    Abstract: Nearly all Agri-Environmental Schemes (AES) offer farmers stable annual payments over the duration of the contract. Yet AES are often intended to be a transition tool, thus decreasing payment sequences would appear particularly attractive for farmers. The standard discounted utility model supports this notion by predicting that individuals will prefer a decreasing sequence of payments if the total sum of outcomes is constant. Nevertheless, the literature shows that numerous mechanisms, such as increasing productivity, anticipatory pleasure and loss aversion can incline farmers to favor an increasing sequence of payments. To understand what drives farmers' preferences for different payment sequences, we propose a review of the mechanisms highlighted by the literature in psychology and economics. We then analyze farmers' preferences for stable, increasing or decreasing payments through a choice experiment (CE) survey of 123 French farmers, about 15% of those contacted. Overall, farmers do not present a clear willingness to depart from the usual stable payments. Moreover, we find a significant aversion to decreasing payments in farmers with a lower discount rate and in those more willing to take risks than the median farmer, contradicting the discounted utility model.

    Abstract: Although animal agriculture is critical to the subsistence of smallholders in some poor countries, the global detrimental impact of animal farming is now both well documented and overwhelming. Animal farming is a primary cause of deforestation (De Sy et al., 2015), biodiversity loss (Machovina et al., 2015), antibioresistance (O'Neill, 2015) and infectious diseases emergence and amplification (Rohr et al., 2019). Moreover, it contributes significantly to water pollution, water scarcity and climate change (Godfray et al., 2018; Poore & Nemecek, 2018; Springmann et al., 2017). Additionally, the exploitation of farmed animals, especially in its widespread intensive forms, raises various moral issues. In this paper, we discuss another impact of animal farming, that on air pollution and in turn on human health. While this impact is also potentially considerable, we stress that it has been largely overlooked by regulators as well as by researchers, and in particular by economists.

    Abstract: This study examines the effects of oil supply and global demand shocks on the volatility of commodity prices in the metal and agricultural commodity markets using the SVAR model. The empirical evidence is based on real time daily closing international commodity prices covering the period 2 December 2019 to 1 October 2020. The findings are presented in cumulative impulse responses and variance decompositions. The former is utilized to examine the accumulated influence of structural shocks on the volatility of agricultural and metal commodities whereas the latter reflect the share of variation in the volatility of each commodity arising from each structural shock. Various patterns are provided on how metal and agricultural commodity prices have been influenced by the COVID-19 pandemic. Policy implications are discussed.

    Abstract: This study contributes to the literature on the information and volatility transmissions for wheat. It investigates the relationship between the French spot market of wheat and its futures contract, through the information and volatility transfersthat occur between them. The analysis of the price discovery process, i.e. the information flow between both markets isbased on daily prices between 2001 and 2018, and applies a vector error correction model (VECM) for the cointegrated price series. The information share, the permanent-transitory and the component share price discovery metrics are then computed to analyzethe link between both markets. Our main finding is that the futures marketcompletely dominates the price discovery for wheat, making the French physical market and agricultural producers exposed to the effects that excessive speculation can have. Furthermore, the volatility spillovers between both markets are analyzed from 2010 to 2018 with a bivariate asymmetric quadratic GARCH model and a BEKK model. We find that volatility spillovers fromthe spot to futuresmarket are stronger thanfrom futuresto spotmarkets

    Abstract: India is one of the largest agrarian economy in the world, where, about 44 percent of the workforce are employed in agriculture contributing 14 percent of the GDP and about 10 percent of the country’s exports. However, the productivity of the labour force engage in agriculture has continuously decline. The conventional farming method has become unfeasible due to ever raising input prices. This has led to increase in rural indebtedness and serious agrarian crisis in India. The Zero Budget Natural Farming (ZBNF) help to eliminating rural indebtedness and degradation of natural resources in India. This paper presents some empirical evidence on ZBNF and its related myth and reality.

    Abstract: This study explores the entrepreneurial potential of the rule-breaking practices of microfinance programs’ beneficiaries. Using the storyboard methodology, we examine the strategies employed by the poor in Burundi to bypass institutional rules. Based on 66 short interviews conducted in seven rural provinces of Burundi, our exploratory study analyzes the entrepreneurial potential in four instances of rule-evasion: consumption spending, illegitimate investment, loan juggling and loan arrogation. We argue that some of the unruly practices are in fact entrepreneurial, as they create tangible and intangible value for the rural poor at both household and community levels. These include strengthening social ties through gift exchange and ceremonies, which then help poor households to self-insure against shocks through social networks. By analyzing the push and pull factors for unruly behavior, we show that rule-breaking practices are often necessitated by the microfinance industry itself and call for increased flexibility and adaptability of microfinance products.

