| Abstract: | India's development story is considered a conundrum. Recent economic developments have not matched the parallel development in the food security front of the nation. Agriculture and food security are interlinked. Without sustainable agriculture and allied sector development, zero hunger by 2030 can't be achieved. About 21.9% of the population is recorded below the poverty line. The percentage of the undernourished population was recorded in the downward direction, but still, 14% of the population is facing undernourishment. The study's findings further revealed 17.5% and 34.7% wasting and stunting among children under five years of age, which were caused by the absence of the required nutritional level of food. The mortality rate of children under five years of age registered a decline, i.e. from 5.2% in 2012 to 3.7% in 2020. The results of the analysis with respect to agricultural production revealed positive growth in the production of cereals, coarse cereals, pulses, fruits and vegetables and livestock products such as milk, eggs and meat during the period under investigation. India produced food items like cereals & millet, fruits, sugar, milk and eggs much more than the nation’s requirement except pulses, vegetables, and meat. Despite this, the problems of food insecurity and malnutrition persisted in the nation. The difference in food intake might be due to constraints in food distribution at regional and local levels and household-specific economic and non-economic factors. Over the last few years, the government has made significant efforts by launching various policies targeting food security, nutrition support, housing for all with basic amenities, education for all, universal health coverage, road connectivity, social security, employment, livelihood diversification, skill development, etc. for the overall development of the deprived and economically backward section of society. Bridging the deprivation gap is still a challenging task for the nation. |

| Abstract: | The environmental gains of dietary change are often assessed in relation to average national diets, overlooking differences in individual consumption habits and preferences. As a result, we ignore the roles and impacts of different consumer groups in a sustainable dietary transition. This study combines micro data on food intake and consumer behaviour to elicit the likely environmental gains of dietary shifts. We focus on the Netherlands owing to the county’s ambition to halve its dietary footprint by 2050. Linking food recall survey data from a cross-section of the population (n=4, 313), life cycle inventory analysis for 220 food products, and behavioural survey data (n=1, 233), we estimate the dietary footprints of consumer groups across water, land, biodiversity and greenhouse gas footprints. We find that meat and dairy significantly contribute to the dietary greenhouse gas (GHG) footprint (59%), land footprint (55%), and biodiversity footprint (57%) of all consumer groups, and that male consumers impose a 30-32% greater burden than women across these impact areas. Our scenario analysis reveals that simply replacing cow milk with soy milk could reduce the GHG, land and biodiversity footprints of food consumption by ±8% if widely adopted by the Dutch adult population. These impacts could be further reduced by ±20% from a full adoption of a sustainable diet, as recommended by the EAT-Lancet Commission, but would significantly increase the blue water footprint of Dutch food consumption. While the EAT-Lancet recommended diet is preferred in terms of impacts and nutrition, it would necessitate a complete overhaul of individual dietary habits, whereas shifting to soy milk is a simple single product substitution and a more accessible choice for consumers. However, when incorporating gender- and age-specific willingness for meat and dairy consumption reduction, the environmental gains resulting from partial adoption of the EAT diet and No-Milk diet diminish to a mere ±4.5% and ±0.8%, respectively. Consequently, consumer motivation alone is insufficient to realise the significant environmental gains often promised by dietary change. Our findings highlight that specific and targeted policies are needed to overcome the barriers that consumers face to adopting a more sustainable diet. |

| Abstract: | Land reforms have been reported to impact agriculture, economic performances and indicators of countries along with water users and allocations. However, little is known about how land fragmentation (consolidation) in land-reform processes affects water availability. This research investigates a question “how the number of water users is related with irrigation water allocation in land reforms, †hypothesizing that an increase in the number of water users through land fragmentation poses negative threats on the water allocation through a mediation of irrigation types. We conduct empirical analyses for irrigation water demand and availability, utilizing panel data for 25 years from 13 districts in Sugd province, Tajikistan. Two main results are obtained: First, the irrigated areas are main drivers that increase irrigation water demand in comparison to any other factors, and the impact by pump irrigated areas is approximately 1.6 times as large as that by gravity irrigated areas. Second, the increasing number of water users under land fragmentation in Tajikistan tends to reduce irrigation water availability, and the magnitude in reduction under pump irrigation is more significant than that under gravity irrigation. Overall, this research establishes that irrigations and the number of water users through land reforms matter for a change in the water allocation, and the interactions particularly pose the idiosyncratic threats on the irrigation water availability. Thus, it is advisable to reconsider ongoing land-reform policies considering possible negative externality of land fragmentation as well as irrigation for food security and water sustainability in agriculture. |

