One of the key obstacles is the risk of dissatisfaction among rural voters and the potential loss of electoral support. In this paper, we demonstrate that such political costs may arise not only from policy reforms that are actually implemented, but also from reform proposals that are put forward but never enacted. We illustrate this with an example from Poland, where, in 2020, the government attempted to reform animal welfare regulations. The proposed law was highly unpopular among farmers, sparked numerous protests, and was ultimately not passed. We provide evidence that, despite the withdrawal of the reform, the governing party suffered a significant decline in support among the rural electorate in the first elections following the attempt, and that this decline was more pronounced in municipalities where livestock production was relatively more important. The interpretation that the party's poorer performance in rural areas may have been due to the animal welfare proposals is further supported by several robustness tests.</p>\u0000 </div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146256482","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}

We measure the degree of systemic risk—and evaluate the effectiveness of risk pooling—in a hypothetical portfolio of insurance policies for U.S. corn and soybeans. We model dependence using vine copulas that capture potential asymmetries, tail dependence, and nonlinear associations. Our results indicate a reduction in overall risk when policies are pooled across space, decreased capital per policy held by the insurer to prevent ruin, and weakened tail dependence at moderate distances.

Leveraging these farmers' queries and crop yield–related datasets at the district level, we assess the impacts of weather and paddy pest infestation information on seasonal paddy yields. Endogeneity concerns are addressed using an instrumental variable (IV) approach—previous years' paddy yields and percentage gross irrigated area as IVs for pest and weather-related queries, respectively.

Despite this importance, their socioeconomic implications remain insufficiently understood. This paper examines the relationship between agrifood value chain participation and income inequality. Using panel data from 137 countries over the period 1990–2020, we find a negative association between global agrifood value chain participation and income inequality, largely driven by the food and beverage sector. Delving into the underlying mechanisms, we show that this inequality-reducing effect operates through labor reallocation away from informal, low-productivity agricultural activities towards more formal and better-paid downstream processing jobs, and a process of structural upgrading toward industry and services in countries that deepen their participation in the food and beverage sector. We also highlight significant disparities across regions and income groups. These findings carry significant policy implications and underscore the need for policymakers in developing countries to strengthen agrifood value chains through further transformation, with the aim of increasing incomes, generating employment, and reducing income inequality.</p>\u0000 </div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146176099","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}

Drawing on county-level agricultural data (1985–2019) and climate data (1965–2019), this study employs a panel fixed effects model to assess the impacts of climate change on the area shares of wheat, maize, and rice in Northern China, as well as their implications for grain production. The results reveal heterogeneous crop-specific responses. The growing degree days (GDDs) is positively associated with maize area—with each 10°C·day increase in GDD associated with an approximately 0.24% rise in maize area share—while having a significantly negative effect on wheat. These effects are more pronounced in colder regions and in a single-cropping system, reflecting agroecological heterogeneity. On the other hand, increased precipitation is associated with expansions in both wheat and maize area shares, with the effect being more evident for wheat. These climate-driven adjustments in Northern China contributed to an estimated 1.42% increase in China's total grain output over the study period. Further mechanism analysis, using competing crops as a case, shows that the positive impact of GDD on spring maize productivity is notably greater than that for spring wheat, suggesting that higher GDD enhances the comparative advantage of maize, thereby expanding its area share while reducing that of spring wheat. We also find that increased precipitation is significantly associated with multiple cropping index (MCI) increases, offering an additional adjustment pathway. By incorporating socio-economic factors into the analytical framework, our results indicate that improved irrigation capacity can effectively moderate the impacts of climate change on cropping patterns—by mitigating the negative effect of GDD on area shares of wheat and rice, and strengthening the positive effect of GDD on maize. Additionally, the adverse impact of GDD on wheat is substantially weaker in major grain-producing counties compared with nonmajor ones. These findings enhance our understanding of how staple crop structure in Northern China responds to climate change and the attendant implications for food security. Our analysis can help policymakers to formulate more targeted adaptation strategies that optimize land use and sustain stable grain production.</p>\u0000 </div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146162323","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}

We find that economic reform led to substantial, long-term increases in the production for at least four of these crops. However, the underlying drivers of these impacts appear to be crop-specific. For tea, increases were concentrated on the intensive margin, with yields nearly 87% above counterfactual levels, while land area rose only modestly.

Using data from two rounds of a nationally representative cross-sectional survey conducted before and after the ban and employing a propensity score matching difference-in-differences framework, we find that alcohol prohibition led to significant increases in caloric, protein, and fat intake from healthy food sources. The policy was also associated with a decline in fat intake from unhealthy food sources. These findings are robust across a range of specifications and estimation strategies. Heterogeneity analysis reveals stronger effects among urban households, wealthier cohorts, and marginalized castes.

This paper examines the impact of the SNWDP's central route on agricultural and ecological outcomes, with a particular focus on grain yield measured by the normalized difference vegetation index (NDVI). NDVI is used because it provides high-frequency, fine-resolution measures of vegetation health on both cropland and non-cropland, allowing us to capture impacts on agricultural productivity as well as broader environmental conditions. Using a combination of difference-in-differences, instrumental variable estimation, and event study analysis, we find that the project significantly increases NDVI and grain yield. Further analysis shows that the project improves vegetation health more broadly by increasing the Leaf Area Index, surface water area, and soil moisture content, thereby confirming an enhanced water supply for irrigation and ecosystem support.
