIC, CASICs), technical working groups and the One Health AMR Surveillance System (OHAMRS). We investigate two research questions: (i) What are the enablers and barriers to effective governance of interlinkages among human health, animal health and environmental sectors in mitigating AMR? (ii) What are the options for effectively integrating the environmental dimension into AMR governance? Drawing on polycentric governance theory, the Institutional Analysis and Development (IAD) framework and the concept of Networks of Adjacent Action Situations (NAAS), we analyse how authority, information and resources shape interactions among overlapping decision centres across constitutional, collective-choice and operational levels. Through 12 semi-structured interviews with government officials, fisheries officers and environmental regulators, supplemented by policy document analysis, we map six action situations spanning planning, resource allocation, surveillance, stewardship, wastewater treatment and regulation. Findings reveal that constitutional-choice rules create formal overlaps intended to foster coordination, yet systematic asymmetries in authority, information and resources perpetuate the marginalisation of environmental issues. Boundary and position rules concentrate agenda setting in health sectors; information rules exclude AMR parameters from environmental permits and inspections; payoff rules reward clinical outputs while environmental investments compete with higher priorities; and scope rules omit environmental accountability targets. These rule configurations attenuate feedback loops between environmental action situations and upstream planning, maintaining system stability but at sub-optimal performance for One Health objectives. We identify rule-focused interventions - mandating environmental representation with voting authority, embedding AMR parameters in regulatory instruments, institutionalising joint inspection protocols, ring-fencing environmental budgets, and establishing explicit environmental targets - that would realign coordination toward genuine environmental integration. |

| Abstract: | This paper examines the economic effects of the global energy transition and the large uncertainty surrounding future fossil fuel demand on countries in the Asia-Pacific region. Under the paper’s baseline, coal demand is expected to shrink by 15 percent by 2035, although depending on global policy ambition and technological uptake, the decline could be as large as 45 percent. Model simulations indicate that one-third of global coal capital stock and one-quarter of Asia-Pacific coal capital stock could become stranded if the speed of the transition is underestimated. By contrast, global natural gas faces both upside and downside risks: when energy policy targets coal alone, natural gas extraction benefits, prompting an 18 percent rise in capital stock, whereas a fuel-agnostic transition would reduce gas capital stock by 16 percent. Impacts differ across countries, with high-cost coal exporters facing early losses, low-cost producers potentially gaining market share, and some gas exporters benefiting under select scenarios. At the same time, new growth opportunities will emerge for countries with strong critical mineral endowments and green energy potential. |

| Abstract: | This article examines whether French convertible local currencies (CLCs) can operationalise strong sustainability. Drawing on a national survey (53 associations, 431 professionals, 786 users) and a case study of the Eusko, multivariate analysis shows that participatory governance—not territorial scope—is the key organisational predictor of ecological selectivity, including supplier screening and environmental charter adoption. Qualitative evidence clarifies that mixed commissions and collective reserve allocation embed sufficiency criteria in daily practice. However, mandatory one-to-one euro convertibility constrain aggregate impact by linking local money supply to national liquidity cycles and limiting public-sector use. The findings indicate that CLCs can foster sufficiency-oriented innovation where subsidiarity is matched by deliberative capacity, but broader systemic influence depends on regulatory reforms to expand fiscal subsidiarity and green refinancing options. The study contributes empirical evidence to debates on monetary plurality and sustainable provisioning. |

| Abstract: | Climate change is widely recognized as a driver of violent conflict, but its broader social effects remain less understood. Ignoring these dimensions risks a vicious cycle where climate policies might undermine socially just adaptation. Evidence is still limited on how climate shocks influence political participation, trust, or migration. This paper helps fill that gap by examining links between climate change, conflict, and social sustainability, with a focus on inclusion, resilience, cohesion, and legitimacy. Using secondary data from 2019–24, the study applies simple correlation-based methods to test three hypotheses on the nature, severity, and composition of these associations. The analysis combines multiple climate impact measures, new conflict classifications, recent social sustainability frameworks, and controls for population and geography. The results reveal strong correlations—not causation—between climate events and contexts of fragility, conflict, and violence. Climate impacts are most pronounced in both national and subnational conflict settings. The study also finds robust links between fragility, conflict, and violence and low levels of social sustainability, reflecting its role as both a driver and consequence of conflict. Some dimensions—such as violent events and insecurity—appear weaker in areas most affected by climate shocks. Two of the hypotheses are supported, and one remains inconclusive. |

| Abstract: | We examine the impact of the European Union’s Sustainable Finance Disclosure Regulation (SFDR) on mutual fund flows and investment sustainability. The SFDR classifies funds into three categories to promote transparency and curb greenwashing: those with a sustainable investment objective (Article 9 or “dark green”), those that promote environmental characteristics (Article 8 or “light green”), and others (Article 6). Using a difference-in-differences design, we find that the SFDR had little effect on fund flows or portfolio sustainability. The disclosures were ineffective in part because they offered little new or clear information beyond what investors could already infer from fund names and mandates. In an experimental setting, we show that the current disclosures have minimal impact on investor decisions, but making the information more intuitive could improve the regulation’s effectiveness. |

| Abstract: | We evaluate Oregon households’ welfare gains from chainging the state’s marine-reserve system (MRS) by integrating carbon sequestration and coastal employment objectives. A D-efficient discrete-choice experiment (N = 371) varied reserve size, net jobs, blue-carbon and annual cost. Random-Parameter Logit models with Error-Component estimated in WTP-space yield stable welfare metrics and out-perform Generalized Mixed Logit models and utility-space analogues. All three attributes display positive, monotonic marginal WTP with blue carbon being the most valued. Scenario analysis shows strong loss aversion with an “optimistic” package (+50 % size, +200 jobs, +100 % carbon) commanding $465–704 yr⁻¹ in mean WTP, whereas equivalent contractions generate larger welfare losses. When budgets bind, respondents prioritize blue-carbon gains over job creation or additional reserve area, underscoring climate-mitigation benefits as the decisive driver of support. Preference heterogeneity by coastal use is pronounced: non-fishing recreationists exhibit the highest WTP, while recreational fishers value improvements less but demand greater compensation to accept the status quo. These findings indicate broad public backing for MRS policies that center on blue-carbon outcomes and suggest that tiered financing or carbon-credit mechanisms could secure stable funding while retaining stakeholder acceptance. |

| Abstract: | We show how investors with pro-environmental preferences and who penalize revelations of past environmental controversies impact corporate greenwashing practices. Through a dynamic equilibrium model, we characterize firms' optimal environmental communication, green investments, and greenwashing policies, and we explain the forces driving them. Notably, under a condition that we explicitly characterize, companies greenwash to inflate their environmental rating above their fundamental environmental value, with an effort and impact increasing with investors' proenvironmental preferences. However, investment decisions that penalize greenwashing, policies increasing transparency, and environment-related technological innovation contribute to mitigating corporate greenwashing. We provide empirical support for our results. |

| Abstract: | Understanding public support for energy policy is crucial for designing feasible interventions to mitigate climate change and reach net-zero goals. This is particularly the case given the increased salience surrounding energy policy in light of the major disruptions to global energy markets generated by the 2022 Russian invasion of Ukraine. Combining framing and conjoint experiments, I examine how framing and policy design shape public support for energy policy responses to this crisis in the UK. Results show that the public has strong preferences over specific policy features, supporting investment in renewables, reductions of energy imports from Russia and non-democracies, and policies that shield vulnerable groups. While security framing increases support for energy policy, its effect is smaller than that of policy design, and it has little impact on policy design preferences overall. The findings suggest that substantive policy designs remain crucial for generating public acceptance of energy policy, even in times of crisis. |

| Abstract: | This study conducts one of the first future-oriented assessments that privileges prospective life cycle assessment (LCA) and scenario-based social LCA to estimate the impacts of innovations, particularly those aimed at improving user experience and product appeal. The assessment examines various levels of environmental and social challenges while considering multiple technology implementation pathways, offering a comprehensive understanding of the implications of emerging technologies. The findings support the development of actionable strategies to manage these impacts effectively and provide stakeholders with critical information. By doing so, decisionmakers are better equipped to determine whether the added value of an innovation justifies its additional impacts. Since the added value of such innovations is usually excluded when defining the functional unit in LCA, we advocate for decision-making processes aligned with sustainability goals-whether at the corporate, national, or international level. To demonstrate this approach, photochromic fabrics are used as a case study. While these fabrics are estimated to cause +10% to+20% climate change impacts compared to conventional ones, these impacts can be reduced through strategies such as extending product lifespan, using recycled materials in production (-10%), and reducing the amount of photochromic dye required for functionality (-12%). Ultimately, the decision to commercialize such innovations should depend on their alignment with sustainability targets. |

| Abstract: | Finnish national climate and energy strategy sets the share of renewables in energy use to 38%, and a significant amount of this should be covered by biomass based energy. In 2020 forestry is set to contribute 24 TWh and agriculture 4-5 TWh to energy production. In particular, bioenergy resources are considerable in the rural areas. However, the regional aspects have gone without investigation before this study. This study is a general equilibrium analysis. We considered only the by-products and waste material from agriculture and forestry as the resources for bioenergy, and only heat and power production were considered as the potential end uses. A regional CGE-model (RegFinDynBio) was used to analyse the impact of increased use of bioenergy potential. Increase in bioenergy use will lower the levels of GDP and employment marginally but will, nevertheless, help to achieve the emission reduction goals. However, the regional results showed the uneven distribution of the costs. The regions that beforehand seemed to be the most promising ones fared the worst. Southern Ostrobothnia was the sole exception, because of its bioenergy export income. The greatest difficulties are seen in Kainuu. Eastern Uusimaa shows significant losses as well, but they can be traced back to the region’s economic structure, which is heavily dependent on fossil fuel refining industries. Some regions that use gas as energy source are seen to gain marginally because of their more diverse energy production system. |

| Abstract: | This research uses two life-cycle emissions models, GREET and IFSM, to establish benchmark values of the carbon intensity (CI) of corn and soybeans currently produced under producer conditions in three Northern Plains sub-regions. The benchmarks range from 0.24 to 0.42 lbs CO2e per lb of grain dry matter. CI benchmarks for rainfed crops are 8-18% higher than those estimated for comparable irrigated crops. The benchmark values are intended to be similar to results that a producer would likely obtain from employing either the GREET or the IFSM model for their own crops, when similarly adjusted to county-level circumstances. Effects of switching from conventional to reduced tillage are not yet well established, but as estimated by the current GREET model would reduce corn CI by as much as 19%, more for soybean CI. Switching from conventional tillage to no-till with a cover crop would reduce corn CI by around 90% for irrigated corn and well over 100% for rainfed corn. Comparable switching for soybeans would result in CI reductions of about 120% under irrigation and 150% for rainfed production. |

| Abstract: | Climate change poses serious risks to agricultural production, particularly for small-holder farmers who often have limited resources to adapt to changing conditions. This study evaluates the impacts of a bundled intervention—combining training and financial support—on the adoption of climate technologies and the resilience of smallholder farmers in Nepal. Leveraging exogenous variation in project roll-out resulting from administrative restructuring following the country’s new constitution, we show that the intervention increases the uptake of selected adaptation practices and improves household resilience. Adoption is associated with the timing of expected benefits and exposure to extreme weather, but not with demographic factors such as the gender or education level of household heads. These findings underscore the importance of climate adaptation practices in enhancing the resilience of vulnerable smallholders and highlight that adoption patterns vary by type and contextual relevance of the practice. |

| Abstract: | Climate change poses an increasing threat to global wheat production, yet the role of genetic diversity in shaping crop sensitivity to warming remains underexplored. This study examines varietal, seasonal, and spatial heterogeneity in U.S. winter wheat yield responses to climate stress using over 35, 000 variety-by-location observations from multi-environment trials (1962–2022). By linking trial data to high-resolution weather records and applying a linear mixed-effects model, we estimate genotype- and location-specific yield responses to seasonal temperature variation and extremes. Results show that spring heat and fall freezing are key drivers of yield loss, with spring heat alone reducing yields by an average of 13.5% per 10-unit increase in cumulative degree days above 34°C. Although the yield potential is positively associated with the first trial year of a variety, heat tolerance has not shown a corresponding improvement. Simulations suggest that warming beyond +2°C results in steep yield declines, particularly among heat-sensitive cultivars. These findings provide new empirical evidence on the distribution of heat resilience in the wheat gene pool and underscore the need to integrate heat tolerance into future breeding strategies. |

| Abstract: | This paper examines the relevance of banks’ exposure to climate transition risk in the interbank lending market. Using transaction-level data on repo agreements, we first establish that banks with higher exposure to transition risk face significantly higher borrowing costs. This premium is a combination of a risk premium, compensating lenders for increased credit risk, and an inconvenience premium, reflecting the sustainability preferences of key dealer banks. We also find that the transition risk premium intensifies during periods of financial stress, indicating that climate-induced risks amplify existing vulnerabilities in financial markets. Furthermore, the rate segmentation caused by transition risk premium has implications for the transmission of monetary policy. Transition risk is an important factor in financial stability and policy design. JEL Classification: Q54, G21, G32, Q58 |