    Abstract: Despite the substantial body of work focused on women farmers in India, the generational aspects of women farmers are often under-researched. Young women farmers (YWF) often get lost in discussions of youth in agriculture or women farmers more generally. In this paper, we present four case studies of young women farmers and discuss qualitative material from interviews with 22 women farmers from the Indian states of Tamil Nadu and Madhya Pradesh. Through detailed qualitative interviews, we map the trajectories of these women into farming and map the challenges they face in becoming and being farmers. The four case studies highlight several similarities and differences. While young women farmers in this study demonstrate that they take farming seriously, are knowledgeable and passionate about farming, they also face formidable constraints in accessing land and other resources, training, markets and so on and often lack agency and autonomy as farmers. Their experiences highlight the crucial role of family, social networks, community and state support in their efforts to become successful farmers.

    Abstract: In France, for nearly 150 years, the provision of water services fell under the responsibility of 36,000 municipalities which could organize these services at their own scale or within the framework of a variety of communal associations. Municipalities also decided if water services were to be publicly managed or delegated to private operators. Despite recurrent reforms, these arrangements remained in place for many decades, but in 2015 the NOTRe Law transferred jurisdiction over water services from 36,600 municipalities to 2,000 urban and rural communities. This Law is the culmination of a series of policy reforms aimed at restructuring the management of water services and constitutes a significant challenge for rural areas and small towns.

    Abstract: Like ESG investing, climate change is an important concern for asset managers and owners, and a new challenge for portfolio construction. Until now, investors have mainly measured carbon risk using fundamental approaches, such as with carbon intensity metrics. Nevertheless, it has not been proven that asset prices are directly impacted by these fundamental-based measures. In this paper, we focus on another approach, which consists in measuring the sensitivity of stock prices with respect to a carbon risk factor. In our opinion, carbon betas are market-based measures that are complementary to carbon intensities or fundamental-based measures when managing investment portfolios, because carbon betas may be viewed as an extension or forward-looking measure of the current carbon footprint. In particular, we show how this new metric can be used to build minimum variance strategies and how they impact their portfolio construction.

    Abstract: Even as a huge body of empirical evidence points to the cooperation-inducing character of shared water, popular narrative seems to get carried away in its visions of water wars and outright conflict. Theoretical literature largely focuses on bargaining and treaty negotiations as efficient solutions to intractable water conflicts. This paper attempts to explore the possibility of an efficient solution without explicit bargaining, even as players are locked in a contest over shared water. The paper locates water conflict within the scope of contest theory and obtains a cooperative outcome in a non-cooperative game using a linear Contest Success Function (CSF). This is true even when the conflict technology is not `sufficiently ineffective'. A range of outcomes over a spectrum of cooperation, partial conflict and outright conflict is obtained when production and contest abilities are expressed in generalised forms.

    Abstract: Food prices in Nigeria have become significantly higher and more volatile since 2012. The purpose of this research was to find out what affects farmers’ participation in the growth enhancement support scheme (GESS) in the country. We determined the effect of the GESS on the ease of access to market information and agricultural inputs that influence price volatility at farm gate level. A total of 2100 rural farmers were sampled across Nigeria’s six geopolitical zones. Result from the use of recursive bivariate probit model showed that farmers depended on the GESS for the resolution of food price volatility by providing food market information and agricultural inputs that bring down the incidence and amount of anxiety-impelled price rise in Nigeria. The results advocated for the need to improve the GESS in line with the agricultural transformation agenda (ATA) by cutting down the deterrents mostly linked with the use of mobile phones, and the distance of registration and assemblage centers. In extension and contribution, the findings suggest that smallholder farmers can be part of the volatility solution when they are provided with rural roads and transportation to get their product to the market, and technology to receive and share the latest market information on prices.

    Abstract: The authors assess to what extent the Enhanced Integrated Framework (EIF) provides assistance to LDCs through its "Diagnostic Trade Integration Study (DTIS)" towards more effective trade and development policies. The DTISs raison d'étre is to improve LDC's trade capabilities and - thence - reduce their levels of poverty. A key feature of LDCs economies are their agricultural commodities. DTIS are intended to guide LDCs in increasing the quantity, quality and value-addition of exports of agricultural commodities; creating jobs and increase welfare. Thus, better understanding how products best fit into the global supply and global value chains (GSC/GVC) becomes critical. Our analysis shows that the new guidelines for the DTISs of 2018 do not sufficiently address the Global/Regional Supply and Value Chains.

    Abstract: In India, as well as globally, agriculture faces an apparent generational problem, with youth reluctant to take up farming as an occupation. Yet there has been limited research in India using a generational lens to understand young people's trajectory in farming - their entry into and their continuation in farming. This study draws on in-depth qualitative interviews of a small sample of young men and women in farming communities in Madhya Pradesh. It focusses on young people's experiences in becoming and being farmers, privileging their own perspectives on the challenges they encounter in accessing land, knowledge and other resources and how they negotiate them. The study finds that contrary to popular perception and notwithstanding aspirations to move away from agriculture, several young farmers given a choice would rather engage in agriculture as a full-time activity and seek support to be able to do so. The study underscores the need to treat young farmers, both men and women, as a distinct analytical category from the perspective of policy making.