| Abstract: | Based on statistical data produced by several competent organizations, this article discusses, first, the evolution of sales of organic food products and the weight they represent in the overall food market. Representing 6.3% of the French food market in 2021 compared to 3.2% in 2015, organic products have enjoyed strong growth in recent years. Since 2021, however, the market has been facing many difficulties, mainly due to inflation, which is leading consumers to make new trade-offs in their purchasing actions. In a second step, this article focuses on French organic animal products, which will represent a little less than a quarter of organic food purchases in 2021. Organic livestock products are marketed for the most part through mass distribution channels and are not very concerned by foreign trade. Thus, contrary to other organic sectors (including fruit and vegetables), domestic consumption is almost exclusively assured by products from the national market. If the consumption of organic animal products has developed, at least until very recently (2021), there is however strong competition with other signs and quality labels (Label Rouge, AOP, IGP, CCP, etc.). In France, the share of organic production in total agricultural production (expressed in tonnage) is increasing, but it varies according to the sector. Eggs rank first on this criterion (15.4% of national production), ahead of dairy products (5.2% of cow's milk collection) and, further behind, meats, particularly pork and poultry (between 1% and 2% of slaughterings). |

| Abstract: | Fruits & vegetable value chains (F&V VC) in Nigeria hold significant potential to continue toward sustainable, inclusive food system transformation. Domestic food system growth, including that of F&V, remains crucial in achieving a healthy food environment and serving as a source of various micronutrients. There is a need for bundles of innovations to address multiple challenges along F&V VC in Nigeria, characterized by a set of challenges that are unique to developing countries and F&V. V&F VC consists of many small actors, farmers, and traders, whereby limited vertical coordination can lead to significant efficiency loss along the value chain. Seasonal and temporal variations in supply-demand gaps for F&V commodities are substantial, and considerable scope exists for reducing losses and enhancing the overall efficiency of the domestic F&V sector. Policy environments are also favorable for such efforts, as the latest Agricultural Policy documents highlight the Nigerian government’s interest in modernizing F&V VC. Given the significant involvement of women and youths in the sector, F&V VC development has substantial potential to contribute to Nigeria's inclusive development of agrifood systems. The current domestic F&V VC in Nigeria suffers from various sets of problems. Access to quality seeds is limited due to the significant use of recycled seeds, limited supply, and high costs of certified seeds. Cooling practices are inefficient due to insufficient access to the grid and off-grid electricity, limited knowledge of intermediate cooling methods applicable at the farm gate, and constraining quality preservations at farm gate storage, during transportation, and storage at market premises. Processing is insufficient due to the high costs of processing equipment and limited knowledge of the construction and operation of simpler, less resource-dependent processing facilities, including drying of F&V commodities. Inappropriate packing, such as the use of Rafia baskets instead of Reusable Plastic Crates, which are commonly recognized, is still prevalent, potentially due to limited market coordination. Based on the stakeholder consultations, desk reviews, validation workshops, and availability of external resources, we identified the following as critical interventions to pilot various innovation bundles. Intervention #1 provides improved varieties and quality seeds, combined with agronomy training and certification, in northern Nigeria through the collaboration with East West Seeds and Wageningen University & Research. Intervention #2 provides off-grid cooling and cool transportation, including forced-air evaporative cooling units at farm clusters and the combination of small and large refrigerated trucks for local and longer-distance transportation, through the collaboration with ColdHubs and MIT-Lab. Intervention #3 introduces improved solar dryers and provides training on appropriate, hygienic processing methods, building, and utilization of these driers (possibly combined with the introduction of a business model), through the collaboration with World Vegetable Center and Nigerian Stored Products Research Institute. Intervention #4 provides plastic crates using various rental arrangements and improves market access for farmers through collaboration with private companies, including Bunkasa. Intervention #5 supplements interventions #1, #2, and #3 and provides improved information through certification and labeling. Lastly, Intervention #6 strengthens linkages between existing solar powered cold storages to supplement other interventions. |