| Abstract: | Rising AI electricity demand and persistent landfill methane emissions constitute coupled constraints on U.S. digital infrastructure and decarbonization. While China has achieved a rapid 'de-landfilling' transition through centralized coordination, the U.S. remains structurally 'locked in' to landfilling due to fragmented governance and carbon accounting incentives. This paper proposes a modular legacy landfill remediation framework to address these dual challenges within U.S. institutional constraints. By treating legacy sites as stock resources, the proposed system integrates excavation, screening, and behind-the-meter combined heat and power (CHP) to transform environmental liabilities into resilience assets. A system analysis of a representative AI corridor demonstrates that such modules can mitigate site-level methane by 60-70% and recover urban land, while supplying approximately 20 MW of firm, islandable power. Although contributing only approximately 5% of a hyperscale data center's bulk load, it provides critical microgrid resilience and black-start capability. We conclude that remediation-oriented waste-to-energy should be valued not as a substitute for bulk renewables, but as a strategic control volume for buffering critical loads against grid volatility while resolving long-term environmental liabilities. |

| Abstract: | Background: Adapting health systems for climate change can lessen the negative impact of climate change on human health. Even when not targeting climate-health links explicitly, broad health system strengthening interventions (HSSis) can ensure that the health workforce, infrastructure, and networks are robust enough to respond to and recover from climate-driven shocks. Objective: We explored the ability of an HSSi in a rural health district of southeastern Madagascar to serve as a climate change adaptation in response to Cyclone Batsirai in 2022. Method: We conducted interrupted time series analyses of eight indicators of infectious disease and health system performance to assess the impact of Batsirai on two zones of the HSSi. We then examined how traditional domains of HSS, such as physical and human resources, combined with less formal domains, such as collective values, influenced health system resilience during this time. Findings: We found that the majority of indicators were resilient to Cyclone Batsirai, with only vaccination rates affected in the two months following the cyclone, particularly in the zone where the HSSi had only begun eight months prior. Changes in long-term trends were rare, and, when observed, revealed a slight slowing of progress, but not a regression to historical levels. After re-establishing the road network and providing additional supplies through an emergency response, the health system was able to resume routine service delivery without further external input, and health system indicators continued to improve. The agility and responsiveness of the health workforce were enabled by formalized protocols, a culture of flexibility, open communication, and data-informed action. Conclusions: HSSis that are designed to encourage local adaptation may increase health systems' resilience to extreme weather events, resulting in health systems better adapted to climate change overall. |

| Abstract: | The aim of this report is to contribute to the development of the methodology for setting ecodesign requirements for sustainable products for the implementation of the Ecodesign for Sustainable Products Regulation (ESPR). Starting from the analysis of the Methodology for the Ecodesign of Energy-related Products (MEErP), used under the Ecodesign Directive (on energy-related products), and considering the extended scope of the ESPR, this report proposes indications for the identification of improved design options (DOs), as well as a methodology to assess, define and rank paths of DOs, taking into account their interactions. A more systemic definition of DO than the one provided in the MEErP is proposed, since it is recognised in literature that, to achieve optimal product sustainability, the focus should expand from the product to the system level (Schöggl et al., 2024). The identification of the DOs should be a multi-disciplinary activity, which considers technological, environmental and market-related aspects. The creation and validation of DO paths is supported by the use of Life-cycle Assessment. Moreover, the optimal design configuration for each path is identified by using life-cycle costing (LCC). Finally, the DOs are ranked applying societal LCC: factors for the monetisation of environmental externalities are proposed. Eventually the result should be complemented with considerations on social aspects and policy objectives. |

| Abstract: | Abstract In a global context marked by financial, social, and environmental crises, the search for alternative and sustainable financial models has become a pressing priority. This article provides a systematic review of the literature on Islamic finance to assess its contribution as an ethical and sustainable financial model. Through the analysis of 62 peer-reviewed articles published between 2010 and 2024, the study explores the foundations, instruments, areas of application, and limitations of Islamic finance in addressing contemporary global challenges. The methodological approach follows the PRISMA protocol, using a structured selection process based on established academic databases (Scopus, Web of Science, ScienceDirect). The analysis highlights key themes, including Islamic finance's alignment with universal ethical principles, its role in fostering financial inclusion and social impact projects, and its progressive convergence with ESG standards. Findings indicate the growing relevance of Islamic financial instruments "such as green Sukuk, Takaful, and productive Waqf" in supporting responsible and sustainable development initiatives. However, challenges remain in areas such as regulatory standardization, governance, and global visibility. The study concludes that beyond its religious origins, Islamic finance has the potential to serve as a strategic driver for ethical financial transition, provided its frameworks for transparency, education, and innovation are strengthened.

| Abstract: | Résumé Dans un contexte mondial marqué par des crises financières, sociales et environnementales, la recherche de modèles économiques alternatifs et durables devient une priorité. Cet article propose une revue systématique de la littérature sur la finance islamique, afin d'évaluer sa contribution en tant que modèle financier éthique et durable. À travers l'analyse de 62 articles publiés entre 2010 et 2024, la recherche examine les fondements, les instruments, les champs d'application et les limites de la finance islamique face aux défis contemporains. La démarche méthodologique suit le protocole PRISMA, intégrant une stratégie de sélection à partir de bases de données académiques reconnues (Scopus, Web of Science, ScienceDirect). L'analyse des publications permet de faire émerger plusieurs axes majeurs : la capacité de la finance islamique à intégrer des principes éthiques universels, sa contribution à l'inclusion financière et au financement de projets à impact social ou environnemental, ainsi que sa convergence progressive avec les normes ESG. Les résultats mettent en évidence la pertinence croissante des instruments islamiques (Sukuk verts, Takaful, waqf productif) pour financer des projets responsables et durables. Toutefois, des défis persistent en matière de standardisation, de gouvernance et de reconnaissance internationale. La recherche conclut que la finance islamique, au-delà de sa dimension religieuse, peut constituer un levier stratégique pour une transition financière plus éthique, à condition de renforcer ses mécanismes de transparence, de formation et d'innovation.

| Abstract: | This paper investigates whether counties positioned upstream in river networks—those physically first in line for stream flow under riparian water rights—experience greater resilience in agricultural land values and crop productivity during drought. Using county-level panel data from 1950 to 2022 across the Eastern United States, we combine agricultural outcomes with geospatial measures of stream proximity and groundwater access, and evaluate their interaction with standardized precipitation anomalies. Benchmark specifications show that groundwater access consistently enhances farmland value and yields, while stream access yields more nuanced patterns: downstream access is associated with higher farmland values under normal conditions, whereas upstream access is negatively associated with corn yields on average and shows limited benefits under extreme drought. However, upstream counties exhibit higher farmland values under prolonged dryness and greater corn yield gains during wet years—benefits not observed for soybean yields or in downstream areas. These results suggest that upstream proximity offers conditional advantages tied to crop water sensitivity and climate regime. As drought risk intensifies, this study provides the first systematic empirical evidence on how spatial positioning within stream networks under riparian doctrine shapes the economic geography of agricultural resilience. |

| Abstract: | There is a growing need to develop a tool to evaluate the effectiveness of conservation policies aimed at reducing nitrogen loading in agricultural production. However, existing agricultural production models often fail to accurately represent farmers’ decision-making processes regarding nitrogen fertilizer use, particularly in relation to other crop management practices such as crop rotation and tillage. This paper presents a novel modeling framework that endogenizes the yield response to nitrogen in agricultural production models. By integrating a continuous yield response function based on the Mitscherlich-Baule formulation, the framework captures the interrelated decisions of nitrogen application, crop rotation, and tillage practices. Calibrated to Minnesota agriculture, the model successfully replicates observed land allocation, tillage choices, and nitrogen use while providing enhanced responsiveness to policy incentives. The results demonstrate that this approach not only improves the representation of farmer behavior but also serves as a valuable tool for evaluating conservation policies aimed at reducing environmental nitrogen loading. |

| Abstract: | Assessing Sovereign Climate-related Opportunities and Risks (ASCOR) is an investor-led initiative launched to provide comprehensive and comparable assessments on how sovereigns are managing the low-carbon transition as well as the physical risks stemming from climate change. ASCOR aims to inform, support and facilitate investment decisionmaking, especially by sovereign bondholders, and enable a more explicit consideration of climate change at the national level. In 2023, following a public consultation, the Transition Pathway Initiative Centre (TPI Centre) at the London School of Economics (LSE), launched the ASCOR tool including the first assessments of 25 pilot countries. In 2024, a larger universe of 70 countries was assessed. This progress note announces the list of 85 countries that will be assessed in 2025, provides a description of the project’s timeline and explains recent amendments to the ASCOR methodology and dataset. |

| Abstract: | Just transition describes the transformation towards greener, more inclusive, and more resilient economies and societies. This realist review provides a rigorous summary of global evidence on interventions targeting outcomes contributing towards a just transition in developing countries, spanning energy, agriculture and food, infrastructure, and ecosystem services. We found common enablers for just transition interventions across all or most sectors, including robust funding and financing mechanisms, strong alignment with needs and priorities, political will and ownership, social dialogue and stakeholder engagement. Hard and soft enablers differed across sectors. We also found common barriers to successful just transition across all sectors, including bureaucratic and legal barriers, exclusion and unequal distribution of benefits. |

| Abstract: | This report consists of a submission by CETEx made in response to the open consultation by the Bank of England CP10/25 — Enhancing banks’ and insurers’ approaches to managing climate-related risks — Update to SS3/19. The consultation paper sets out the Prudential Regulatory Authority’s (PRA) proposals on updated supervisory expectations for banks and insurers. The proposals would help banks and insurers manage the effects of climate change on their businesses, and thereby maintain the essential services they provide to the economy. This consultation response offers several avenues to refine the proposed PRA approach, drawing on research across the LSE’s Grantham Research Institute on Climate Change and the Environment. |

| Abstract: | Federally managed dams are designated specific purposes in the legislation associated with their construction. Dams constructed and managed by the U.S. Army Corp of Engineers are typically focused on transportation and flood control, although they can have multiple other purposes including water supply for agriculture, hydroelectric power generation, and recreation. These purposes are often competing and some of them were added post construction. The competition of mutually exclusive resource allocation endeavors creates conflicts which can escalate to claims against the federal government. This research assesses the development of federally managed water resource conflicts over the past 80 years through legal proceedings. A hazard regression and count data model regression test a hypothesis that an increase in the number of objectives managed for increases litigation risk for water management agencies. This research informs an implication of multi-objective environmental management in a time of increasing responsiveness to special interests. |

| Abstract: | Recent definitions of Integrated Pest Management (1PM) put more emphasis on the ecological approach to pest management and the need to involve end-users in the technology development process (Joffe, 1998, Meerman, 1999). This approach brings to the fore major differences between IPM and other technical innovations that should force agriculturists to begin to look at IPM with the eyes of environmentalists. Agriculturists are trained to provide clear recommendations to farmers, based on research conducted at centralized experiment stations, and to expect changes in the shortest possible time, often without much concern for the environment Policies and regulatory measures support this approach. The focus of this paper is to present participatory IPM as "a set of best management practices", worked out with farmers and given for a particular context and environment. A greater emphasis is placed on protection rather than production. The strategies to be adopted are therefore expected to be inconsistent with those used to promote commercial innovations, and more in line with environmental innovations. This could be challenging. Several of the issues that would confront development institutions and agriculturists if a new perspective were to be taken are discussed. Extension would need to shift from individual to community adoption, adjust expectations of short-term results, and place much more emphasis on the environment-specific Indigenous Technical Knowledge (ITK) that resides in communities. Policy-makers would need to develop a different set of policy instruments and regulatory mechanisms, research would have to be conducted on-farm, and research, extension and farmers must work together. A participatory approach must be taken. As overall objectives shift, economists so far not directly involved must now make their input The importance of taking this approach, and its potential, are discussed from the context of the several examples of IPM initiatives in the region. |

| Abstract: | This study examines the impact of certain soil management practices, including the adoption of cover crops and no-tillage, on soil organic carbon (SOC) levels in the United States (U.S.). Using a novel county-level panel data set with information on SOC levels and remotely sensed cover crop and no-tillage acreage for 16 states from 2005 to 2019, we estimate linear panel fixed effect econometric models to investigate the impact of these conservation practices on SOC. Preliminary results suggest that counties with higher adoption of no-tillage practices have statistically higher SOC levels. However, the effect of cover crop adoption on SOC is statistically insignificant during the study period. These findings suggest that no-tillage may be an effective practice for improving SOC, while cover crops may require longer time horizons or additional complementary practices to achieve a significant impact. Results from our empirical analysis provide new evidence on the relationship between conservation practices and SOC, offering valuable insights for policymakers and farmers considering the adoption of these practices to improve soil health and sustainability. |