    Abstract: The use of organic official quality sign is growing for animal products production in France. Past researches have assessed the market performance of organic using attitudinal data. This paper investigates the impact of organic label on market performance using real market data. We use the hedonic price formation to understand the value of organic and the influence of store types in price formation. To complete the understanding of the organic official quality sign in the market, we calculate the price elasticity of organic among the other egg marks. Our results reveal a positive trend for higher quality products, and that core organic consumers are not price-sensitive, which increase market performance. This effect is mitigated by the store type which commercializes the organic product, highlighting the importance of the interaction between the two quality signals.
    Abstract: L'utilisation du signe officiel de qualité AB (agriculture biologique) est grandissante dans la production de produits animaux. Les recherches en marketing visant à mesurer les performances de marché du bio sont principalement basées sur des études déclaratives et hypothétiques. Fondées sur des données réelles de marché, l'objet de cette étude est d'analyser la performance de marché du label Bio. La méthode des prix hédoniques permet de définir la valeur de la caractéristique biologique du produit dans la formation des prix, ainsi que l'influence du type de distributeur. Pour compléter notre étude, une analyse de l'élasticité prix des produits bio par rapport aux autres marquages a été effectuée. Les résultats révèlent d'une part une hausse des ventes de produits de haute qualité, et d'autre part, un profil de consommateurs de produits Bio peu sensibles aux variations de prix. Ces deux tendances augmentent la performance du marché Bio. Cet effet est atténué par le type de distributeur qui commercialise le produit bio, mettant en lumière l'importance de l'interaction entre les deux signaux de qualité.

    Abstract: This paper studies whether fiscal policy plays a stabilizing role in the context of import food price shocks. More precisely, the paper assesses whether fiscal policy dampens the adverse effect of import food price shocks on household consumption. Based on a panel of 70 low and middle-income countries over the period 1980-2012, the paper finds that import price shocks negatively and significantly affect household consumption, but this effect appears to be mitigated by discretionary government consumption, notably through government subsidies and transfers. The results are particularly robust for African countries and countries with less flexible exchange rate regimes.

    Abstract: Anthropogenic climate change raises growing concerns about its potential catastrophic impacts on both ecosystems and human societies. Yet, several studies on damage induced on the economy by unmitigated global warming have proposed a much less worrying picture of the future, with only a few points of decrease in the world gross domestic product (GDP) per capita by the end of the century, even for a global warming above 4 ∘C. We consider two different empirically estimated functions linking GDP growth or GDP level to temperature at the country level and apply them to a global cooling of 4 ∘C in 2100, corresponding to a return to glacial conditions. We show that the alleged impact on global average GDP per capita runs from −1.8 %, if temperature impacts GDP level, to +36 %, if the impact is rather on GDP growth. These results are then compared to the hypothetical environmental conditions faced by humanity, taking the Last Glacial Maximum as a reference. The modeled impacts on the world GDP appear strongly underestimated given the magnitude of climate and ecological changes recorded for that period. After discussing the weaknesses of the aggregated statistical approach to estimate economic damage, we conclude that, if these functions cannot reasonably be trusted for such a large cooling, they should not be considered to provide relevant information on potential damage in the case of a warming of similar magnitude, as projected in the case of unabated greenhouse gas emissions.

    Abstract: What drives livelihood diversification among predominantly rural households in developing countries and how can welfare-enhancing patterns be established and sustained in the long run? A large literature has focused on whether income diversification is a means of survival or a means of accumulation, but it remains inconclusive. We first examine the pattern of income diversification for a panel of households in Tanzania from the 1990s?the Kagera Health and Development Survey?with a focus on whether it is primarily driven by survivalist or accumulation motives.

    Abstract: This paper presents an overview of the state of young women farmers in India as they navigate livelihoods in a sector that faces severe challenges. Discussions of young women farmers in India often get lost in those focused on women farmers more generally and of youth in agriculture, whereas they are a distinct analytical and empirical category who merit attention. Besides being discriminated against compared to male youth, young women farmers are further likely more disadvantaged than their older female counterparts (in addition to their male peers) in terms of access to productive resources and are relatively more constrained as economic actors, even though they tend to have more formal schooling and access to information. We argue that knowledge of their challenges and circumstance is vital for the visibility and recognition of young women farmers as well as for sound, inclusive policies to support them. This is especially relevant in a context where non-farm opportunities for young men outstrip those available for young women. Towards this end, we draw on existing data and review literature to map the participation and situation of young women in agriculture in India.
