Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports. We consider the degree to which wheat markets in twelve British cities were spatially integrated over the nineteenth century by applying conventional threshold models and semi‐nonparametric (generalized additive) models of spatial price linkages. Although results concerning market integration are qualitatively similar, the semi‐nonparametric models capture important nonlinearities that may be missed by conventional threshold models. Both approaches support a high degree of integration among the spatially distinct markets. We then consider two sub‐samples from 1800–1840 and 1870–1913 to capture price transmission before and after the repeal of the Corn Laws, the development of the railway system, the improvement of steam engines for ocean transport, and the introduction of the telegraph system. The nonlinear models suggest faster equilibration in response to large shocks and tighter transaction cost bands in the second period.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"26 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743781","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 paper quantifies the effects of 2025 US tariff hikes and potential tit‐for‐tat retaliation on agri‐food trade, prices, output, and welfare. We employ a sectoral general‐equilibrium gravity model covering 46 agri‐food industries on a 2023 baseline. The framework combines product‐level trade elasticities with sector‐specific supply elasticities based on input‐cost shares, providing a transparent mapping from tariffs to equilibrium outcomes. We simulate the April 2, 2025 (‘Liberation Day’) tariff schedule and the July 31, 2025 revisions, each with and without symmetric retaliation by all trading partners. Without retaliation, US agri‐food exports fall by 22%–25%, output declines by about 3%, the price index rises by 6.8%–7.2%, and welfare falls by 4.4%–4.9%. With retaliation, export losses deepen to 37%–43%, output drops by 4%–5%, the price index rises by 2%–5%, and welfare declines by 6.9%–7.9%. Welfare losses are highly asymmetric: Canada and Mexico experience the largest additional losses under retaliation, reflecting integrated North American supply chains, while contractions are concentrated in processed meats, soybeans, corn, and selected food products. Retaliation amplifies global welfare losses rather than offsetting them, suggesting that cooperative policy restraint yields smaller welfare costs for the United States and its major trading partners.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"5 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743778","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}

However, the two approaches are rarely combined. In this study, we test the performance of result‐based payments with collective contracts in a contextualised economic experiment with 540 non‐agricultural and agricultural students in Germany. Combining result‐based payments with collective contracts may hold potential by allowing farmers to share the risks associated with result‐based payments within a group. A downside of collective contracts, however, is the creation of a social dilemma, as individual payments depend on group outcomes. We find no evidence of differences in conservation levels under result‐based payments with collective as compared to individual contracts, suggesting that risk‐sharing benefits and effects of the social dilemma offset each other. We further examine the performance of collective contracts for varying risk levels that could, for example, reflect different geological and climatic conditions across Europe. Result‐based payments with collective contracts motivate higher conservation efforts in our experiment when external risks are high. Further, high risks appear to foster group cooperation under collective contracts, potentially leading to more equitable and predictable outcomes.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"36 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743833","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}

In this article, we discuss how health prioritization and environmental concerns, combined with new technologies, are changing consumers' food preferences and retail choices. Wellness trends have increased attention to functional attributes and specific nutrients such as protein, while intensifying scrutiny of ultra‐processed foods. Adoption of personalized technologies, including prescription medications, wearable devices and diet‐tracking apps, may alter the volume and composition of food consumed. Many consumers are also willing to pay a premium for sustainability claims, but may conflate environmental standards and healthfulness, which raises questions about credibility and effective labeling design. All of these considerations may be impacted by affordability concerns following a period of supply‐chain disruptions and disease outbreaks since 2020, causing food price inflation. This, combined with increasing income inequality, has resulted in a bifurcation of demand between value and premium consumer segments. Preferences are further separated by the channel consumers use to purchase food, as many households still purchase groceries online and order meals for delivery after the COVID‐19 pandemic. The availability of highly detailed consumer purchasing and health data allows for compelling future research on the causal relationships that arise from these trends, which will continue to shape the global food environment.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"33 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695751","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 examines whether small seed packs distributed either for free or at a subsidised price enhance farmers' knowledge and subsequent adoption of improved legumes, drought‐tolerant maize, and improved traditional African vegetables in Tanzania and Zambia. Drawing on mobile phone survey data and applying entropy balancing alongside machine‐learning methods to address selection bias, we find consistent evidence that seed packs increase both technical knowledge and adoption of these crops. Knowledge gains are strongest for crops with limited prior exposure, while improvements for familiar crops such as drought‐tolerant maize likely reflect experiential learning rather than new information. Adoption effects are positive across all crops and robust to alternative estimation strategies. Overall, the results indicate that small seed packs can serve as an effective demand‐creation tool, particularly in settings where farmers face information gaps or uncertainty about the performance of improved germplasm.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"14 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695753","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}