| Abstract: | The most extensive markets for pollination services in the world are those for honey bee pollination in the United States. They play important roles in coordinating the behavior of agricultural producers and migratory beekeepers, who both produce honey and provide pollination for crops. Recent trends in bee disease–including the still poorly understood Colony Collapse Disorder, or CCD–can usefully be viewed in the context of how markets respond to environmental change. We analyze economic indicators of input and output markets related to managed honey bee operations, looking for effects from CCD. We find strong evidence of adaptation in these markets and remarkably little to suggest dramatic and widespread economic effects from CCD. |

| Abstract: | This paper investigates the nexus between subjective well-being and sustainability, proxied by the Sustainable Development Goals (SDG) Index, using cross-country data from 126 nations in 2022. While prior research has highlighted a positive association between happiness and sustainable development, existing approaches largely rely on linear regressions or correlation-based measures that mask distributional heterogeneity, multicollinearity, and potential nonlinear dependence. To address these limitations, we employ a two methodological framework combining Graphical Lasso, and Quantile-on-Quantile Regression (QQR). The Graphical Lasso identifies a direct conditional link between happiness and sustainability after controlling for governance, income, and life expectancy, with a partial correlation of about 0.21. On the other hand, QQR reveals heterogeneous effects across the joint distribution: sustainability gains are positively associated with happiness for low-happiness but high-sustainability countries, negatively associated in high-happiness but low-sustainability contexts, and essentially neutral elsewhere. These findings suggest that the happiness-sustainability link is modest, asymmetric, and context-dependent, underscoring the importance of moving beyond mean-based regressions. From a policy perspective, our results highlight that institutional quality, income, and demographic factors remain the dominant drivers of both happiness and sustainability, while the interplay between the two dimensions is most pronounced in distributional extremes. |

| Abstract: | Stray livestock and the associated problems are not new or limited to underdeveloped countries. The approaches developed vary from place to place and from time to time, dependent on the particular circumstances. In 2001, Grenada experienced one of the severest dry seasons. This resulted in an intensification of problems associated with stray animals. In Carriacou, in particular, the economic impact of stray livestock is significant, limiting crop production through high costs of fencing and crop damage, degrading the environment, reducing stock number and stock breeding quality, polluting public places and putting at risks vehicular traffic Current legislation dating back to 1850's has proven to be inadequate as it has not addressed the root causes of stray animals. Some of the causes relate to (i) issues of land tenure including landlessness of livestock farmers and competition between crop and livestock farmers for space (ii) livestock management including overgrazing and overstocking (iii) socio-economic and legal issues including poverty and unemployment. To adequately respond to the negative and costly impact of stray livestock, proposed solutions need to be informed by root causes of the stray livestock problems and should be focused on sustainability. Such solutions would have implications for the Government and Ministry of Agriculture. The Ministry of Agriculture needs to review its livestock programs, making them more appropriate to the capacity of the livestock farmer. Public awareness and education on the issues surrounding livestock production and the stray livestock problem, would be critical to a process expected to reduce the number of stray animals and the improvement of livestock production in particular. Some concrete recommendations which are policy and management oriented are offered, some or all of which may be taken up in addressing the stray animals problem. |

| Abstract: | The expansion of intermittent electricity increases supply variability and requires greater flexibility from consumers. This results in welfare losses for these agents, which can nevertheless be mitigated by energy storage. Our model analyzes these welfare consequences in the context of short-term variability in renewable energy given fixed dispatchable and storage capacities. We explore an optimal control problem that determines a welfare-maximizing electricity consumption path by adjusting dispatchable and stored energy throughout the short-term production cycle of renewables. This optimization problem identifies three regimes (no storage and active storage, with or without capacity constraints) and provides the associated consumer welfare over this cycle. Under all three regimes, a certain degree of consumer flexibility is part of the optimal solution and entails welfare losses. Active storage reduces these losses but cannot eliminate them completely due to the energy conversion losses induced by this activity. However, when storage capacity is constrained, a proactive adjustment of this capacity can offset the losses. |

| Abstract: | Management of public lands often involves competing uses and difficult tradeoffs. Here we examine the implications of a direct federal land use conflict in Cape Hatteras National Seashore: off-road vehicle (ORV) access and endangered species protection. Results from a repeated discrete choice model of recreational angler behavior suggest that the economic costs of access restrictions are relatively modest, ranging from $403, 000 to $2.07 million annually. Our results provide general support for the National Park Service’s recently implemented ORV management plan, as the upper bound of recreation losses is less than a conservative estimate of the benefits of protecting coastal biodiversity. |

| Abstract: | We investigate the relationship between biodiversity and municipal finance. At the county level, municipalities experience higher borrowing costs due to increased biodiversity exposure, significantly affecting both intensive and extensive margins. A one-standard-deviation increase in biodiversity exposure raises municipal bond yields by 42.4 (63.3) basis points (bps) dependent on the ecological and economic controls, while the extensive margin of bond issuance decreases by 0.61%. Our analysis highlights pricing heterogeneity based on regional species protection awareness finding that species awareness facilitates to mitigate the financial cost. This economic mechanism is driven by the effect of biodiversity conservation over real estate market, reflected in enriched biodiversity and lower credit ratings. Utilizing the federal Endangered Species Act (ESA) as an exogenous shock, we causally identify that the observed pricing pattern results from stringent species protection policies. |

| Abstract: | This paper assesses food security in Uzbekistan, focusing on agricultural diversification, policy reforms, and sustainability challenges. Since gaining independence, Uzbekistan has reduced its reliance on cotton and wheat, expanding production of fruits, vegetables, and livestock to enhance self-sufficiency and improve rural livelihoods. Using secondary data, international reports, and policy analyses, the study identifies progress in reducing hunger and increasing the output of high-value crops. However, constraints such as limited processing infrastructure, water scarcity, dependence on imports, and rural micronutrient deficiencies persist. Recommendations emphasize diversification, technological innovation, and aligning strategies with the Sustainable Development Goals to ensure resilient and sustainable food systems and improved national food security outcomes. |

| Abstract: | Amid ongoing policy discussions around water scarcity in the Colorado River Basin, we examined factors influencing farmers’ stated participation in agricultural water conservation programs (AWCPs) in Colorado’s Upper Basin. Using data from a discrete choice experiment, we assessed preferences for hypothetical program attributes and payment levels. Respondents preferred AWCPs with shared conservation responsibility, water shepherding, and higher compensation. Participation declined for more intensive conservation practices and larger land commitments. Larger farms required lower payments to participate, while older and higher-income farmers required more. The findings identify program attributes, such as flexibility and transparent water use outcomes, that can help policy makers drive voluntary participation in AWCPs. |

| Abstract: | The transport sector remains one of the main contributors to global GHG emissions, making the shift toward more sustainable mobility a key component of climate-mitigation strategies. While previous research has emphasized the role of infrastructure, technology, and behavioral change, less is known about how public attention toward sustainable transport evolves and diffuses across countries. This paper uses Google Trends data as a high-frequency indicator of public interest in sustainable mobility for 38 OECD countries from 2004 to 2025. To ensure comparability across time and space, we propose the construction of log-ratios between sustainable mobility and conventional car-related searches so that the measure is robust to changes in Google’s user base. We apply the Phillips and Sul convergence framework to test whether attention levels follow common long-run trajectories. Results show strong convergence in electric-vehicle attention, while hybrid- and public-transport interest remain fragmented. Validation analyses confirm that Google Trends indicators correlate with subsequent electric-vehicle adoption, underscoring their value as dynamic proxies for cultural and behavioral dimensions of sustainable mobility. |

| Abstract: | For years, the U.S. Department of Agriculture, and increasingly private incentive programs, have provided financial assistance to farmers to plant new forestland in place of commodity crops. Afforestation of cropland can provide multiple ecosystem services. However, as with any voluntary incentives, an increase in ecosystem services depends on the degree to which realized afforestation is additional and persistent. Incentives are additional if farmers would not have switched to timber without government assistance; and defined as persistent if managers of new timberland do not simply return their land to crops after their afforestation contracts end. In this study, we assess the long-run impacts of incentives for afforestation of cropland in USDA’s Conservation Reserve Program. We estimate impacts using a regression discontinuity design, relying on the Conservation Reserve Program’s General Signup auction mechanism. We use remote-sensing data to detect the extent of trees within tracts of land that rejected and accepted offers in the program. We find that more than 50 percent of land enrolled is additional; and that impacts are persistent as well, with most long-run impacts coming from parcels that have exited the program. |

| Abstract: | This study examines barriers to conservation drainage adoption despite cost-share incentives in the U.S. Midwest. Using survey data from 530 farm operators across the Corn Belt, we employ probit model, boosted regression trees, and latent class analysis to analyze factors influencing farmer non-acceptance of 50% cost-share programs for controlled drainage, saturated buffers, and wetland restoration. Results reveal substantial non-acceptance rates of 54.5-68.1% across practices. Probit models show that neighbor adoption reduces non-acceptance probability by 12.3 percentage points for controlled drainage, while higher liability-to-asset ratios consistently increase responsiveness to financial incentives across all practices. Machine learning analysis reveals that climate variables and geographic location are heavily influential in adoption decisions. Latent class analysis identifies four distinct farmer types, suggesting that uniform conservation programs are inadequate for addressing farmer heterogeneity. Understanding farmer heterogeneity and designing targeted interventions will be key to achieving widespread adoption of sustainable drainage practices. |

| Abstract: | Economies around the world are simultaneously undergoing two profound changes: the 'green' (sustainability-focused) transition and the 'automation’ (digital-focused) transition. This dual or ‘twin’ transition has significant implications for the tourism industry, which is a crucial source of employment for many countries. This paper explores the potential for transitions to green and digital jobs in the tourism industry. We analyse household survey data for the seven largest economies of Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, and Uruguay) for the period 2011-2024. Our main results show that the tourism sector in Latin America has high potential to reallocate workers from brown to green jobs, thereby reducing the adjustment costs of decarbonization. This capacity is particularly pronounced in Mexico and Ecuador, and is especially strong among younger cohorts, men, and workers with lower levels of formal education. |

| Abstract: | How do climate shocks shape resource allocation across firms? Rising temperatures might worsen allocative efficiency if large, productive firms face constraints in adapting. This paper assesses this question in India, an economy characterized by informality, misallocation, and extreme heat. The paper uses census data on 42 million non-farm establishments from 1990 to 2013 linked to granular climate histories to estimate the impact of heat on the firm size distribution. A 1 degree Celsius temperature shock reduces firm size by 11.6 percent, with losses concentrated among large, formal firms. Displaced workers reallocate to smaller, informal firms, generating allocative efficiency losses of up to 4.3 percent. In long difference estimates spanning several decades, the relationship reverses: large firms adapt and absorb labor, while small firms contract. This adaptation offsets nearly 60 percent of the short-run labor demand shock. These results highlight a general mechanism of climate adjustment: in the short run, shocks exacerbate misallocation by pushing labor into low-productivity firms, but in the long run, adaptation by larger firms restores efficiency. |

| Abstract: | ASCOR is an investor-led initiative launched to provide comprehensive and comparable assessments on how sovereigns are managing the low-carbon transition as well as the physical risks stemming from climate change. This report outlines use cases for the ASCOR tool, organised by user type: investors and sovereign bond issuers. We explain how these users might harness the ASCOR tool for their respective needs. The potential use cases and practical case studies are gleaned from the TPI Centre’s research and outreach through bilateral meetings, webinars and roundtables with various stakeholders. The report is designed to expand awareness of the practical applications of the ASCOR tool as well as stimulate greater use. |

| Abstract: | Little is known about how various greenhouse gas mitigation policies will impact the market structure of U.S. agriculture. Existing and proposed policies can increase the cost of carbon-intensive farm inputs, directly or indirectly, similar to a carbon price or tax. Using farm-level data, we assess the ex-ante distributional impacts of a hypothetical carbon price on fuel-intensive inputs. Structural cost functions are first estimated for corn operations by farm typology in the Corn Belt, and the results are used to predict the effects of a carbon price on short-run total costs. A novel statistical test is then employed to determine if a carbon price would be regressive across farm typologies. Our findings suggest that a short-run exogenous carbon price would be regressive for smaller farms, while larger farms are able to better adapt to higher input costs. This regressivity becomes especially noticeable at threshold level above $10 per ton of carbon. |