| Abstract: | Aesthetic enjoyment and landscape beauty are increasingly recognized as significant attributes of cultural landscapes. Agriculture is an important integral part of the cultural landscape in many places. To date, however, there has been little research into the visual quality of agricultural landscapes - particularly of farm buildings. Consequently, this qualitative study focuses on local residents' emotional reactions to the visual impact of dairy barns as well as their subjective perceptions. The interviewees in the present study looked at various images of different dairy barn designs and dairy barns embedded in the landscape. The dairy barns shown were based on real-life dairy barns in the German agricultural region of Osnabrück in northwestern Germany. All 16 interviewees lived in the region at the time the study was conducted. The interviewees answered a questionnaire to reflect their perceptions and thoughts on the dairy barns. The evaluation shows that the quality of the landscape aesthetics of dairy farms is of importance to the interviewees. Being able to see cattle is one of the key factors contributing to a positive assessment of the landscape aesthetic quality of a dairy farm. Furthermore, this study shows that visual messages have a wide influence on the general perception of a farm. In fact, the analysis of the interviews conducted shows how numerous interpretations of how a farm is run can be derived from visual perception. |

| Abstract: | Financial incentives are provided by governments to encourage the plantation of new woodland to increase habitat, biodiversity, carbon sequestration, and other economic benefits for landowners. Whilst these are largely positive effects, it is worth considering that greater biodiversity and presence of wildlife species in proximity to agricultural holdings may pose a risk of disease transmission between wildlife and livestock. Wildlife transmission and the provision of a reservoir for infectious disease is particularly important in the transmission dynamics of bovine tuberculosis. In this paper we develop an economic model for changing land use due to forestry subsidies. We use this asses the impact on wild deer populations in the newly created woodland areas and the emergent infectious disease risk arising from the proximity of new and existing wild deer populations and existing cattle holdings. We consider an area in the South-West of Scotland, having existing woodland, deer populations, and extensive and diverse cattle farm holdings. In this area we find that, with a varying level of subsidy and plausible new woodland creation, the contact risk between areas of wild deer and cattle increases between 26% and 35% over the contact risk present with zero subsidy. This model provides a foundation for extending to larger regions and for examining potential risk mitigation strategies, for example the targeting of subsidy in low risk areas or provisioning for buffer zones between woodland and agricultural holdings. |

| Abstract: | This research explores climate change adaptation practices, strategies and policies implemented internationally that could be adopted to support the sustainable development of cities and towns across Australia. Adaptation strategies focus on reducing the impact of climate change effects while promoting sustainable development. Adaptation is framed as a shared responsibility between governments at all levels, businesses, communities and individuals. Within this overarching framework, each level of government has a specific role. Australia lacks a strong overarching direction in climate change adaptation, including legislation and funding. In a 2019 assessment of adaptation plans for 54 countries, Australia was the lowest performer. This poor performance can be linked to the narrow scope of Australia's approach to adaptation, including the lack of political leadership and the division of powers and allocation of responsibilities in the three tiers of government. The research interrogated urban adaption strategies in three international case studies and found all three case studies emphasise active community participation and leadership in devising and delivering their adaption strategies. The research found that Australian cities and towns should incorporate three main strategic approaches for effective climate change adaptation: long-term investment and holistic approaches building community resilience to deal with the impacts of climate change innovation in structural solutions that respect and reinforce the local ecological system as a way to build resilience. |

| Abstract: | Recent studies have shown the importance of relationships with nature, emotions felt, forms of attachment, and experience of nature on conservation motivations. They have proposed characterizing relational values based on these complex interactions with ecosystems. We analyzed these links for ecosystem services (ESs) associated with fish farming ponds. The analysis was based on an online survey conducted on mainland France. We identified the types of pro-environmental profiles and investigated the determinants of pro-environmental behaviors. We analyzed the types of services prioritized according to individual profiles and the factors determining sensitivity. We distinguish between individual ESs that are more hedonic in nature, and regulating or heritage cultural ESs that refer to collective motivations rather linked to eudaimonic well-being. The results highlight the importance of factors related to eudaimonic well-being, which help integrate the role of ethical values and commitment to conservation. The modeling shows little influence of the usual sociodemographic variables and the strong significance of variables considering the knowledge and familiarity with these ecosystems and the pro-environment commitment, which refers to eudaimonic well-being. These results allow us to discuss the specificities of awareness-raising policies, which imply a rationale for active citizenship. |

