Using the Italian Farm Accountancy Data Network between 2018 and 2022, the study applies a difference-in-differences approach that allows assessment of the dynamic impact of insurance. The findings reveal that insurance participation has a persistent negative effect on farm income and productivity, particularly in the early years of participation. This decline suggests moral hazard behaviour, where insured farmers reduce entrepreneurial effort. However, no significant long-term changes were observed in fertiliser or crop protection usage, while usage increased immediately after insurance adoption but decreased in subsequent years.

We use a difference-in-differences estimator to analyse data from a 10-year panel of rural farm households from the Tegemeo Institute of Agricultural Policy and Development combined with conflict data from the Armed Conflict Location and Event Data, Commission of Inquiry into Post-Election Violence and Uppsala Conflict Data Program. We find that the post-election violence had a negative impact on household welfare. Specifically, exposure to post-election violence led to a 19% reduction in household per capita income. Notably, post-election violence had a negative impact on crop income and off-farm income but a positive impact on livestock income. Households may have resorted to selling their livestock as an ex ante or ex post coping strategy. Unlike crop production, some forms of livestock production such as dairy production involve daily rather than seasonal activities. Thus, it is plausible that similar forms of livestock production might have provided an economically viable ex post income generating strategy during PEV.

Drawing on a principal–agent framework, we use a controlled laboratory experiment to compare DMH, where processors can reduce agreed-upon prices ex post and farmers can side-sell, to single moral hazard (SMH), where only farmers can deviate. Contrary to the standard theoretical prediction of identical outcomes under full rationality, allowing processors to lower prices ex post leads to significantly lower initial price offers, greater side-selling and reduced contract acceptance; ultimately harming farmers' earnings. By contrast, SMH produces higher prices and a Pareto improvement in welfare. These findings highlight how buyer opportunism, exacerbated by weak legal systems and asymmetrical bargaining power, can erode smallholders' livelihoods in practice. We conclude that policies and contract designs aimed at limiting buyer discretion can mitigate double moral hazard and enhance the stability and equity of contract farming arrangements.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 3","pages":"640-650"},"PeriodicalIF":4.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.12646","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144929546","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}

Using household-level data on corn farmers in northern China from 2009 to 2017, this paper examines how farmers mitigate welfare losses caused by extreme temperatures by reallocating labour from farm to off-farm sectors, accounting for the heterogeneity across crop growth stages during which extreme heat occurs. We find that extreme temperatures increase the labour supply in migrant off-farm employment during the initial stage of the growing season, shift labour from corn cultivation to local off-farm employment during the mid-season and do not significantly impact labour allocation in the final stage. These labour shifts are primarily driven by production risks associated with yield losses and harvest failures, which reduce agricultural returns. Heterogeneity analysis reveals that farm households engaged in part-time farming and those with low dependency are more likely to use labour reallocation as an adaptation to extreme temperatures due to lower mobility frictions. Our back-of-the-envelope welfare calculations indicate that labour reallocation from agriculture to off-farm employment, induced by extreme heat, mitigates up to 60.29% of agricultural losses. Ignoring this labour reallocation may overestimate the effect of extreme temperatures on farmers' welfare losses.</p>\u0000 </div>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 3","pages":"582-601"},"PeriodicalIF":4.2,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568597","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 study estimates TFP using a stochastic production frontier model, then tests for convergence using a Panel Error Correction Model that allows for differences between countries and includes variables influenced by policy: cumulative R&D investment (as a proxy for knowledge), trade in capital goods (to capture knowledge spillovers), and education spending (as a proxy for human capital). The study finds no evidence of absolute convergence, that is countries are not all heading toward the same productivity level. However, conditional convergence toward different steady states is observed for all countries except Guatemala. Although most countries are moving toward separate productivity levels, investment in R&D, trade openness, and improved education can both close productivity gaps and raise overall long-run productivity.

In this paper, we evaluate the effect of agricultural policies in the form of farm subsidies on halting the loss of grasslands due to woody plant encroachment. To this end, we assemble a novel panel dataset that connects the farm-level census data of Swiss alpine summer farms and high-resolution remotely sensed woody plant encroachment data. To deal with the endogenous selection of claiming subsidies, we leverage an agricultural policy reform that abruptly and unevenly increased subsidies, allowing us to estimate the causal effect of subsidies at the farm level on woody plant encroachment. Our results show that an increase in subsidies causes a loss of 2% of grassland due to woody plant encroachment, which corresponds to an average loss of 4.7 ha of grassland per farm.