| Abstract: | This paper examines two drastic changes in the performance of local water associations in providing local public goods – appropriate levels of water table – in the reclamation system in the Powiat Pyrzyce in the Voivodship Zachodniopomorski in northwest Poland. Employing an institutional economics approach shows the results of processes of revalorisation of the interrelated property objects land and reclamation infrastructure that have been triggered and shaped not only by the drastic political, economic and administrative changes after the breakdown of the socialist regime in Poland in 1990, but also by the prospect of joining the European Union and the proactive leadership of the director of the Powiat Department of Environmental Protection, Forestry and Agriculture. More precisely, both processes – the discontinuation (from 1990 onwards) and revival (from 2002 onwards) of the local water associations – were mainly determined by changing market conditions together with variances in the ability of state authorities to effectively control and facilitate these associations. Further, the delay in overcoming the period of collective inaction was fostered by the time-delayed and cumulative effects of neglecting the cleaning and the maintenance of secondary ditches. |

| Abstract: | This paper presents a novel model comparison to examine the challenges for monetary policy posed by changes in carbon-intensive energy prices. The environmental monetary models employed have a detailed multi-sector structure. The comparison assesses the effects of both a temporary and a permanent energy price increase, with a particular focus on the euro area and the United States. The temporary and permanent price shocks are both inflationary. However, the inflationary impact of the permanent shock depends on the underlying model assumptions and monetary policy response. In addition, the analysis establishes that these models share significant commonalities in their quantitative and qualitative results, while also revealing cross-country differences. |

| Abstract: | Reaching global net-zero by 2050 requires rapidly scaling low-carbon hydrogen, but deployment is hindered by market uncertainty, high capital costs, and weak supply-demand coordination. This paper examines whether liberalizing international hydrogen and ammonia trade can accelerate deployment and how such policies interact with technological innovation. We develop a hybrid framework combining a global TIMES-based energy-system model (KiNESYS-IFPEN) with a stochastic logistic diffusion model calibrated to historical renewable energy growth under imperfect expectations. We find that trade liberalization alone has limited global impact, and mainly reallocates production geographically: the Middle East, North America, Latin America, and China expand as exporters, while Asia Pacific, Europe and Africa become structural importers. Innovation-driven electrolyzer cost reductions raise significantly global deployment success shifting production toward electrolysis. When policies are combined, innovation dominates, while trade openness reinforces regional specialization. These results underscore the central role of technological progress, credible expectations, and the trade-off between cost-efficient specialization and hydrogen supply security. |

| Abstract: | This paper evaluates the drinking water quality impacts of stricter state regulations for PFAS contaminants. A key challenge of this analysis is the wide prevalence of interval censoring in PFAS testing. I first show that without further assumptions, treatment effects are not generally identified and applying standard approaches that ignore this issue lead to qualitatively different results. I overcome this problem using a parametric approximation to recover the latent cumulative distribution function through censored maximum likelihood. I implement the changes-in-changes approach using the recovered distribution of concentration to estimate the impact of tightening regulatory standards on water quality. On the intensive margin, I find that notification level changes had no impact on water quality across the distribution. On the extensive margin, I find qualitative evidence of investment in the form of new or retrofitted treatment plants to address PFAS after notification and response levels became more stringent. I find these new treatment plants tend to be located in urban and above average income counties. The methods implemented allow for policy evaluation under interval censoring in a variety of contexts. |

| Abstract: | Drought is a major factor contributing to agricultural production losses in Alabama, bringing tremendous challenges to agricultural productivity and food security, but its impact on farmland value is still lacked. This study investigates the influence of droughts on farmland value in the State of Alabama from 2007 to 2021. We combine a unique parcel-level farmland data set with drought information provided by United States Drought Monitor (USDM). Based on hedonic price method, we employ spatiotemporal fixed effect models, a newly developed moment-based instrumental variable model and kinky least square method as well as several robustness checks, finding longer periods of drought exposure can lead to farmland value reduction, and its long-term impacts are stronger than short-term, reflecting such influences on market are gradual and slowly. We also reveal that the land value response to drought stress is heterogenous, across different land use types, rural-urban divisions, ownership types as well as agricultural policies coverage. Our findings highlight the critical role for climate-resilient adaptation strategies in land use policies. |

| Abstract: | International trade networks are increasingly vulnerable to disruptions from natural disasters, yet the resilience of global trade flows remains insufficiently understood. This study examines how different types of natural disasters—including earthquakes, droughts, extreme temperatures, floods, and storms—affect bilateral trade, and investigates whether structural factors such as export diversification and sectoral positioning shape trade resilience. Our analysis proceeds in two stages. In the first stage, we employ a gravity model estimated using Poisson Pseudo Maximum Likelihood (PPML) on bilateral trade data from Comtrade and disaster data from EM-DAT to quantify the impact of disasters on export volumes. We find that upstream industries experience the most severe trade contractions—particularly due to extreme temperatures and storms—while downstream industries are relatively less affected. In the second stage, we adopt a moment-based three-step method to assess trade resilience by estimating the conditional probability of trade stability following a shock. Our results indicate that export diversification enhances resilience, but its effectiveness varies by economic context: high-income countries benefit more from complexity-driven trade adjustments, whereas low-income economies are more adversely affected by disruptions. Additionally, we find that disasters in trading partner countries generate strong spillover effects in vulnerable economies. |

| Abstract: | Résumé : Cet article analyse l'impact de l'inclusion dans l'indice MASI ESG de la Bourse de Casablanca sur la performance boursière des entreprises cotées. Dans un contexte où les critères environnementaux, sociaux et de gouvernance (ESG) prennent une importance croissante dans les décisions d'investissement, la recherche vise à déterminer si l'appartenance à un indice ESG améliore effectivement la performance ajustée au risque sur le marché marocain. L'étude repose sur une base de 782 observations couvrant la période de novembre 2023 à juin 2025. Trois indicateurs de performance ont été retenus — le rendement mensuel, la volatilité et le ratio de Sharpe — afin d'évaluer la performance ajustée au risque. Les données ont été traitées à l'aide du logiciel SPSS, en mobilisant des statistiques descriptives et une analyse de régression linéaire destinée à tester l'effet de l'inclusion ESG sur le ratio de Sharpe. Les résultats empiriques révèlent une relation positive et statistiquement significative entre l'inclusion dans l'indice MASI ESG et la performance ajustée au risque. Les entreprises affichant de meilleures pratiques ESG présentent globalement une volatilité plus faible et une rentabilité ajustée supérieure, suggérant que le MASI ESG constitue un signal de confiance pour les investisseurs et un levier de développement de la finance durable au Maroc. Abstract: This paper examines the impact of inclusion in the MASI ESG index of the Casablanca Stock Exchange on the stock market performance of listed companies. In a context where environmental, social, and governance (ESG) criteria are becoming increasingly important in investment decisions, the study seeks to determine whether ESG index membership effectively enhances risk-adjusted performance in the Moroccan market. The analysis is based on a dataset of 782 observations covering the period from November 2023 to June 2025. Three performance indicators were considered—monthly return, volatility, and the Sharpe ratio—to assess risk-adjusted performance. Data were processed using SPSS, combining descriptive statistics with a linear regression analysis testing the effect of ESG inclusion on the Sharpe ratio. Empirical results reveal a positive and statistically significant relationship between inclusion in the MASI ESG index and risk-adjusted performance. Firms with higher ESG standards exhibit lower volatility and superior adjusted returns, suggesting that the MASI ESG index serves as a credible signal for investors and a lever for promoting sustainable finance in Morocco. |

| Abstract: | This study uses data from a discrete choice experiment in the northeastern U.S. to examine resident preferences for siting wind and solar energy projects. It explores the impacts of landscape, agricultural production, cooperation, and financial compensation to stakeholders. Findings suggest that households are more favorable to renewable energy development if subsidies are provided on their electricity bills. Key factors influencing decisions include visual impact, proximity, and community engagement. Payments to landowners and communities also play a significant role in shaping local support and acceptance. Our study further reveals considerable heterogeneity in preferences. Respondents demonstrated overall support for wind or solar farm development in their local community, though preferences differed among various demographic and attitudinal groups, with the average respondent willing to be compensated $88 less in their base electric bill. |

| Abstract: | ABSTRACT This research investigates the determinants of sustainability reporting practices within multinational companies (MNCs) and their subsidiaries, focusing on the mediating role of MNC parents and the moderating impact of cultural distance and local isomorphism. We conducted a content analysis of the stand‐alone sustainability reports of 187 MNCs and 332 subsidiaries over a decade (2011–2020), comparing 1594 subsidiary reports with 983 parent reports. A path analysis approach assessed the mediating role of MNC parents, while random effects panel models assessed the moderating effects of local isomorphism and cultural distance. The results indicate that MNC parents positively and significantly influence the adoption of sustainability reporting practices by their subsidiaries. However, the successful implementation of these practices is moderated by local institutional context and cultural distance. Subsidiary transparency was positively influenced by industry characteristics and effective local governance, while financial constraints and the degree of alignment with international standards played a complex role in reporting practices. Our research indicates that MNCs need to adjust their global approaches to fit into local environments and improve the transparency of subsidiaries by utilizing industry‐specific tactics and robust local management. Policymakers need to prioritize enhancing local governance structures to improve sustainability reporting. This research contributes to the field of institutional theory by demonstrating how local isomorphism affects the dissemination of reporting practices within MNCs. Furthermore, it is one of the few recent studies to examine sustainability reports in‐depth, analyzing their content and assessing the extent to which cultural distance affects the adoption of transparency practices global. |

| Abstract: | Growing environmental concerns necessitate shifts towards sustainable purchases, such as reusable packaging like glass milk bottles. However, A key barrier is the behavioral complexity requiring consumers to both purchase the product and return the packaging. We investigated whether financial incentives could foster habit formation using a 21-week field experiment with 6, 735 co-op members of a grocery store randomized to Control, Purchase Incentive (PI), or Return Incentive (RI) groups for local, glass-bottled milk. Analyzing the scanner data and survey responses, we found that while both incentives significantly boosted sales during the 7-week intervention, these effects were temporary and did not translate into lasting purchase habits. Similarly, bottle returns increased modestly during the intervention but did not persist. Furthermore, contrary to expectations, the RI did not significantly outperform the PI in promoting bottle returns. Low incentive redemption, consumer default choices, and the inconvenience of returns emerged as potential obstacles. Our results suggest that temporary financial incentives alone, such as coupons, are insufficient to establish habits for multi-step sustainable behaviors. It is important to address structural barriers like convenience and underlying consumer preferences. |

| Abstract: | This paper estimates the potential flood risks for the banking system in France through the non-financial corporation channel. We show the importance of going granular in assessing physical risk. First, the aggregate economic losses at the establishment level appear much higher than at the headquarter level. Second, the losses associated with transferable assets (machines and equipment) are greater than those related to real estate assets. The deterioration of these two types of assets affects the banking system through different channels. Property damages reduce the owner NFC’s assets and increase the Loss Given Default (LGD) associated to the premise, while transferable damages can affect the cash position and leverage of the occupier NFC and thus the probability of default. Bank losses associated with transferable assets (the content) are more severe than those affecting properties (the container). Current insurance schemes in France reduce flood vulnerability not only directly for firms but also limit the amplification of vulnerability through the banking system. |

| Abstract: | Catastrophe risk has long been recognized to pose a serious threat to the insurance sector. Although natural disasters such as flooding, hurricane or severe drought are rare events, they generally lead to devastating damages that traditional insurance schemes may not be able to efficiently cover. Catastrophe risk pooling is an effective way to diversify the losses from such risks. In this paper, we improve the catastrophe risk pool by Pareto-optimally allocating the diversification benefits among participants. Finding the practical Pareto-optimal pool entails solving a high-dimensional optimization problem, for which analytical solutions are typically unavailable and numerical methods can be computationally intensive and potentially unreliable. We propose evaluating the diversification benefits at the limit case and using it to approximate the optimal pool by deriving an asymptotic optimal pool. Simulation studies are undertaken to explore the implications of the results and an empirical analysis from the U.S. National Flood Insurance Program is also carried out to illustrate how this framework can be applied in practice. |

| Abstract: | A secondary adoption study of Soil Conservation (SC) practices, principally rock walls, alley cropping, contour terraces, crop bands, and contour canals was conducted in Haiti during the months of August and September 1998. A total of 101 farm heads of households who had not been included in a recent SC project were interviewed to determine their source of information on the adoption of soil conservation practices. The sample of heads of household included 91 males and 10 females within the ages of 17 to 75 years. It was found that land tenure system affected the adoption of SC practices and soil fertility positively affected the installation of SC practices (p>.05). Most farmers indicated that their information for the adoption of SC practices come from the following: 17.1% from their own experience, 12.0% from other, and 5.7% from friends. Only 1.3% revealed that they obtained the information from the on-going project, while 9.5% said they received it from another contemporary project. |

