An empirical application to Dutch dairy farms illustrates the distortions in the inefficiency scores and in the estimates of their determinants that occur when the dependence between good and bad outputs is ignored. The empirical results indicate a strong positive dependence between the good output (milk) and the bad output (methane emissions), which is particularly pronounced in the upper tail of the distribution. Notably, farms exhibit high efficiency in maximising their good output and minimising their bad output. Subsidies are negatively related to good output inefficiency but positively related to bad output inefficiency, while stock density exhibits a negative association with inefficiencies in both outputs. Disregarding output dependence leads to distortions in inefficiency estimates, particularly affecting the estimates for their determinants.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"11 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142610208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Area‐yield crop insurance, which links payouts to average yield in a geographic zone, attempts to increase demand by more accurately targeting insurance payouts to production shortfalls. However, shifting from an exogenous weather‐based to an endogenous yield‐based index introduces concerns of asymmetric information, which can lead to market failures that constrain supply from providers. These features are inversely related: larger insurance zones inhibit index manipulation, but average yield is less informative about any individual plot. We quantify this tradeoff for maize in Ghana using a spatial yield model calibrated to match observed production. Insurers must demarcate zones of no more than 5000 farmers for area‐yield insurance to outperform weather insurance. The framework presented in this paper allows assessment of the relationship between index performance and asymmetric information in new crop insurance products.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"132 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142536598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine whether exposure to exogenous climate shocks moderates these relationships. We construct individual‐level nutrition measures and time‐varying climate extremes using nationally representative panel data. To address endogeneity concerns, we use an instrument variable approach. Results show that commercialisation leads to an improvement in the broad nutritional profile of individuals. However, the commercialisation–nutrition linkage is weaker for households exposed to frequent climate shocks than those in climate‐resilient areas. Importantly, climate shocks dampen the positive nutritional impacts of commercialisation and exacerbate existing inequalities in the nutritional status within the households. Women and girls appear disproportionately vulnerable to the nutrition‐weakening effects of weather stresses in commercialised agricultural households. This highlights twin policy challenges: strengthening smallholders' resilience to escalating climate risks alongside promoting gender‐equitable, nutrition‐sensitive agricultural commercialisation.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"96 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Government of India has implemented several measures to enhance crop yield, including recommending and promoting the adoption of crop‐specific agronomic practices. However, there is limited empirical evidence on the determinants of the adoption of these practices and their impact on yield and income. In this context, this study analyses the determinants of the adoption of climate and plant management practices among black gram and green gram farmers and their impact on yield, crop revenue and net income across four major crop‐producing Indian states using a multinomial endogenous treatment effects model. Our analysis shows that information, contact with government extension services and access to off‐farm activities are crucial in adopting climate and plant management practices. The results strengthen the view that the adoption of knowledge‐intensive practices happens via formal information sources and plot‐level demonstrations. In addition, the results indicate that farmers who experience frequent crop loss exhibit an aversion towards adopting climate and plant management practices. While adopting these practices had a positive impact on crop yield and crop revenue, the impact on net income was observed only in the case of climate management.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"44 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on the impact that livestock farming can have on the quality of a water body and investigates farmers' willingness to cooperate to preserve water quality under two different sources of uncertainty and four different degrees of uncertainty. The first source relates to the level of water quality that must be guaranteed in a river catchment to avoid irreversible deterioration of aquatic ecosystems (threshold uncertainty, i.e. with catastrophic consequences). The second source relates to the financial losses that farmers will experience in the long run if they fail to cooperate (impact uncertainty). To this end, a lab‐in‐the‐field experiment was conducted with livestock farmers of Northern Ireland. A local public good game with threshold uncertainty was framed around an agri‐environmental scheme designed to create ungrazed buffer zones for water quality preservation. Results indicate that uncertainty generally hampers farmers' cooperation and the provision of information geared to reduce uncertainty enhances it. Impact uncertainty has a milder negative impact on cooperation than threshold uncertainty. Risk preferences and probability weighting do not influence cooperation, while loss aversion has an influence on cooperation.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"22 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the underlying mechanisms remain underexplored. A better understanding of these mechanisms could unpack the subsequent effects of conflict‐induced food and welfare shortages, as well as identify promising policy interventions. We study the effects of terrorist violence on household agricultural production in Burkina Faso and explore the underlying mechanisms. To achieve this, we combine nationally representative five‐year panel data on plots and households with spatial conflict data. Our analysis reveals negative and significant effects of terrorist violence on agricultural productivity and total output. Despite reducing cereal crop output, increased intensity of terrorist violence is significantly associated with higher production of cash crops, which require fewer inputs in Burkina Faso. Further investigations uncover that the decline in household agricultural productivity results from a significant decrease in the number of farming plots, land size, and short‐term production investments, including chemical fertilisers and pesticides. These findings remain robust across various alternative empirical specifications and measures of violence, offering insights that can help policymakers faced with similarly scaled armed conflict. For instance, ensuring a secure environment and providing reliable access to essential production inputs, such as chemical fertilisers and pesticides, can help support conflict‐affected household agricultural production during and after the violence periods.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"1 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141895692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using daily weather and firm-level data for the 2004–2019 period, we show that a heat wave causes, on average, a reduction in Total Factor Productivity (TFP) of about 3.2%. Smaller firms are more severely affected, with a reduction of approximately 7%, revealing unequal impacts within the same country and sector. The reduction in TFP can be partially attributed to lower workers' productivity, with labour input increased in order to compensate for productivity loss. The estimated effect is heterogeneous across subsectors, with some well-known Italian products (e.g., wine production) more severely affected by heat waves. These findings have significant policy implications due to the expected increase in the frequency of heat waves caused by climate change, and are particularly important in the case of the Italian food industry, which is mainly composed of small firms.
