Yet the quality of data collected in conflict zones is sometimes questioned and remains underexplored. This paper addresses this gap by examining two types of reporting bias—recall and question order bias—under varying levels of conflict in Myanmar. We focus on agricultural wages as the key variable of interest because wages are frequently measured in surveys and represent an important development indicator, serving as both a key input cost for farmers and a crucial income source for hired farm workers. We match ACLED conflict data with farm survey data collected across three panel rounds, with the third round including recall modules to assess recall bias. We also implement a question order experiment in the second round to assess whether the sequencing of wage questions by year and gender influences reported wages. We find modest recall bias in reported wages, but no statistically significant evidence that recall bias increases with conflict severity and only limited evidence of question order bias. Among the question order biases, only the interaction between conflict severity and asking about the previous year's wage first is statistically significant, and its magnitude is economically small. Overall reporting biases are modest and are driven more by the type of wage being reported than by conflict severity. We conclude that reliable data can be collected in conflict settings—and such data are rare but essential for evidence‐based policies and interventions as conflicts continue to rise globally.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"3 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148964295","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}

While the consequences of sanctions on political and macro-economic outcomes are well-analysed, rigorous evaluations of the causal impacts of sanctions on the agriculture and food (agri-food) trade remain limited. We obtain the causal estimates of sanctions' impact on agri-food trade by utilising samples that have been threatened with but not subject to sanctions to construct the counterfactual of the sanctioned sample. Exploiting an event study approach to analyse data from 154 countries over the period 1960–2016, we find that international sanctions mostly resulted in modest and short-lived declines in the total agri-food trade of sanctioned countries as opposed to the counterpart of countries under sanction threats. Trade volumes declined substantially for beef, pork, roots, dairy and fruit products. The decline in the exports of agri-food commodities resulting from international sanctions was more significant relative to the drop in imports. The study also reveals that the impact of sanctions on agri-food trade depends partially on the type of the sanction and on the sanction imposer. While the differences in the impact of sanctions across agri-food commodities largely reflect the fact that the commodities where there are stronger impacts are those produced more in countries subject to sanctions, future studies incorporating analytical tools from industrial organisation may provide more nuanced insights on why and how the trade of differential agri-food commodities was impacted by sanctions so differently.</p>\u0000 </div>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"77 3","pages":"1089-1101"},"PeriodicalIF":5.5,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148675342","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}

While the program has the potential to enhance sellers' reputations, evidence regarding its effectiveness is limited. This study estimates the association between FBA usage and seller reputation, measured by the average star rating a seller receives. Using fixed effects and staggered difference-in-differences estimation approaches as well as 26 weeks of panel data from Canada, the United Kingdom and the United States, three key findings emerge. First, using FBA is significantly and positively associated with a seller's reputation, leading to higher average ratings in the short term than in the long term. This improvement is mainly due to FBA's competitive advantages, such as eligibility for Amazon Prime, standardised fulfilment quality and excellent customer service. Second, although the correlation between FBA and reputation is positive in every country, we find cross-country heterogeneity in effect sizes and significance levels, with the largest effects in Canada. Third, we show that large sellers have the best reputation, and all sellers benefit from the FBA program. However, medium-sized sellers benefit the most from the program. This trend can be attributed to how the benefits of the FBA program accrue optimally to sellers based on their operational scale. These results suggest that the FBA program is indeed effective in enhancing seller reputation, with implications for third-party sellers, Amazon and regulators.</p>\u0000 </div>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"77 3","pages":"1122-1143"},"PeriodicalIF":5.5,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148842875","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 applied it with datasets for six sub-Saharan African countries, including hundreds of estimated parameters that transmit the effect of policy measures onto agricultural productivity. The approach demonstrates that reallocating agricultural public expenditure across policy measures in these countries can potentially boost agri-food output by several percentage points, create almost a million off-farm jobs in rural areas, lift almost 3 million people out of poverty and allow 16 million people more to afford a healthy diet—all without extra funding.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"77 3","pages":"910-927"},"PeriodicalIF":5.5,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.70053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288554","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}

Standard development theory suggests households manage shocks by substituting labor for capital. We show this mechanism fails in modern, mechanized agriculture because substituting labor for destroyed capital is infeasible in the short run. We estimate the impact of the February 2023 earthquakes in Turkiye on agricultural supply, separating extensive margin adjustments (cultivated land) from intensive margin effects (yields). This disaster represents a unique ‘dual shock’: physical capital destruction coincided with a liquidity crisis that blocked asset replacement. To analyse this, we adapt the Agricultural Household Model using a Leontief (fixed-proportions) representation as a short-run limiting case. Empirically, we employ a Synthetic Difference-in-Differences strategy, combining district-level crop statistics with remote sensing data. We find a significant contraction at the extensive margin: wheat cultivation declined by 8.5% relative to the pre-treatment mean in the 2024-restricted specification. Yet, we identify a ‘Null Yield Effect’ at the intensive margin. Yields remained stable or increased. This aligns with ‘Ricardian Selection,’ where producers—facing binding capital constraints—abandon marginal lands to concentrate resources on prime plots; consistent with this mechanism, the yield gain is concentrated in marginal, low-quality districts and absent where land is better. Sharp declines in new tractor registrations (24%) and agricultural credit (16.5%) confirm a ‘Scarcity Trap.’ In high-inflation, mechanized environments, cash transfers are insufficient. Policy must instead prioritize in-kind capital replacement to bypass liquidity constraints and restore capacity.</p>\u0000 </div>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"77 3","pages":"1102-1121"},"PeriodicalIF":5.5,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768799","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}

Although policymakers are increasingly considering market-based approaches such as taxes, their broader impacts remain insufficiently assessed. This study examines the environmental, economic and social impacts of a GHG tax on Swiss agriculture. Using the agent-based sector model SWISSland, representing 3077 farms and capturing heterogeneous responses to taxation and structural change, we simulate tax levels of 100, 200 and 300 CHF/tCO<sub>2</sub>eq for 2024–2030. We consider three mitigation pathways: technical measures, structural changes in land use and livestock numbers, and farm exits. We assess their impacts on GHG emissions, nitrogen surpluses, biodiversity, farm income, food production and food security. A GHG tax activates abatement mechanisms and induces dairy herd reductions, grassland extensification, shifts towards crop production for direct human consumption, and livestock farm exits. At 100 and 200 CHF/tCO<sub>2</sub>eq, emission reductions are mainly driven by technical measures, whereas at 300 CHF/tCO<sub>2</sub>eq they increasingly result from structural adjustment, including livestock farm exits and land reallocation to less emissions-intensive production. A tax of 100 CHF/tCO<sub>2</sub>eq reduces emissions by 5%, while higher tax rates achieve greater reductions but increase sectoral income losses from 13% to 25%. Food self-sufficiency and calorie production remain stable. The model also shows environmental co-benefits, including lower nitrogen surpluses and increased biodiversity areas.