| Abstract: | This study investigates the causal relationship between climate shocks and women’s experiences of physical intimate partner violence (P-IPV) in rural India. Using geo-coded weather data linked to domestic violence reports from the two recent rounds of the Indian National Family Health Survey (NFHS 2015–16 and 2019–21), I find that droughts, wet shocks, and extreme heat during the most recent kharif growing season significantly increase the likelihood of women experiencing P-IPV. Specifically, exposure to a drought during the growing season increases the prevalence of less-severe P-IPV by 11.6%, while wet shocks increase severe P-IPV by 30.6%. Heat stress, measured as cumulative degree days above 30°C, is also associated with higher rates of both less-severe and severe IPV. Further analysis suggests that increased economic insecurity, husband’s alcohol use and marital controlling behaviors, and a decline in women’s empowerment are central pathways underlying these effects. Additional heterogeneity analyses reveal that household characteristics — such as land ownership and bank account access play a protective role by offering formal or informal insurance that helps buffer the harmful effects of drought on P-IPV. |

| Abstract: | We estimate the impact of infrastructure investment on conflict using 163 hydroelectric dams in Brazil (2002–2022). Leveraging the staggered rollout of construction in a difference-in-differences framework, we find that dams trigger sharp, temporary surges in land invasions, water disputes, and homicides. These effects peak during construction and dissipate upon operation, suggesting they stem from the displacement process rather than the public good itself. Crucially, conflict is mediated by local institutions: violence occurs only where property rights are weak and displacement affects vulnerable smallholders. Our results demonstrate that without effective compensation, state-led modernization generates destabilizing redistributive shocks. |

| Abstract: | The European Union (EU) has made progress in managing construction and demolition waste (CDW), but more needs to be done to promote preparing for reuse and high-quality recycling. The scope of the current study is the universe of policy measures intended to reduce waste, increase recycling, and achieve cost savings in CDW management in the EU. This study serves to define the state-of-play in the EU and winnow the universe of policies to those that are most promising given current technological and market conditions. Based on analysis of the policies with the highest potential positive impacts, the Joint Research Centre (JRC) recommends considering eight targeted actions at the EU level and ten additional targeted actions at the national and local levels to improve CDW reduction, reuse, and recycling. These policy measures range from legally binding rules to soft regulation and include measures such as extending producer responsibility, promoting selective demolition, and harmonising landfill charges. The measures require further in-depth impact assessment if promoted. The current study offers reliable evidence based on quantitative/qualitative analyses that provide new empirical data and results for use in future impact assessments. |

| Abstract: | Excess stormwater runoff is a major environmental challenge in the U.S. Green infrastructure, including rain gardens, permeable pavement, and backyard infiltration, offers an effective solution for mitigating the negative impacts of excess stormwater runoff in urban landscapes. In an effort to encourage homeowners to adopt these practices, many cities have implemented voluntary, cost-sharing stormwater grant programs. Despite financial incentives, households’ participation in these programs has been low. Recent research suggests that transaction costs may be an important barrier to the adoption of urban stormwater BMPs. To investigate this, we conducted a choice experiment to estimate the effect of specific transaction costs associated with BMP program features on residents’ participation. Our findings indicate that residents perceive high transaction costs related to factors such as longer time spent on application paperwork and coordinating contractors, installation delays, and the absence of on-call technical support, which can affect their enrolment decision. Our WTA estimates show that perceived transaction costs are sufficient to offset the financial incentive of the cost-share stormwater program. |

| Abstract: | The adoption of integrated pest management practices has been widely promoted in low- and middle-income countries to enhance farmers’ economic outcomes. The main challenge is the lack of quantitative synthesis of scholarly works to ascertain whether, for farmers in these countries, those who adopt a single component or a full bundle of integrated pest management practices achieve higher yields, farm income, food security and reduced pesticide use compared to non-adopters. The review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) methodology. A total of 24 studies were used for the review based on strict inclusion and exclusion criteria. Meta-analysis was employed to combine the individual and overall effect sizes across these studies. The results indicate that there is evidence that adopting integrated pest management practices has the potential to lead to a large improvement in crop yield for farmers. The findings also reveal that such adoption causes a small effect in food security level, and a moderate to large effect in farm income for farmers. The evidence further suggests that adopting these practices does not directly lead to behavioural change among farmers in reducing synthetic pesticide use. Overall, the findings demonstrate that adopting integrated pest management practices is a promising strategy for improving farmers’ economic outcomes in low- and middle-income countries. Policymakers and development partners should not only focus on IPM programmes for economic improvements for farmers, but also address behavioural barriers to ensure effective and consistent adoption for the desired environmental benefits |

| Abstract: | Environment-related investments represent challenges for private sector firms due to uncertainty about their future impact on corporate value and capital formation. Previous empirical research has overlooked such incentive structures. Following the approach of Brynjolfsson, Rock and Syverson (2021), we estimated a firm value function with multiple assets including environment-related R&D as explanatory variables, based on the concept that associated costs of capital accumulation can contribute to future productivity improvements. Our estimation for manufacturing firms finds that environmental R&D contributes to firm value positively and significantly. These effects are particularly evident in large firms and those engaging in technology trade. This suggests that such investments facilitate technological accumulation to meet the demands of international consumers and regulatory frameworks. However, recent shifts in global policy such as the U.S. withdrawal from the Paris Agreement may weaken incentives for Japanese firms with close ties to U.S. markets. If Japan wants to continue to pursue policy that is aligned with the Paris Agreement, stronger government support for private sector environmental initiatives will be necessary. |

| Abstract: | Wind turbines play an important role in the green transition towards a pollutionfree generation of electricity. Yet, the deployment of new wind turbines faces increasing local and political opposition. The public discourse routinely goes beyond wind turbines’ established negative impact on house prices. However, evidence on how residents react to new turbines and whether human health and labor market outcomes are affected remains limited. We study how industrial-scale onshore wind turbines affect nearby communities in Denmark, combining geo-coded information on all wind turbines installed after 1995 with 25 years of administrative full-population data. Exploiting the staggered timing of wind turbine establishments in an event-study framework allowing for heterogeneous treatment effects, we estimate the impact on neighborhood composition at the address level, and on mental health and labor market outcomes at the individual level. We find small negative effects on the occupancy of houses nearby large turbines, indicating a decrease in attractiveness. However, we detect no meaningful impacts on mental health, productivity, or the socio-economic composition of neighborhoods. Overall, our evidence does not indicate large adverse health effects from proximity of wind turbines, but it is consistent with local disamenities. |

| Abstract: | Standard evaluations of public policies involve discounting the flow of expected net benefits at a unique discount rate. Consequently, they systematically ignore the insurance benefits of policies that hedge the aggregate risk, and the social cost of projects that raise the aggregate risk. Normative asset pricing theory recommends adjusting the discount rate to the project’s risk, but few countries have attempted to implement this complex solution. We explore the equivalent "stochastic discount factor" approach based on the expected value of its state-contingent NPV, using the relevant state-contingent Ramsey discount rate. Under our "stress discounting" approach, projects are evaluated under two polar risk-free economic scenarios, one business-as-usual scenario, and one low-probability catastrophic scenario. Inspired by the recent asset pricing literature on macro catastrophes, we show that this approach adequately values assets’ risk premia under a minimal, intuitive, and operationally simple departure from the standard risk-free approach with a unique discount rate. We carry out benchmarks to check the accuracy of this approach, then apply it to value a nuclear waste disposal. |

| Abstract: | In 2004, Italy introduced a national program to address heat-related health risks, combining public awareness campaigns, heat-wave warning systems, and hospital protocols. Leveraging administrative mortality data and high-frequency temperature variation, we show that the program reduced heat-related mortality by more than 57% on days at or above 30°C. To identify the mechanisms, we exploit the staggered introduction of heat-wave warning systems across provinces and show that treated areas experienced substantially larger reductions in heat-related mortality. We further document that information disclosure plays a key role in driving these reductions. Overall, our findings underscore the importance of public adaptation policies that rely on information provision to cost-effectively mitigate the health impacts of extreme temperatures. |

| Abstract: | El aumento sostenido de la demanda mundial de alimentos, impulsado por el crecimiento poblacional y el incremento de los ingresos per cápita, plantea la necesidad de producir más alimentos de manera sostenible. En este contexto, las cadenas de comercialización se configuran como un sistema complejo que requiere la articulación de diferentes actores para alcanzar la sustentabilidad. En Argentina, la producción de alimentos constituye un pilar del desarrollo económico y un componente clave de su inserción internacional como país exportador. La diversidad edafoclimática permite una amplia variedad de producciones intensivas y extensivas, asegurando el abastecimiento de alimentos durante todo el año. Sin embargo, el país enfrenta una paradoja estructural: pese a su alta capacidad productiva, persisten la pobreza y la inseguridad alimentaria. Frente a esta situación, diversas organizaciones civiles, como los Bancos de Alimentos, cumplen un rol fundamental en la reducción de desperdicio de alimentos y la redistribución solidaria de excedentes aptos para el consumo humano. En el sudeste bonaerense, el proyecto NODO -impulsado por 3 Bancos de Alimentos- constituye una experiencia significativa de articulación territorial orientada a mejorar el acceso equitativo a los alimentos. Este trabajo tiene por objetivo evaluar la actividad del proyecto NODO durante el año 2024 desde la perspectiva de la Contabilidad Social y Ambiental y su contribución a los Objetivos de Desarrollo Sostenible (ODS). Para ello, se trabaja con el enfoque de análisis de caso, conjugando datos de fuentes de información primaria y secundaria. Los resultados obtenidos evidencian una importante contribución de NODO a los ODS 2, 4, 12, 13 y 17. También, se detectó que empresas aliadas a NODO presentan Reportes de Sustentabilidad aplicando metodología de normas internacionales. |

| Abstract: | We conduct a choice-experiment with individuals that recently rented a vacation property along the North Carolina coastline to assess the impacts of a utility-scale wind farm on their rental decisions. Visualizations were presented to survey respondents that varied both the number of turbines and their proximity to shore. Results indicate that there is not a scenario for which respondents would be willing to pay more to rent a home with turbines in view, as compared to the baseline view with no turbines in sight. Further, there is a substantial portion of the survey population that would change their vacation destination if wind farms were placed within visual range of the beach. The rental discounts required to attract the segment of the survey population most amenable to viewing wind farms still indicate that rental value losses of up to ten percent are possible if a utility-scale wind farm is placed within 8 miles of shore. |

| Abstract: | In a context of global awareness of the environmental and societal impacts of human activities, regulations are multiplying to impose more responsible behavior. The european corporate sustainability and due diligence directive (CS3D) embodies this evolution by imposing specific obligations on companies. However, the issue of responsibility extends far beyond the private sector, also affecting the non-commercial sector, including civil organizations, administrations and public entities. The conference organized jointly by AFED and IRB for the second consecutive year on December 11, 2024, aimed to analyze these new obligations from an economic and legal perspective and to address the challenges raised by their implementation. These proceedings are a faithful transcription of the presentations given on this occasion at the University of Paris-Panthéon-Assas. |
| Abstract: | Dans un contexte de prise de conscience globale des impacts environnementaux et sociétaux des activités humaines, les régulations se multiplient pour imposer des comportements plus responsables. La directive européenne sur le devoir de vigilance (CS3D) incarne cette évolution en imposant aux entreprises des obligations précises. Toutefois, la question de la responsabilité s'étend bien au-delà du secteur marchand, touchant également le secteur non marchand incluant les organisations civiles, les administrations et les entités publiques. La conférence organisée conjointement par l'AFED et l'IRB pour la deuxième année consécutive le 11 décembre 2024 se proposait d'analyser ces nouvelles obligations sous un angle à la fois économique et juridique et d'aborder les défis que leur mise en œuvre soulève. Ces actes sont la fidèle retranscription des interventions qui se sont tenues à cette occasion à l'Université Paris-Panthéon-Assas. Katia Martin-Chenut (directrice de recherche au CNRS, ISJPS, Université Paris 1 Panthéon Sorbonne) est intervenue en premier lieu pour poser les principaux jalons de cette nouvelle normativité. Puis Pierre Chevalier (directeur des affaires juridiques, conformité et déontologie au sein de la Caisse des dépôts et consignations) a apporté un éclairage pratique sur la manière dont les acteurs de terrain s'approprient ces évolutions normatives, les défis qu'ils rencontrent et les solutions qu'ils envisagent. Alice Navarro (magistrate et directrice adjointe de l'Agence française anticorruption) a abordé la question des contrôles et de la supervision administrative pour une meilleure mise en œuvre du devoir de vigilance. Enfin, Chloé Le Coq (professeure en sciences économiques à l'Université Paris-Panthéon-Assas) a apporté une perspective interdisciplinaire en mettant en lumière les enjeux économiques et environnementaux qui sous-tendent ces thématiques. |