To foster an environmentally sustainable food system, it is vital to change consumers' food choice patterns to be more environmentally sustainable. This study presents a concept ladder , a simplified model under which consumers may be at different stages in terms of their willingness and ability to make environmentally sustainable food choices: some may have little concern, others may have more concern but require the impetus of broader social norms to modify their choices, while a final group may have strong concern but in some cases be unable to exercise their preferences because of financial or other constraints. To empirically test this concept, we conducted a large‐scale randomised experiment involving Japanese consumers through two online surveys. In the first survey, respondents were randomly separated into three groups and provided with either environmental issue information (T1), social norm information (T2) or no information (Control). Two weeks later, a follow‐up survey was conducted to compare the actual environmental sustainability of food choice behaviours among the groups. The results show that the treatment effect of T1 is the largest for those with a low level of environmental concern, while the treatment effect of T2 is the largest for those with a moderate level of environmental concern, consistent with the ladder concept. Several robustness checks support these findings.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"22 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586729","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}

Despite the availability of effective mitigation technologies, their adoption often remains limited due to behavioural and institutional constraints. Water management practice that extends drainage periods during cultivation can curb methane emissions from irrigated rice at low cost, yet uptake among Japanese farmers remains modest. We surveyed 2219 rice producers in Shiga Prefecture using a labelled choice experiment that embedded two behavioural nudges (social norm and loss aversion) and one informational boost (knowledge enhancement), presented with or without a reminder. Farmers most favoured a 7‐day drainage extension. Social‐norm messages did not robustly shift adoption intentions, but loss‐aversion and knowledge enhancement paired with reminders increased the probability of choosing water management practice by 5–10 percentage points, particularly when financial incentives were modest. The added value of nudges and boosts faded once subsidies approached prevailing ceiling levels, suggesting diminishing marginal returns to stacking instruments. These findings suggest that timely, low‐cost behavioural interventions can effectively complement agri‐environmental payments in resource‐constrained settings, providing a scalable and context‐sensitive strategy to accelerate the adoption of climate‐smart rice practices.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"3 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586730","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}

Using a district‐level panel dataset from 2000 to 2020, this study examines the impacts of salinity on Winter–Spring rice yields and acreage and how farmers adapt to salinity risk. A Nerlovian adaptive expectations model is applied to assess how past exposure influences land‐use decisions. Results show that extreme salinity events exert a stronger and more persistent effect on acreage adjustments than year‐to‐year fluctuations, with reductions most pronounced in salinity‐prone and coastal districts. Spatial heterogeneity underscores the need for location‐specific strategies: infrastructure and salt‐tolerant varieties for inland areas, and support for transitions to alternative land uses in highly exposed regions. Evidence of complementarities between rice and aquaculture suggests integrated systems can sustain production under moderate salinity pressure. These findings highlight the importance of tailored interventions to enhance resilience as salinity intrusion intensifies with sea‐level rise.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"297 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147536458","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}

The insurance hypothesis suggests that extensively managed, species‐rich grassland is more drought resistant than intensively managed grassland. However, it produces lower yields in non‐drought years, creating a trade‐off between maximising yield and improving stability. In this study, we analyse how this trade‐off translates into farmers' management decisions. Using a mechanistic bio‐economic model, we evaluate outcomes across a wide range of simulated ecological, climatic and economic input conditions. We apply classification tree analysis to identify key drivers of extensive management under expected utility, cumulative prospect theory and an extension we call reference‐based valuation, where outcomes are valued relative to management‐specific expectations. Results suggest that farmers who evaluate profits against the expected outcome under each management intensity potentially adopt extensive management despite lower expected profit if it offers greater stability during droughts. By contrast, when outcomes are compared to the status quo of intensive management, or when farmers maximise utility, extensive management is only predicted if foregone yields do not outweigh higher drought stability. Our findings highlight that adoption decisions depend strongly on the valuation perspective, motivating further applications of reference‐based behavioural models and research on how farmers' reference profits might evolve under climate change. They also suggest policy entry points: targeted extension services and demonstration farms could broaden evaluation perspectives, while financial incentives such as payments for ecosystem services could reduce adoption thresholds due to forgone yields under profit‐oriented decision‐making.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"16 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507836","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}