| Abstract: | Agricultural production has experienced radical transformation over the last few decades: specialization of enterprises, concentration within ever-larger companies, industrialization of production processes and intensification of resource use. However, these developments in agricultural production mask differences between sectors. How has the sectoral evolution of agricultural production shaped Quebec's territories? In a CIRANO study (Royer et al. 2023), the authors analyze the spatial dynamics of the bio-food sector over more than five decades, and identify the main factors behind these dynamics. This is the first study to examine the links between spatial dynamics and sectoral evolution in agriculture. La production agricole a subi de profondes transformations au cours des dernières décennies : spécialisation des entreprises, concentration au sein d’entreprises de plus en plus grandes, industrialisation des processus de production et intensification de l’usage des ressources. Toutefois, ces évolutions dans la production agricole masquent des différences entre les secteurs. Comment l’évolution sectorielle des productions agricoles a-t-elle façonné les territoires du Québec ? Dans une étude CIRANO (Royer et al. 2023), les auteurs analysent les dynamiques spatiales du secteur bioalimentaire sur plus de cinq décennies et identifient les principaux facteurs qui expliquent ces dynamiques. Il s’agit de la première étude qui examine les liens entre dynamiques spatiales et évolution sectorielle de l’agriculture. |

| Abstract: | We offer an updated and comprehensive review of recent studies on the impact of climate change, particularly global warming, on poverty and inequality, paying special attention to data sources as well as empirical methods. While studies consistently find negative impacts of higher temperature on poverty across different geographical regions, with higher vulnerability especially in poorer Sub-Saharan Africa, there is inclusive evidence on climate change impacts on inequality. Further analyzing a recently constructed global database at the subnational unit level derived from official national household income and consumption surveys, we find that temperature change has larger impacts in the short term and more impacts on chronic poverty than transient poverty. The results are robust to different model specifications and measures of chronic poverty and are more pronounced for poorer countries. Our findings offer relevant inputs into current efforts to fight climate change. |

| Abstract: | The world has pledged to protect 30 percent of its land and waters by 2030 to halt the rapid deterioration of critical ecosystems. We summarize the state of knowledge about the impacts of protected area policies, with a focus on deforestation and vegetation cover. We discuss critical issues around data and measurement, identify the most commonly-used empirical methods, and summarize empirical evidence across multiple regions of the world. In most cases, protection has had at most a modest impact on forest cover, with stronger effects in areas that face pressure of economic development. We then identify several open areas for research to advance our understanding of the effectiveness of protected area policies: the use of promising recent econometric advancements, shifting focus to direct measures of biodiversity, filling the knowledge gap on the effect of protected area policy in advanced economies, investigating the long-run impacts of protection, and understanding its equilibrium effects. |

| Abstract: | The European Union (EU) Green Deal and its Farm to Fork Strategy are intended to promote sustainable food systems to achieve EU climate-neutrality by 2050. The Farm to Fork action plan also foresees the introduction of a harmonized mandatory front-of-pack nutrition labelling scheme in 2023. The EU countries have yet to reach agreement on the nutrition labelling scheme, which will also have environmental impacts. This article raises the question of whether at the European level, countries should seek agreements on both climate mitigation and nutrition policies (full agreement as in the case of the Green Deal) or should negotiate separate climate and nutrition policy agreements (as for the nutritional labelling). To address this question, this paper develops a game-theoretic model with multiple countries where each country implements a climate policy and a nutrition policy, We compare the consequences in terms of total emissions, the level of the nutrition policy and the welfare under different institutional arrangements of a non-cooperative equilibrium, full agreement, and three alternative agreements. Our results show in particular that full agreement always leads to the lowest total emissions at the expense of the level of nutrition policy in some cases. In an extension of our analysis, we show that agreements that include cooperation over nutrition policies do not necessarily imply formation of a larger coalition of signatory countries, even if a nutrition policy has positive or negative impacts on emissions. |
| Abstract: | Le Green Deal de l'Union européenne (UE) et sa stratégie "de la ferme à la fourchette" visent à promouvoir des systèmes alimentaires durables afin d'atteindre la neutralité climatique de l'UE d'ici 2050. Le plan d'action "De la ferme à la fourchette" prévoit également l'introduction d'un système obligatoire harmonisé d'étiquetage nutritionnel sur les emballages des produits en 2023. Les pays de l'UE doivent encore parvenir à un accord sur ce système d'étiquetage nutritionnel, qui aura également des répercussions sur l'environnement. Cet article soulève la question de savoir si, au niveau européen, les pays devraient chercher à conclure des accords sur les politiques d'atténuation du changement climatique et les politiques nutritionnelles (accord complet comme dans le cas du Green Deal) ou s'ils devraient négocier des accords distincts sur les politiques climatiques et nutritionnelles (comme dans le cas de l'étiquetage nutritionnel). Nous comparons les conséquences en termes d'émissions totales, le niveau de la politique nutritionnelle et du bien-être des différents arrangements institutionnels d'un équilibre non coopératif, d'un accord complet et de trois accords alternatifs. Nos résultats montrent en particulier que l'accord complet conduit toujours aux émissions totales les plus faibles, au détriment du niveau de la politique nutritionnelle dans certains cas. Dans une extension de notre analyse, nous montrons que les accords qui incluent une coopération sur les politiques nutritionnelles n'impliquent pas nécessairement la formation d'une plus grande coalition de pays signataires, même si une politique nutritionnelle a des impacts positifs ou négatifs sur les émissions. |