| Abstract: | European energy markets experienced unprecedented disruptions following Russia’s invasion of Ukraine on 24 February 2022, exposing long-standing structural vulnerabilities in fossil fuel–dependent systems and threatening progress toward Sustainable Development Goal 7 (SDG 7). This study provides a causal analysis of the conflict’s immediate impact on European energy markets using a Regression Discontinuity Design (RDD) that leverages the sharp temporal cutoff created by the invasion. Drawing on monthly data for 25 European countries from 2019–2024, we examine four core outcomes: natural gas import volumes, crude oil import volumes, Title Transfer Facility (TTF) natural gas prices, and wholesale electricity prices. Our findings reveal significant supply-side adjustments following the conflict, with natural gas and crude oil imports exhibiting heterogeneous responses depending on pre-war Russian dependency levels. Price dynamics show pronounced but short-lived spikes in TTF gas prices, while electricity market responses are more ambiguous due to bandwidth sensitivity. The results provide empirical evidence of how European energy systems absorbed an exogenous geopolitical shock, highlighting the interplay between supply diversification, market integration, and vulnerability to price volatility. The study contributes to the literature on energy security under geopolitical stress and offers policy-relevant insights into resilience strategies needed to uphold SDG 7 targets during crises. |

| Abstract: | This study uses a discrete choice experiment to examine how ranchers in the Northern Great Plains respond to features of the Grassland CRP. We find that ranchers prefer higher payments and cost-share, shorter contract lengths, and flexibility. Ranchers value contracts that allow winter grazing and resist mandatory rotational grazing. Willingness-to-accept estimates show that ranchers require $6.47/acre for rotational grazing and $8.19 for longer contracts but would forgo $7.81, $11.77, and $7.84 per acre for cost-share, winter grazing, and flexibility, respectively. Preference heterogeneity is most evident for grazing-related practices and cost share. Nearly 69% of non-participants are unaware of the Program and perceive that payment and cost-share are more important than other contract features. Participation could be improved through flexible contract design, enhanced outreach, and financial incentives. |

| Abstract: | Commercial aquacufture is a viable and growing industry around the world. While there may be continuing decline in fish stocks in the inshore/coastal waters in Trinidad and Tobago, the demand for high quality fish protein continues to grow. Aquacufture has been viewed by many as a means to address the gap between seafood availability and consumer demand. This paper reports on a study, which was conducted to assess the potential of aquacufture in Trinidad and Tobago. Based on interviews with aquacufture operators, policy analysis matrices were developed for aquacufture production. For comparison policy analysis matrices were also developed for sheep and goat production based on a recent survey of the sheep and goat industry of Trinidad and Tobago. The study found that the DRC and EPC values for tilapia production, coupled with the lower cost per unit of protein compared with other sources of animal protein, indicate that tilapia production has a comparative advantage, especially as compared to sheep and goat production. The paper also discusses measures that need to be taken to unlock the potential for commercial aquaculture, mainly in the form of tilapia production in Trinidad and Tobago, to meet this country's demand for fish protein. |

| Abstract: | The value of a statistical life (VSL) is a critical driver of estimated benefits for federal policies designed to improve human health, safety, and environmental exposures. The vast majority of empiri-cal evidence on the magnitude of the VSL arises from hedonic wage models that have been plagued by measurement error and omitted variables. This paper employs randomly assigned workplace safety inspections to instrument for plant-level risks in a quasi-experimental design to address these limitations. We provide credi-ble causal evidence for the existence of compensating wages for fa-tality risks and estimate a VSL between $8 and $10 million ($2016). |

| Abstract: | Assessing ecosystem service (ES) demand remains conceptually fragmented and methodologically inconsistent in social-ecological systems (SES) research due to the lack of a framework linking human preferences to benefits derived from ES fruition. This study develops a systematic typology of ES demand assessment based on an integrative review of empirical studies. We conceptualize demand as emerging from two competing modalities: the consumption of provisioning and cultural services, which may drive ecosystem depletion, and the need for risk reduction through regulating services, which supports ecosystem preservation. Building on this distinction, we identify five valuation approaches, two that directly translate ES value into realized benefits and three that infer demand indirectly through monetary estimation, expert knowledge, or threshold-based criteria. The framework clarifies how socio-economic variables represent human preferences and needs, revealing the diversity and underlying logic of current demand assessment practices. Limitations include the lack of analysis of interactions between demand modalities, the treatment of services in isolation rather than as interdependent bundles, and the neglect of temporal and spatial dimensions. By systematizing fragmented methodologies, the framework advances understanding of ES demand and provides a structured basis for selecting appropriate demand assessment approaches across diverse SES contexts. |

| Abstract: | The spread of crop diseases poses significant challenges to the stability and location of agriculture. This paper examines how pest pressure influences the spatial patterns of crop production. Using detailed spatial data on pest infestations and crop acreage, we study the impact of Pierce’s Disease and its vector, the Glassy-Winged Sharpshooter, on the spatial patterns of grape (the target of the disease) and citrus (the host of the vector) production in California. We combine crop maps and pesticide use reports to estimate how pest outbreaks affect growers’ location decisions. Our results show that pest pressure leads to spatial avoidance behavior: grape acreage tends to decline in infested areas, and the distance between citrus and grape production increases. We also find that pest control programs mitigate some of these effects, supporting their role in stabilizing agricultural land use. These findings highlight the importance of incorporating pest dynamics into models of agricultural spatial decision-making. |

| Abstract: | La voiture électrique, essentielle à la décarbonation du transport routier, traverse aujourd'hui une phase de turbulences au sein de l'Union européenne (UE). Sa diffusion dépend encore largement des subventions publiques versées aux ménages, alors même que ces aides se tarissent en raison d'un contexte budgétaire contraint. Parallèlement, l'industrie automobile européenne est confrontée à une concurrence accrue de la part des constructeurs chinois, qui proposent des modèles électriques 20 % moins chers que leurs équivalents européens. Face à ces pressions concurrentielles, la Commission européenne a adopté, en 2024 et 2025, deux mesures destinées à renforcer la filière automobile européenne : elle a relevé les droits de douane sur les voitures électriques produites en Chine et présenté un plan d'action visant à consolider l'ensemble de la chaîne de valeur, de l'accès aux matières premières critiques à la fabrication des batteries. Parallèlement, l'assouplissement des normes d'émissions de CO2 pour les véhicules thermiques au printemps 2025, ainsi que la possible remise en question, en 2026, de l'échéance de 2035 pour la fin de la commercialisation de véhicules neufs non décarbonés, mettent en exergue la difficulté de concilier simultanément trois objectifs : assurer la transition écologique, préserver la survie industrielle du secteur automobile et soutenir le pouvoir d'achat des ménages. Ce Policy brief soutient qu'au lieu d'opter pour une stratégie de « procrastination industrielle », l'UE devrait créer un « choc d'électrification » afin de générer les volumes nécessaires aux économies d'échelle, condition essentielle pour rendre les véhicules européens plus abordables et compétitifs. Ce choc nécessiterait un ensemble d'actions coordonnées portant à la fois sur la demande et sur l'offre. Du côté des consommateurs, il s'agirait d'adapter les subventions à l'achat et à l'usage aux réalités nationales, notamment là où le coût de l'électricité constitue un frein. Pour les entreprises et les collectivités publiques, l'instauration d'une obligation d'intégrer une part minimale de véhicules électriques dans leurs flottes permettrait d'élargir rapidement le marché. Les constructeurs européens devraient également être encouragés, voire contraints, à proposer des modèles d'entrée de gamme réellement abordables. Sur le plan industriel, il est indispensable de soutenir massivement la production de batteries en Europe afin de réduire l'écart de coûts avec la Chine, tout en maintenant des droits de douane suffisants pour protéger l'écosystème automobile et favoriser la relocalisation. Cependant, ce renforcement du « Made in Europe » ne pourra se faire sans partenariats avec les constructeurs chinois, leaders mondiaux dans les technologies électriques. Il faudra néanmoins veiller à ce que ces partenariats garantissent de véritables transferts technologiques et contribuent au maintien de l'emploi en Europe. Enfin, l'ensemble de ces mesures doit s'inscrire dans une trajectoire claire, sans remise en cause des objectifs précédemment définis, afin de ne pas créer d'incertitude réglementaire, ce qui est néfaste pour les investissements et favorise les attitudes attentistes, sans permettre d'avancer sur la décarbonation du transport routier. |

| Abstract: | Agricultural Extension is the key instrument that supports agricultural development in many Caribbean countries. Through the extension process, the role of change agents is critical in interfacing with farmers in order to create new opportunities for production, a competitive base for local and international trade and a sustainable agriculture. As a result, competent extension agents are needed to make decisions and train farmers. Distance Education training can be a powerful tool to increase the competence of agents. This can be utilised for extension in-service training because it provides the benefits of lower training costs due to lack of travel requirements and the ability of agents and specialists over a large geographic region to exchange information and ideas. Responses to a self-administered questionnaire to extension agents in Trinidad and Tobago revealed that they were strongly receptive to this form of training. The questionnaire showed that there are existing resources which support the use of distance education within the environment of the extension agent. The survey goes on to show some of the perceived limitations to implementation of distance education programs within the extension service, willingness of agents to pay for the service and areas identified for further training. Information was also obtained on the present ways extension agents gather information, satisfaction of current farmer training, and factors limiting current extension efforts. From the survey it can be concluded that there is great potential for the use of distance education training of extension agents in Trinidad and Tobago. |

| Abstract: | Effective regulatory design requires an understanding of how regulatory burden affects regulated entities. Using novel data on all applications for environmental permits in five Indian states and a natural experiment, we estimate how regulatory burden of environmental permitting affects firms. Difference-in-difference estimates show that deregulation induces smaller firms to enter and increases entry. Standard data sources would miss these substantial effects, underscoring the importance of collecting data across the firm size distribution. We also use full texts of permit certificates to create novel measures of regulatory burden. Firms in industries with reduced regulations face fewer, less stringent, permit conditions. |

| Abstract: | A growing body of evidence shows that gardening can be beneficial for multiple determinants of health, including economic situation. While this has been highlighted in the case of economically vulnerable gardeners, particularly in the U.S., less is known about broader populations and other contexts. This study explores the economic dimensions of gardening among a population of collective gardeners in a major French city (Rennes), to support the integration of economic outcomes into health impact assessments. Based on field observations (n = 19), questionnaires (n = 230), and semi-structured interviews (n = 5) conducted across collective gardens in the city, the findings show that gardeners tend to be older, more educated, and more likely to have held higher-status jobs than the general population, although a considerable proportion of them had modest incomes. Despite these findings, Economic savings were not a primary motivation for gardening, and practices were not focused on maximizing yield. Gardening experience, rather than income level, was the strongest predictor of financial savings. Garden design features, such as the presence of individual plots, also influenced outcomes. Main expenses included seeds, seedlings, and equipment, especially for beginners. Tomatoes, courgettes, and green beans were the most commonly consumed produce. Overall, the estimated economic benefits were modest. These results suggest that the economic impacts of gardening are shaped by both gardeners' socio-demographic profiles and garden design. These factors should therefore be better considered when planning in garden planning and in initiatives promoting gardening. Further research would benefit from a more detailed description of gardening contexts to better assess their broader impacts. |

| Abstract: | The issues of appropriate technology are discussed within the broad framework of agricultural development. Three leading Models concerned with the role of agriculture in economic development are reviewed to determine their relevance to the Caribbean. It is concluded that, aspects of all the models had varying degrees of relevance to the Caribbean but were not comprehensive enough for Caribbean realities. Despite dissatisfaction with the generalities of the Models we identified a fundamental role for appropriate technology in rural development. Perspectives relating to the appropriateness of Technology are discussed in the context of the receiving environment, the nature of the technology and the process by which the technology is generated. It was concluded that the circumstances of the large-farm sector were sufficiently different from that of the small-farm sector so that both the nature of the technology and the process of generation for each sector should be different. The farming systems approach is considered to provide the most useful insights for developing appropriate technology for specific target groups of farmers. The systems Framework is used to indicate the role of socio-economic analysis in developing appropriate technology. |

| Abstract: | This paper studies the effects of tariff schemes on the absolute and relative emissions embodied in agricultural imports across countries and commodities. Between 2001 and 2017, shifts in the global agricultural trade structure drove an increase in emissions embodied in imports; preferential margins widened under proliferating preferential trade agreements; and reductions in agricultural import tariffs were associated with increased trade flows. Building on these patterns, we employ a structural gravity framework to quantify the general equilibrium effects of two counterfactual tariff schemes: the universal adoption of most-favored-nation (MFN) rates and a transition to global free trade. Given the significance of relative emissions embodied in trade as a critical directional indicator, the paper finds that universal MFN rates reorient agricultural sourcing toward carbon-intensive exporters, while the abolition of tariffs shifts the trade structure toward suppliers with lower emissions intensities in agricultural production. However, analysis by importers and commodities uncovers divergent outcomes. These findings suggest that tailored trade policies should account for the specific trade structure of each agricultural product and the economic status of trading partners. |

