Although recent health care mandates have improved access to healthcare, many agricultural employers still do not offer coverage for their employees. Because farmworkers tend to be seasonal, and sometimes migratory, worker health is often considered a common property resource. If farmers cannot retain the benefits due to offering worker healthcare coverage, the market for firm-provided coverage fails and workers are not covered. We estimate the economic value of offering health coverage to farmworkers and their employers using a structural search, match, and bargaining model. We find that farmworkers with employer-provided health coverage are significantly more productive than those without and, on average, generate an additional <math>\u0000 <mrow>\u0000 <mtext>$</mtext>\u0000 <mn>0.85</mn>\u0000 </mrow></math> in economic surplus for each hour worked.

The economic and social costs of large-scale spread of disease when there is no cure for the disease, only preventative measures implemented in coordination and cooperation with others, will be effective at addressing the problem. To better understand these challenges in an agricultural context, we create an agent-based model (ABM) coupling ecological, epidemiological, and economic factors to simulate Huanglongbing (HLB) spread in California. The ABM is used to evaluate how participation in collective action through coordinated area-wide insecticide spraying is influenced by perception of other growers' participation and confidence in scientific information about the disease. We find a grower's participation in coordinated spraying has little influence on when the infection reaches them but depends primarily on the other growers' action. We discover that over time more growers cooperate in area-wide coordinated spraying, but after the disease has sufficiently spread, some growers stop cooperating. Moreover, as beliefs in other growers' participation becomes stronger, some growers cooperate less, leading to greater HLB spread. We observe that increased confidence in scientific information lowers HLB spread, as more growers are motivated to cooperate through increased expected cumulative profits. As such, a successful strategy to combat an incurable infectious disease, like HLB, and collective action problems, in general, requires careful consideration of growers' perceptions of their neighbors' behavior and trust in scientific information.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 5","pages":"1457-1476"},"PeriodicalIF":3.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12535","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habits may also affect consumer responses to exogenous shocks, including changes in policies targeted at consumers. Adequately defining and measuring habits is therefore important for both understanding and predicting consumer behavior. In this paper, we develop a habit index that is based on regularity of observed purchases. Our index is suitable for comparing habitualness across product groups and types of households. We estimate the index using Danish home-scan food purchase data and find that across product groups, habitualness is higher for breakfast foods and products with short shelf lives. Across households, habitualness decreases with household income and is higher for households whose main shopper is male. We also examine how habitualness affects price sensitivity and responsiveness to Danish fat and sugar taxes. We find that habitual consumers are less sensitive to general price fluctuations, but more responsive to tax changes.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"1059-1086"},"PeriodicalIF":4.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12534","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence of their impact on agricultural production and the adaptation strategies employed by farmers remains limited. This paper estimates the impacts of sandstorms on crop yields and examines the associated adaptation strategies. Using data from 288 counties in China's winter wheat production regions spanning 2000 to 2007, we uncover a substantial 14.8% reduction in winter wheat yields in northern China due to sandstorms. Each additional hour of sandstorm during the winter wheat growing season corresponds to a 1.4% decrease in yield. Household-level data further reveal that sandstorms not only threaten food security by reducing crop yields, but also lead to a significant decrease in planted areas. Furthermore, we find that farmers increase their investments in fertilizer and labor as adaptation measures to mitigate the negative impacts of sandstorms on crop yields. Our results suggest that timely irrigation following a sandstorm, especially in areas with less precipitation, can effectively mitigate its adverse effects, offering valuable insights for reducing the economic impact of sandstorm events. These findings underscore the need for adaptive strategies to safeguard agricultural productivity in the face of increasing sandstorm risks, offering valuable insights for policymakers and stakeholders engaged in agricultural resilience planning.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"1087-1116"},"PeriodicalIF":4.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525122","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 BLP model accounts for variations in the trade impacts of OEAs by considering unobserved, product-specific, agro-ecological comparative advantages and bilateral trade costs. The BLP estimation offers a more realistic trade pattern, showing that exporters producing and selling close substitutes for organic agrifood products with the competitors in the market would be more sensitive to the establishment of OEAs between the competitors and the market. Results indicate that OEA partners of the importer would achieve a higher share in this market than non-OEA partners. The simulation results suggest that Peru would have captured 23.8% of the 2019 U.S. market share if Peru had signed an OEA with the U.S. in 2017. Additionally, Mexico and Turkey would have secured 35.1% and 1.8% of the 2019 Canadian and Danish markets, respectively, had the Mexico–Canada and Turkey–Denmark OEAs been in effect since 2017. These findings, along with changes in the market shares of other exporters under a hypothetically established OEA, provide new insights into organic trade patterns and highlight the potential for further development of OEAs.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 4","pages":"1183-1227"},"PeriodicalIF":4.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144525123","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}

Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set-aside's trade-offs in England between 1992 and 2007. Mixed biodiversity outcomes are reflected in a marginal effect, of a 100 ha increase in set-aside, associated with a 1%–2% increase in species abundance and richness, no impact on Shannon-Wiener diversity, and a 0.03 standard deviation fall in phylogenetic diversity. Lower phylogenetic diversity indicates that populations of less genetically distinct bird species appear when set-aside increases. These effects are discontinuous for abundance and richness, and larger in the long run than in the short run for richness and phylogenetic diversity. Set-aside led, on average, to a 7%–9% fall in cereal land. In turn, this led to an up to 2% decline in cereal output. A yield increase of 5%–10% is likely due to the setting aside of mostly marginal land. Biodiversity–food trade-offs in agricultural landscapes could be minimized with a carefully targeted set-aside policy, based on clearly defined biodiversity goals, and in settings where there is still scope for intensification.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"254-284"},"PeriodicalIF":3.3,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12530","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While they can reduce local yields, widespread production losses often drive price increases. This study presents a panel approach that accounts for the price–yield correlation to assess the impact of such events on crop revenues, focusing on U.S. corn and soybeans. It conducts two key analyses: (1) quantifying the revenue impacts of the historic 1988 and 2012 U.S. heatwaves and (2) examining the implications of climate change on crop revenue variability. The results show that compensatory price increases often substantially offset yield losses, especially when price responsiveness to supply shocks is strong. In particular, U.S. corn in 2012 and soybeans in 1988 saw crop revenues rise by more than 8% compared to normal weather conditions, whereas U.S. corn in 1988 and soybeans in 2012 experienced decreases of no more than 4%. The study highlights the importance of crop-specific and time-varying price responsiveness to supply shocks. Furthermore, it demonstrates that if growing season weather during 1997–2019 had exhibited the volatility projected for 2036–2065 under a moderate emissions scenario, revenue variability for corn and soybeans in median U.S. counties would have increased by more than 60%, with more pronounced impacts in regions outside the major Corn Belt. These findings underscore the significant economic risks posed by climate change–induced variability in agricultural revenues.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"176-203"},"PeriodicalIF":3.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12527","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding differences in productivity among farms and its persistence over time helps assess the vulnerability of agricultural production to these external shocks. In this paper, we study productivity dispersion for European agriculture, assess the importance of different productivity components such as technical efficiency and environmental components, and investigate the persistence of productivity and its components over time. We measure total factor productivity based on a stochastic production frontier model applied to accountancy data from more than 100,000 farms and 26 European countries over the period 2004–2018 (N = 740,256). The results reveal a substantial dispersion in total factor productivity, even within the individual countries and farm types. Environmental factors play important roles in explaining these differences. Productivity persistence is high overall, but varies across farm types; for example, it is lowest for granivore farms and higher for mixed farms. We find that productivity persistence is slightly increasing over time, pointing toward improvements in the resilience of European farming systems during the considered period.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"204-231"},"PeriodicalIF":3.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12529","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One approach to extension is based on experiential learning and involves participation in an incentivized framed experiment (or game). The other is based on conventional “narrative-based” learning. While both modalities increase farmer knowledge, incentivized gamification causes more learning. We also find that experiential learning affects follow-up demand for the insurance product, which is not true for narrative-based learning. Interestingly, demand for insurance shifts inward after playing the insurance game. This reduction in demand is mainly caused by increased knowledge about the insurance product, but we also present suggestive evidence that experiencing basis risk during the game was more salient than theory-based learning about basis risk. Game-based learning is an effective approach to promote knowledge accumulation and may accentuate or attenuate adoption of innovations by updating ex-ante, possibly biased, expectations.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"232-253"},"PeriodicalIF":3.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12528","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