| Abstract: | This paper presents innovative practices for the regionalized estimation and structural analysis of specific costs for wheat, based on the European Farm Accountancy Data Network (FADN). When implementing public policies, it is necessary to generate not only the central estimates of the distribution of the parameter of interest but also its lower or upper quantiles to select appropriate regulatory thresholds. By considering the individual heterogeneity and asymmetry of farm specific costs, this paper introduces methodologies for estimating specific costs in conditional quantiles, dual estimations of gross margins and pseudo-barycentric imputations of partial estimates. The projection of additional elements on factorial graphs allows analyzing changes of scale, from national to regional or structural, by carrying out a comparative study of the results. In order to test its relevance, this innovative procedure is applied to the estimation and analysis of specific costs and gross margins for the regions of the main wheat producing countries in the European Union based on the FADN in 2006. |
| Abstract: | Cet article présente des pratiques innovantes d'estimation régionalisée et d'analyse structurelle des coûts spécifiques pour le blé, basées sur le Réseau d'information comptable agricole européen (RICA). Dans la conduite des politiques publiques, il est nécessaire de générer non seulement les estimations centrales de la distribution du paramètre d'intérêt mais également les quantiles inférieurs ou supérieurs pour sélectionner des seuils de régulation appropriés. Prenant en compte l'hétérogénéité individuelle et l'asymétrie des charges spécifiques des exploitations agricoles, l'article introduit les méthodologies d'estimation des coûts spécifiques en quantiles conditionnels, l'estimation duale des marges brutes et l'imputation pseudo-barycentrique des estimations partielles. L'analyse confirmatoire est conduite à partir d'analyses factorielles et de classifications non supervisées La mise en éléments supplémentaires sur graphiques factoriels permet une analyse des changements d'échelle, du national au régional ou au structurel, par l'étude comparative des résultats statistiques. La projection cartographique au niveau régional des référentiels typologiques ainsi constitués permet d'en éprouver la pertinence économique. Cette procédure innovante est appliquée à l'analyse des coûts spécifiques et des marges brutes pour les régions des principaux pays producteurs de blé dans l'Union européenne sur la base du RICA en 2006. |

| Abstract: | Many community organizations provide services similar to government programs, but there is limited evidence how increased government assistance affects the use of charitable services. We examine how greater access to federal nutritional aid through schoolwide free meal programs affects food bank use across the US’s largest food bank network. We find that a 10% increase in free school meal access reduces food bank utilization by 0.9-1.4%, without significantly reducing the amount of charitable resources available. The reduction of food bank use is only found in areas where relatively few students qualified for government aid prior to universal meals. |

| Abstract: | The impacts of climate change will depend on how human societies adapt to higher temperatures, but adaptation is very difficult to measure and typically not accounted for in estimates of the costs of climate change. Here, we study whether people living in warmer countries prefer higher temperatures for their recreational outdoor activities. To do so, we examine a unique dataset of mobile phone usage in parks and similar places covering two and a half years and more than 5000 locations across 130 countries. We first exploit quasi-random variation in weather from one day to the next to derive country-specific dose-response functions and then identify country-specific temperature levels at which outdoor activity peaks. In a second step, we regress these locally optimal temperatures on the annual mean climate. Our results point to substantial but only partial adaptation to average climatic conditions. For every degree Celsius increase in mean temperature, the optimal temperature for outdoor activity increases by about 0.45 degrees Celsius. Ignoring adaptation biases projections of future changes, which we illustrate with simulations. |