| Abstract: | Our article analyses the quality of green jobs in France, applying a definition of green jobs that has emerged in recent years to the French labour force survey – a large, representative dataset. Using regression and classification techniques, we find that green jobs are associated with lower job quality than non-green jobs, particularly for low-skilled workers, who tend to experience lower wages and reduced socio-economic security. In contrast, high-skilled workers tend to enjoy either better or not significantly different job quality relative to their non-green counterparts. Our analysis also highlights the heterogeneity of green jobs, which can be grouped into four distinct clusters with varying levels of job quality, challenging the narrative of uniformly "good green jobs". |
| Abstract: | Cet article propose une analyse de la qualité des emplois verts en France, en appliquant une définition des emplois verts apparue ces dernières années sur une base de données représentative, l'Enquête Emploi. À l'aide de régressions et de techniques de classification, nous montrons que les emplois verts présentent une qualité inférieure à celle des emplois non-verts, en particulier pour les travailleurs peu qualifiés qui bénéficient de salaires et d'une sécurité socio-économique moins élevés. Les travailleurs plus qualifiés bénéficient d'une qualité d'emploi supérieure ou similaire à celle de leurs homologues non-verts. Notre analyse révèle également l'hétérogénéité des emplois verts, répartis en quatre groupes présentant différents niveaux de qualité d'emploi, remettant ainsi en question le discours sur les « bons emplois verts ». |

| Abstract: | Huanglongbing (HLB), also known as citrus greening, is currently recognized as the most devastating disease affecting the global citrus industry. In Florida alone, HLB has caused severe declines in citrus production since it was first detected in 2005. In contrast, timely and targeted interventions in Texas still offer an opportunity to mitigate the long-term impacts of the disease. This study determines the necessary mitigation levels for achieving economically viable control strategies, employing a simulation-based optimization model. The proposed methods supports more efficient allocation of public and private research and development resources. Preliminary results suggest a set of interventions in the progression of disease incidence and severity to outperform current management practices in terms of expected net returns. These findings provide valuable benchmarks for the development and evaluation of future HLB control strategies. |

| Abstract: | The Conservation Reserve Program (CRP) is one of the most important agrienvironmental policies in the United States. Farmers and landowners retire their land into vegetation cover and receive rental payments paid by the government. Although the program generates well-documented ecosystem benefits, there are debates about its potential negative impact on the local economy. This paper studies the distributional impact of the CRP program on the local agribusiness sector. By leveraging a detailed county-level panel dataset of agricultural expenses, we use an instrumental variable (IV) approach to identify the causal impact of the CRP enrollment acreage and local agricultural expenses. We find that an additional 10% increase in the acreage of CRP enrollment reduces local agricultural expenses by about 0.175% on average. This effect is robust in most regions and expense categories. We also find regional variations in the response between the Southeast and the Midwest. |

| Abstract: | The utilization of starch as a major food ingredient has considerable significance. Trade and export of food starches has contributed to the economic growth and viability of various developing countries. The global starch market however, is highly competitive, with industry consumers opting for high quality, but affordable and steady supplies. Starch has multiple functions in food applications, most commonly as a bulking agent, binder, carrier, fatreplacer, for texture-improvement and as raw material for other starch-related products. In addition, starches can be modified to further increase their utility. Tropical root crops that are currently used as commercial starch sources include cassava (Manihot esculenta, Manihot utilissima), yam (Dioscorea spp.), cocoyam (Xanthosoma spp.), taro (Colocasia esculenta) and arrowroot (Maranta arundinacea). These crops have varying levels of starch, ranging from 19-40 %, differ in composition and consequently their properties in food products. Predominant areas of production, consumption and export are the Caribbean, Latin America, sub-Saharan Africa and Southeast Asia. The demand for food starches continues to be high in industrialized countries, where processed food consumption is high and the food industry continues to be robust and vibrant. Applicability of starch in food products is determined by various factors: its composition, functionality and cost. Root starches, which have high amylopectin levels, are highly desirable as they have great clarity, minimal flavor and suitable water absorption and swelling capacity. |

| Abstract: | We offer a unified numerical method to solve both impulse and barrier control problems in multidimensional state spaces. Our numerical approach is based on the link between optimal regime switching model and impulse and barrier control problems. This link results in a convenient representation of the optimality conditions for numerical solution methods. Using finite difference approximations for derivatives, the optimality conditions are transformed into an extended vertical linear complementarity problem which is solved using Newton type methods. The numerical approach is illustrated with several examples. |

| Abstract: | There have been concerns that Sanitary and Phytosanitary (SPS) measures can act as a barrier to trade and thus impede the export of agricultural and food products to developed countries. To a large extent, this reflects poor access to compliance resources, including scientific and technical expertise, information and finance. In 1994, developed countries collectively accounted for 72.5% of the total world imports of agricultural products (UNCTAD 1998). This paper explores the impact of the SPS Agreement on food safety and examines some developing food safety issues. The basic rules for food safety as set out by the SPS Agreement are highlighted and the standards by different regulatory and advisory bodies are outlined. Some of the problems and challenges that developing countries experience in meeting SPS standards in food safety are identified. |

| Abstract: | Efficient facility location is vital for optimizing perishable fresh produce supply chains, especially in regions with fragmented production and dense demand. This study develops a mixed-integer programming framework to identify cost-optimal food hub locations and capacities for the U.S. fresh produce supply chain, with a particular focus on the New York–New England (NY–NE) region. The model integrates spatially resolved data on production, trade, and consumption across nine food categories and applies a two-tiered resolution strategy: national-scale aggregation using Major Land Resource Areas and Grocery Marketing Areas, and county-level disaggregation within NY–NE. Results reveal a hub-and-spoke network shaped by cost efficiencies, with strategic hubs emerging in both production-heavy and consumption-dense areas. The NY–NE sub model highlights the region's heavy reliance on long-distance sourcing and the need for region-specific infrastructure planning. By linking optimization with granular flow analysis, this work advances supply chain modeling for regional food resilience and cost-effective distribution planning. |

| Abstract: | Mad Cow Disease (BSE), genetically modified organisms, greater demand for organic produce, cloning of livestock, all enjoy the increasing fear and preoccupation of EU consumers with "safe food". EU food retailers have responded by requiring greater guarantees from suppliers that all foods supplied to them for distribution, including bananas, are safe and produced in line with their declared standards of "good agricultural practice". For the Windward Islands banana industries these new standards have become as important a competitive issue as the WTO rules and continued access to the EU market under the new EU Banana Regime. I review the evolution of these new standards and the nature of the industries response to the new imperatives .and assess their impacts on and implications for the Windward Islands banana industries. |

| Abstract: | In the United States, direct marketing of farm products through farmers' markets is an important sales outlet for farmers with small- to medium-sized operations. However, in the Dominican Republic, most farmers' markets are operated by intermediaries (middle men), which limits the effectiveness of the farmers' markets as a rural economic development tool. With technical and financial support from the United States, four markets operated by farmers were established in 1999. One of the markets has ceased operating which emphasizes the importance of studying market structure and the perceptions of farmers and consumers regarding these markets. This study uses survey data to analyze the socio-economic characteristics of farmers participating in these markets, their rationale for participating, level of sales, operating characteristics and problems experienced in participating in the markets. The findings reveal that most of the farmers are small-scale producers (averaging 2 hectares) and that the farmers' markets account fora relatively large proportion of their sales. In fact, the majority of the farmers (82%) reported that they receive at least half of their total agricultural sales from farmers' markets. They also receive higher prices from direct sales to consumers at the farmers' markets versus sales to intermediaries. However, lack of credit for farmers is one problem that limits the effectiveness of the markets as a rural development strategy. The research identifies changes that are needed to ensure the sustainability of the markets, as well as, meet the needs of small farm operators. |

| Abstract: | Throughout history, innovation has driven progress and helped people address the problem of the age. This progress has not been achieved without pain and controversy, at times war and famine and pestilence thwart our best endeavors. Despite setbacks, people throughout the world continue to strive to understand the natural world, to pursue truth and beauty, and to create a better world for themselves and their children. Science has a role to play in all these pursuits. However, the very power of the new discoveries in the biological sciences raises fears that these discoveries will not be used wisely. Many believe that they will: • Accelerate the destruction of the natural environment, • Damage human health • Concentrate too much power in the hands of a few global companies • Widen the gap between the rich and the poor, within and between nations. The task of the scholars of today is to analyze where Plant Biotechnology can lead to technical innovation and how these can be used wisely: • To improve agriculture productivity, • To conserve nature resources, • To create wealth especially for poor people in developing countries. Powerful tools provided by Biotechnology in recent years have had a profound impact on the food and agriculture sector worldwide. Innovation, production and processing methods have revolutionized many traditional systems, and the world's capacity to generate food products for its growing population has evolved at an unprecedented rate. These developments have naturally been accompanied by radical changes in economic forces and social organization as well as in management of the earth's productive resources. Our very relationship with nature has been overturned by technological advances that enable us not only to determine genetic improvement through selective breeding but also to modify living organisms and create novel genetic combinations in the quest for stronger and more productive plants animals and fish. Understanding such developments invariably give rise to controversy, and arguments for and against their implementation tend to be intense and emotionally-charged. CAES: |

| Abstract: | Wildfires have become more prevalent and have negatively affected economic well-being and human health in wildfire-prone regions. Compared to other sectors, the effects of wildfires on agriculture have received less attention. In this paper, we estimate the effect of wildfires on agricultural land prices. To the extent that wildfires pose a threat to current and future farm-related returns, agricultural land prices should decrease in response to nearby wildfires. We employ a difference-in-differences research design to examine how wildfire risk, measured by proximity to wildfire, affects observed parcel-level agricultural land prices. The study uses pooled cross-sectional data covering agricultural land transactions in Oregon over the period 2000-2023. Preliminary results indicate that wildfire risk has lowered agricultural land values in Oregon by 19-54% for parcels in close proximity (within 2km) to wildfires. The findings highlight the importance of measuring the economic costs of recent catastrophic wildfires in Oregon and the western US, particularly in relation to wildfire-related damages to the agricultural sector. |

| Abstract: | Invasive species like wild pigs (WPs) inflict substantial economic losses on agricultural systems but accurately quantifying these costs is challenging due to limited data on population abundance. In the absence of data on species abundance, researchers frequently rely on species occurrence data for estimating economic impacts. We develop a conceptual model illustrating that stock dynamics lead to time-varying costs of invasions that bias occurrence-based estimates using two-way fixed effect (TWFE) methods. Then, we estimate the welfare cost to cropland agriculture of WP invasions in the southeastern US by combining more than a decade of data on the presence of WPs with land rental market and cropland data. We find that WPs cost an average of 1.6 million dollars per county per year (95% CI: $1.1 million to $2.1 million). Estimates using TWFE underestimate total costs by 21% of the unbiased estimate. The difference is driven by a 33% underestimate of impacts to cash rent with the arrival of WPs. We also provide evidence that producers adapt to WPs by planting fewer acres of corn and soy and more acres of cotton and sorghum. Our estimates support the need for targeted, effective WP elimination strategies in the US. |

| Abstract: | Trading Issues: Future of Export Agriculture — Traditional and Non-traditional Although the final version of the 2002 US Farm Bill, dubbed, The Farm Security Act of 2001, has not yet been agreed upon, on the basis of the versions submitted by the US House of Senate there are likely to be major changes to the US sugar program that will undoubtedly impact the Caribbean sugar producers. Such changes are aimed at bolstering the ailing US sugar program that is proving to be both difficult and expensive to administer in a manner that continues to provide stability to the US growers at minimum cost to the government treasury. Expanding domestic production, increasing imports and international commitments under the WTO and NAFTA have within recent years severely weakened the effectiveness of the Program and have wreaked havoc in the industry. Among the changes proposed are the following: (a) increasing the minimum level of sugar imports from 1.13 million metric tons (MMT) to 1.38; (b) providing the US Secretary of Agriculture with the discretion to adjust the loan rates; (c) requiring that the program be administered at no net cost to the Federal government; and (d) reinstating the marketing allotment for domestically grown sugar. With the use of a modified version of a World Sugar Policy Simulation Model the impacts of these likely changes on US domestic consumption and production of sugar are analyzed and implications drawn fro the CARICON-US sugar quota holders. |

| Abstract: | Over the past three decades the globalization in agri-food sector has been accompanied by a dramatic restructuring, liberalization and privatization of markets often with serious adverse consequences for small farmers in developing and transition countries. Consequently, governments and the international donor community have markedly shifted their development policies from traditional technology transfer approaches towards more market-driven approaches of linking farmers to markets. The international agricultural development literature has begun exploring the appropriate structure of third-party facilitated institutions and enforcement mechanisms to support linking small farmers to markets. Based upon a series of long-term qualitative and quantitative analyses of the instrumental case of USDA Marketing Assistance Project in Armenia, we use a grounded theory approach to develop a dual strategic model for the establishment of sustainable third party facilitated market linkages between producers and processors. Our results and model indicate that if donors pursue a dual strategy of concurrent facilitation of private enforcement on the processing level and institutional arrangement on the producer level in the design and implementation of third-party market linkage programs, they are likely to achieve higher program impact, improved trust among channel participants, and long-run economic sustainability of market linkages. |

