Our extreme weather scenario results show that simultaneous weather-related shocks to crop yields in main exporting countries could lead to substantial increases in world food prices, threatening food security in countries strongly reliant on food imports. Maize and wheat prices increase by 40% and 50% due to extreme weather, increasing food expenditure in import-dependent countries (by up to 5%). Countering this effect, closing yield gaps in developing countries would substantially lower international prices and food expenditures, especially in developing countries. If the yield gap is reduced by 20% relative to economic potential over a 6-year period (yield gap scenario), maize and world prices decrease by 20% and 15%, decreasing food expenditure per capita in import-dependent countries. Finally, a combined scenario shows that the yield improvements only partially offset the impact of imported shocks on import-dependent countries, and these effects vary by country, depending on their production capability and their net-trade position. World maize and wheat prices increase by only 9% and 26% and still raise food expenditure in import-dependent countries.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 2","pages":"268-281"},"PeriodicalIF":3.4,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.12634","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183951","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}

By linking precipitation and temperature to rice yields and incorporating these relationships into a trade regime-switching partial equilibrium model, the research simulates future market conditions under alternative Shared Socioeconomic Pathways (SSPs). The analysis is divided into two parts: first, estimating yield variations for Bangladesh's two main rice harvests using historical weather data and stochastic simulations of future conditions; second, modelling the economic impacts of yield fluctuations under autarky and import parity regimes. The latter reduces the effects of domestic shocks but increases exposure to international market shocks. Climate variability interacts with trade regimes to determine food security outcomes: the effects on food availability and access, and the stability of food supplies, can be either nil or strong depending on the trade regime. The effectiveness of market interventions further depends on the trade regime in place, strengthening the case for more directly targeted support to food insecure households.</p>\u0000 </div>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 2","pages":"282-295"},"PeriodicalIF":3.4,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183953","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}

Through reduction of <i>D. plantaginea</i> fruit damage alone, our study shows that flower strips on the headland can be a positive financial investment. If non-crop land was not available, establishment of a flower strip in the centre of an orchard, instead of the edge, could recoup opportunity costs by providing benefits to crops on both sides of the flower strip.

We apply a game theory approach to analyse the strategic interaction between the Animal Health Authority (AHA) and the stockbreeders. The model elucidates how the breeders' pay-offs depend upon the AHA's choices and vice versa. We first model the stockbreeder reporting decision (passive surveillance) under uncertainty. Then, we analyse how the AHA should efficiently allocate resources between active surveillance (inspections) and intervention, and determine how this trade-off is influenced by various economic factors, such as the operation size and breeders' risk attitudes. By explicitly considering the relationship between passive and active surveillance, the model reconciles the literature investigating the nexus between compensation payments and reporting with the literature on the relationship between surveillance and intervention. We use the case study of a parasite of social bee colonies, the Small Hive Beetle, in Italy, which presents no moral hazard concerns, and hence limits the complexity of the analysis. However, the model can be adapted to other types of exotic diseases and livestock. The model does not provide precise quantitative prescriptions of the optimal values to be assigned to indemnities and probability of monitoring. Rather, it contributes to the understanding of the economic factors that influence optimal surveillance and intervention strategies.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 2","pages":"434-446"},"PeriodicalIF":3.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.12628","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143575366","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}

The objective is to ascertain the impact of such a transition on the competitive dynamics within the meat industry. The large meat processors in western France, which currently dominate the market, would only process a small fraction of the livestock that would be relocated, due to higher transport costs. Their reduced market volume and share would lead to reduced profits for these processors, with some potentially going out of business because of high fixed costs. Driven by economic opportunities, small and medium-sized processors would enter the market and locate in northern, eastern and southern France.