| Abstract: | In the present study, we use an experimental setting to explore the effects of sugar-free labels on the willingness to pay for food products. In our experiment, participants placed bids for sugar-containing and analogous sugar-free products in a Becker-deGroot-Marschak auction to determine the willingness to pay. Additionally, they rated each product on the level of perceived healthiness, sweetness, tastiness and familiarity with the product. We then used structural equation modelling to estimate the direct, indirect and total effect of the label on the willingness to pay. The results suggest that sugar-free labels significantly increase the willingness to pay due to the perception of sugar-free products as healthier than sugar-containing ones. However, this positive effect is overridden by a significant decrease in perceived sweetness (and hence, tastiness) of products labelled as sugar-free compared to sugar-containing products. As in our sample, healthiness and tastiness are positively related, while healthiness and sweetness are related negatively, these results suggest that it is health-sweetness rather than health-tastiness tradeoff that decreases the efficiency of the sugar-free labelling in nudging consumers towards healthier options. |

| Abstract: | The concept of Sustainable Supply Chain Management (SSCM) has gained increasing recognition as organizations strive to align their operations with environmental and social responsibility. This paper explores the critical role of SSCM in enhancing sustainability across supply chains, with a focus on minimizing environmental impacts, fostering ethical labor practices, and promoting responsible sourcing. As businesses face growing pressures to operate in an environmentally and socially responsible manner, SSCM emerges as a strategic framework to achieve these goals. Through an analysis of best practices, case studies, and emerging trends, this research seeks to shed light on the evolution of SSCM, its impact on businesses, and the future prospects it holds for fostering sustainability in global supply chains. |

| Abstract: | Interest in wine generates a general culture about the terroir and the traditions associated with it, which can be called oenoculturality. A quantitative study of a sample of 1126 potential buyers of new wine was conducted in the Spanish region of La Rioja. The cognitive-affective-normative (CAN) model used allowed for the emergence of three market segments: oenoculturalists, inter-oenoculturalists and a-oenoculturalists. These results help to clarify the importance of wine culture in the acceptance of a product innovation and contribute to the identification of new market segments, which allows marketing actions to be considered. |
| Abstract: | L'intérêt pour le vin génère une culture générale concernant le terroir et les traditions qui lui sont liées, ce qui peut être dénommé œno-culturalité. Une étude quantitative auprès d'un échantillon de 1126 acheteurs potentiels de nouveau vin a été menée dans la région espagnole de La Rioja. Le modèle cognitif-affectif-normatif (CAN) mobilisé permet de faire émerger trois segments de marché : les œno-culturalistes, les inter-œno-culturalistes et les a-œno-culturalistes. Ces résultats contribuent à clarifier l'importance de la culture du vin dans l'acceptation d'une innovation produit et contribuent à identifier de nouveaux segments de marché, ce qui permet d'envisager des actions marketing. |

| Abstract: | Economists have been advocating for a land tax rather than a reg- ular property tax. There are, however, several challenges to value land for tax purposes. Indeed, data on vacant land transactions are scarce, land and structure are conventionally traded in a bundle and it is hard to capture all factors that determine the value of land. We propose to use a new Bayesian spatial model and apply the model to the uni- verse of vacant and improved land sales from Belgium in 2018. Our results indicate that vacant land prices are substantially more difficult to predict than house prices. However, the predictive performance of the spatial model improves considerably in comparison to a regular linear hedonic approach. Models that combine data from vacant and improved land are unable to improve the predictive accuracy. |

| Abstract: | Although consumers are increasingly willing to pay for the environment, the private provision of public goods from the consumption of green goods remains limited. We propose in this paper to exploit an additional private attribute of green goods, the health benefits, in order to increase the provision of public good. Health can be seen as a positive internality associated with the consumption of some green goods. We show that correcting this internality by offering labels describing these health benefits can increase the supply of public goods. The level of public good remains underprovided from the perspective of a social planner, but, under certain conditions, may equalize or exceed the optimal level of the public good from the perspective of an environmental agency. A simulation is performed to illustrate the impact of consumer preferences on the provisioning of public good at market equilibrium. |
