This study examines the pathways through which coupled and decoupled subsidies influence farm-level production efficiency in China, focusing on farmland market rental distortions and farmers’ perceived tenure security. Using nationally representative household-level survey data and a multilevel chain mediation model, the results show that both types of subsidies are positively associated with farm-level production efficiency. However, only coupled subsidies exhibit significant indirect effects on farm-level production efficiency by reducing farmland market rental distortions and enhancing farmers’ perceived tenure security. In contrast, decoupled subsidies display limited transmission through these intermediate mechanisms. Further analysis reveals that the indirect effects of coupled subsidies are more pronounced in major grain-producing regions, where farmland market structures and subsidy targeting are better aligned. These findings suggest that farmland market conditions play a critical role in translating subsidies into productivity gains and that improving subsidy design to better reflect local farmland market rental distortions and tenure security can enhance their overall effectiveness.</p>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.70068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146096591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starting from near-autarkic policies that prohibited the import of edible oils, imports surged to meet most of the domestic demand following trade liberalization in the 1990s. While the domestic oils sector provides negligible employment, it uses domestically grown nontraded oilseeds, which occupy 14% of cultivated land and are next in importance only to the cereal grains of rice and wheat. These oilseeds are grown in the dryland arid regions where farm incomes are low and precarious. To examine spatial effects, the paper constructs geographically varying exposure to trade shocks that depend on the cultivated area planted with oilseeds. Consistent with a model of spatial price competition, the paper finds greater price impacts in the high oilseed growing regions. On the other hand, spatial impacts on wages are not significant, suggesting labor reallocation. While we do find significantly greater cropping pattern and production responses in the high oilseed growing regions; however, such evidence does not extend to labor reallocation outside agriculture.</p></div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146096384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building on a randomized experiment fielded in 2017, we explore the long-term adoption and impacts of a successful intervention with a genetically modified eggplant variety (Bt eggplant) in Bangladesh. We study the extent to which households exposed through this intervention to Bt eggplant continued to grow it after 5 years, and whether exposure to the improved variety had post-intervention impacts on a battery of eggplant-, agricultural-, economic-, and women's empowerment-specific outcomes. We find wide-scale dis-adoption of the Bt eggplant technology, driven primarily by difficulties in accessing seed as well as the absence of post-intervention support by extension specialists and implementors. Notably, we observe a change in seed-sourcing behavior in households exposed to Bt eggplant, with a shift towards the formal seed sector. We see no other effects on a variety of eggplant- and agriculture-related outcomes. We find no evidence that exposure to Bt eggplant at the household level had any positive or negative impact on dimensions of women's empowerment.

Utilizing a modeling framework that innovatively integrates the crop and livestock production systems in semi-subsistence economies, this study examines the interactions and dynamic adjustments within these systems following weather shocks, using Ethiopia as a case study. We also evaluate the effectiveness of various adaptation strategies in sustaining farm incomes, food security, and welfare. Results show unique effects on the crop and livestock sectors resulting from a joint shock on the two systems. While food crops experience a strong and immediate growth effect (12.4%) that fades quickly, the livestock sector faces the full impact of the shock a year later (13.7%), with the effect persisting to some degree. We also find diverging economic and livestock system adjustment trajectories from separate shocks to the crop and livestock systems. Further, the intervention options analyzed show contrasting impacts on various outcome indicators, with only the resilient crop intervention causing sector-indifferent impacts.

Assessment of the impacts of animal health and livestock diseases on the well-being of the live animal and value chain actors, as well as consumers, helps to quantify the efficiency of resource allocations in the livestock sector and to improve stakeholder decision-making. In this paper, we aim to illustrate how the impact of improved animal health affects the well-being of economic agents of the livestock sector of an economy. We specify a vertically integrated partial equilibrium livestock model to identify disease free equilibria as a special case of the Kuhn–Tucker conditions. We provide empirical evidence from a case study on the small ruminant meat value chain of Ethiopia. We find that the total surplus increase for a disease free small ruminant sector is USD 780 million under constant consumer demand. If meat demand increases according to the FAO projection, the surplus gain increases to USD 1.2 billion.

Transitioning from native savannas to introduced pastures significantly boosts productivity, particularly when paired with practices such as weed control and fertilization; however, yield gains fall short of the expectations set by agronomic trials.

These findings are grounded in social preference theory, and building upon it, we develop a social utility function that incorporates SVO and cooperative tendencies in the pursuit of modeling the trade-offs between self-consumption and contributions to public goods, linking social factors to farmers' decisions. Empirically, we use primary data collected through structured surveys and game-based experiments in northern Vietnam, then employ fractional and quantile regression (QR) models to explore the influences at different levels of adoption.