| Abstract: | Competitiveness is important for Jamaica's agriculture and specifically sugar, as the instruments of protection are gradually being removed. Sugar producers and sugar interests in Jamaica are concerned that one day they may not benefit from the present preferential agreements for sugar sales to the European community and the United States. A new agreement reached in the year 2000 with the European Union extends Jamaica's preferential treatment to 2008. The study used two indicators namely: "Relative Quasi-tents" and Nominal Rate of Protection" to measure competitiveness. Results of this study suggests that 92% of the farms with 3.3 hectares or less of sugar realized modest quasi-rents that were only about 1.6 times the opportunity cost of owner-operator labour. The comparable figure for producers of 16 hectares of sugarcane was 7.3 times the opportunity cost of owner operator labour. Nominal rates of protection estimated here for the 1990-2000 period indicate that domestic producers have been receiving prices for sugarcane that are about two times the equivalent free market world prices. This is a result of the country's preferential marketing agreement with the European community and the United States. The study points out that Jamaica's sugarcane yields are low, the sugar content of the cane is low, production costs are high and cane ills are currently inefficient. |

| Abstract: | This paper estimates the short-run economic impacts of low-intensity typhoons—tropical storms and depressions—on local activity in Vietnam. Leveraging monthly electricity consumption data for over two million households across three coastal provinces from 2012–2022, we construct a high-resolution panel merged with typhoon track data. We exploit hyperlocal variation in typhoon exposure using a dynamic event study and a stacked difference-in-differences design, defining treatment based on proximity within 17 kilometers of a storm’s path. Results show a sharp and statistically significant decline in electricity consumption—up to 5% in the month of landfall—concentrated in areas directly hit by tropical storms. Tropical depressions exhibit smaller, noisier effects. Comparison with BRDF-corrected nighttime lights (NTL) data reveals that electricity consumption provides more reliable estimates of typhoon impacts at lower administrative levels, as NTL measures fail the parallel trends test. Our findings underscore the economic relevance of frequently overlooked, lower-intensity storms and highlight the value of granular energy data in assessing disaster-induced disruptions in developing country contexts. |

| Abstract: | We study how Argentine AgTech startups communicate sustainability on their websites and whether misalignment between symbolic and substantive actions (“greenwashing”) relates to their economic performance. We code web disclosures into symbolic and substantive actions, construct firm-level scores for each dimension, and combine them into a greenwashing measure. Using interval regressions for revenues and probit models for foreign-market concentration, we find that greenwashing is negatively and significantly associated with revenues: customers appear to penalize symbolic claims that are not backed by substantive actions. Indeed, decomposition analysis shows that greater symbolic communication reduces revenues, whereas declared substantive actions have no statistically discernible effect. On the other hand, the relationship between the revenues and the level of greenwashing is non-linear—small amounts of greenwashing induce positive effects on revenues but these turn negative as greenwashing rises—and is heterogeneous by firm age: younger startups are more strongly penalized, consistent with reputational mechanisms. By contrast, stronger symbolic communication increases the likelihood that AgTech firms concentrate sales in foreign markets. Overall, the results underscore the economic costs of misaligned sustainability communication and the value of credible, action-based disclosure. |

| Abstract: | In the context of modern globalisation, peripheral economies are affected not only by international real business cycles but also by the financial dynamics of advanced economies. This adds to each economy's internal and structural features, creating complexities and interrelationships between domestic and external actors. Stock-flow consistent (SFC) models attempt to close existing methodological gaps in macroeconomic modelling, analysing economies' real and financial spheres in an integrated way. This chapter describes the process of adapting and calibrating an SFC model in continuous time for the Colombian economy. It presents a detailed account of the empirical macroeconomic model developed, capturing most of the country's institutional characteristics. The primary objective of this model is to function as an analytical tool and support mechanism for a wide range of academic and policy debates, as demonstrated in subsequent chapters. |

| Abstract: | Discrete choice experiments (DCEs) are widely used to elicit consumer preferences, yet how the assignment of attributes and levels affects respondent understanding and preference elicitation remains underexplored. Although prior studies have examined different DCE design factors, little attention has been given to the implications of swapping attributes and levels. This study aims to fill this gap by comparing two designs that reverse the roles of attributes and levels. Our results find that the design using sustainability measures as attributes improves reading ease compared to the design using sustainability outcomes as attributes. Moreover, while both designs show consistent preference patterns across choice sets, variations in willingness-to-pay (WTP) estimates suggest differences in preference consistency between the two designs. These findings highlight that attribute-level assignment may have implications for both respondent and researchers. |

| Abstract: | The JBPA private sector loan programme to Small Banana Farmers, jointly financed with the Jamaica Agricultural Development Foundation (JADF) provided practical lessons about the planning and operation of agricultural credit programmes. Success was linked to an independent extension service and rigid farmer selection criteria with extensive credit checks. Problems with land tenure needed creative solutions. All farmers were required to attend orientation meetings prior to signing loan documents. Loan disbursements were inputs rather than cash, with delivery at farmgate. Repayment was through point of sale deduction order, and sales were closely monitored to detect delinquents. Major problems were encountered with Hurricane Gilbert, and with farmer laxity when disbursements and transport of inputs ceased. |

| Abstract: | Local production of Poultry products in St. Lucia is uncompetitive. However, the industry does have the potential to contribute meaningfully to, amongst other things, Gross Domestic Product and employment. An comparison of the cost of producing broiler meat in St Lucia with producing it in Trinidad and Tobago enables the identification of key cost disadvantages, such as feed and packaging costs, which, if improved, could enhance the competitiveness of the local industry significantly. St. Lucia remains generally uncompetitive with regards to imports from the USA even after adjustment for cost disadvantages. However, the competitive position as was indicated by the Nominal Protection Coefficient (NPC), improved significantly vis-à-vis imports of broiler products from Trinidad and Tobago after adjustments for cost disadvantages were made. The recommendations include improving plant capacity utilisation, the procurement of packaging materials, feed and chicks from cheaper sources and at bulk rates. The development of pluck shops would reduce significant costs such as electricity. Recommendations also included policies changes such as the removal of the current 20% import regime, the commissioning of a study to determine the optimum market structure of the broiler industry, and the development of niche marketing strategies. |

| Abstract: | Regional cooperation in agricultural production and marketing has been accepted by Commonwealth Caribbean Governments as an essential and desirable objective in the movement towards closer economic integration. In the five years of Carifta, a considerable measure of regional cooperation has been achieved through the growth of intra-regional trade in both manufactured and certain agricultural commodities. In the case of trade in the latter, much of this has been conducted under the Agricultural Marketing Protocol (AMP) which forms an integral part of the Carifta Agreement and is the principal instrument outlining any form of agricultural policy. The Protocol is essentially a marketing Agreement and makes no provision for regulating agricultural production among Carifta Member States. It has been recognised by Carifta Governments that while the provisions for marketing contained in the AMP are necessary in themselves, they are insufficient to achieve the long-term goals for the development of agriculture and trade in the Region and a satisfactory redistribution of benefits among all Member Territories. In fact, in the five-year history of Carifta trade and production have tended to polarise in favour of the More Developed Countries, a consequence thought largely due to differences in resource endowment. The Carifta Governments have endorsed rationalisation of agriculture as an appropriate strategy for working towards closer regional cooperation in agricultural production and marketing. Rationalisation is conceived as a means of achieving certain levels of national specialisation in agricultural production and optimising the use of national and regional resources. An important and immediate aim of rationalizing agricultural production in the region would be to reduce the current degree of duplication and competition in agricultural activities and to work towards the achievement of greater complementarity among national agricultural programmes. In the Caribbean the concept of rationalisation of agriculture is without precedence and this is equally true for the application of such an approach in a regional economic grouping. National political considerations together with the current efforts of Member Governments, independently and insularly, to expand and diversify their economic activities add to the difficulties of accepting, let alone applying such an untried approach to agricultural development in the Region. This paper discusses the current efforts in Carifta to promote closer cooperation in agricultural production and marketing and some of the problems inherent in developing such a strategy. The possible benefits to individual Member Territories and to the Region as a whole require no further elaboration. There are existing areas of cooperation both in production and marketing which clearly demonstrate some of the potential benefits and these will be examined briefly. Finally, the point is emphasised that any approach to regional cooperation in agriculture -- and this is equally true for other areas of activities -- cannot be based solely on economic considerations such as would be determined by comparative advantage criteria. Given the common historical experiences and current agricultural activities, the national aspirations, the similarities in the physical and climatic conditions in the Region, cooperation in agriculture will depend, in the final analysis, on political considerations and the degree of commitment to regional integration. |

| Abstract: | Hydroponic systems constitute a growing segment of U.S. vegetable production, offering advantages in input efficiency and year-round cultivation. This paper develops a two-stage analytical framework to examine the determinants of hydroponics adoption and to quantify its prospective market-level implications. In the first stage, two theoretically grounded approximate measures—area-based and operation-based adoption rates—are constructed using publicly available data from USDA NASS, PRISM, EIA, and the U.S. Census. A random forest model is employed to identify key predictors and forecast state-level adoption through 2024. The results highlight distinct adoption mechanisms shaped by demographic, economic, and environmental factors. In the second stage, the predicted adoption rates are incorporated into a partial equilibrium supply model accounting for technological heterogeneity. Simulations estimate the effects on aggregate supply and producer surplus. The framework offers a novel approach for linking technology diffusion with market-level welfare analysis. |

| Abstract: | The sugar industry of Belize is faced with challenges from within and without. Trade liberalization and policy adjustment measures, on the international front, brought increased pressures on the preferential markets for sugar affecting both volume and price levels. The internal challenges are related to a poor organizational framework, outdated legislation, low productivity and efficiency of sugarcane production, harvesting and delivery, a high level of indebtedness and an associated low level of investment. The paper will present the status of the sugar industry of Belize, the rationale for the modernization of the sugar industry, the steps being taken to modernize the sugar industry and the implications of the modernization process for the sugar sector and the economy of Belize. There is an urgent need to drastically restructure the industry in order to make it more competitive and to ensure its growth and survival as a solid economic pillar in Belize's development. |

| Abstract: | At the World Food Summit in 1996, 186 countries including those of CAR1COM adopted the "Rome Declaration", which among other things expressed the: "Commitment to achieving food security for all and to an ongoing effort to eradicate hunger in all countries, with an immediate view to reducing the number of undernourished people to half their present level no later than 2015". The number of such persons was then estimated at 840 million and the target of 400 million persons was set for 2015. Five years later the Summit recently re-convened in (June 2002) to evaluate the progress or lack of it in meeting this target. Despite the unprecedented character of these conferences and the undoubted political weight attached to them, they have barely found echoes in public debates in the Caribbean. This paper explores issues of food security as they concern the Region. It does so from two vantage points namely, (1) by reconnoitering global efforts and targets aimed at reducing food insecurity and (2) by drawing attention to the prevailing conditions and policy responses to agricultural decline and stagnation along with the persistence of strong pockets of poverty, high levels of inequality and the consequent impact on the state of hunger, nutrition, and food insecurity. |

| Abstract: | Con ciertas prevenciones, no exentas de temores, tengo la audacia de escribir estas líneas polémicas, controversiales, contra la corriente más habitual en que nos movemos: la búsqueda del crecimiento sin más. Este artículo aborda la cuestión del crecimiento económico como una meta en sí misma, desde una perspectiva al estilo de los Clásicos, esto es desde la “filosofía social”. La noción de crecimiento económico ilimitado ha dominado el discurso económico y político durante décadas. Sin embargo, este trabajo sostiene que esta perspectiva es muy cuestionable y debería ser reexaminada. Keynes se preguntaba, desde una visión ética, que si el crecimiento es un medio para conseguir un fin ¿Cuál es éste? ¿Y cuánto crecimiento es bastante? Se cuestiona la relación entre crecimiento económico y “calidad de vida” (bienestar humano), y se exploran las consecuencias sociales y ambientales de un modelo de desarrollo basado en el crecimiento ilimitado. Se señala la distinción entre la escasez relativa de Ricardo, salvable por el sistema de precios, y la escasez de Malthus o escasez absoluta, insuperable vía los precios relativos por la sencilla razón de que la naturaleza es finita. ¿Estaremos frente a la gran “trampa del progreso”? A través de un análisis crítico de los costos presentes en el proceso de crecimiento, se argumenta a favor de un modelo económico alternativo que hace uso del concepto de "estado estacionario selectivo". Este modelo busca conciliar el progreso social con la preservación de los recursos, al limitar el crecimiento económico en ciertas áreas y promoverlo en otras. Se exploran las implicaciones de esta propuesta y se discuten algunos aspectos que se encuentran en la historia del pensamiento así como el cruce de miradas con otras disciplinas. Si bien, esto más que una propuesta representa una protesta y una exhortación a la cautela respecto al rumbo que estamos siguiendo actualmente. |
