This study employs an agent‐based model to investigate the influence of a significant agroecological transition in France, which would entail a reduction in production and relocation of livestock to regions outside western France. 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. In all scenarios, increased production by small labour‐intensive firms does not offset the impact of reduced production on job losses.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"56 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598816","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 model the CBIO and fuel markets using a structural model to simulate the impacts of RenovaBio. We link this model to a widely used model of agricultural and agricultural markets to analyse crop and crop product interactions. If implemented as announced, the programme would expand biofuel consumption and feedstock prices while decreasing petroleum product use. Our estimates highlight the potential for large impacts, similar by some measures to the impacts of US biofuel use mandates, subject to uncertainty about how the reduction targets evolve and how the industry responds. A programme of this type in a major biofuel and agricultural commodity producer and user affects global agricultural and food systems, as Brazil's supply to the world market diminishes and prices of ethanol and biofuel feedstocks worldwide are increased, depending on how the programme is implemented.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"8 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598811","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 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.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"13 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assesses the potential of cropland reallocation to simultaneously increase production and decrease nitrogen balances, and its impact on crop diversity. Our technological specification extends the by‐production approach by dynamically modelling the impact of the N balance from the previous year on current year crop production. We use a robust order‐m data envelopment analysis to estimate the production frontier, and the Hill‐Shannon index to assess crop diversity before and after optimal cropland reallocation. The application uses Farm Business Survey data from farms in England and Wales between 2015 and 2019. The results show that efficiency gains would have increased crop production by GBP 10.31 per ha and decreased the nitrogen balance by 1.05 kg per ha, when compared with a business‐as‐usual scenario. Reallocation, only focusing on increasing production, would have increased crop production by GBP 83.74 per hectare and reduced the nitrogen balance by 2.01 kg per ha. Reallocation, focusing on increasing production and decreasing the nitrogen balance, would have increased the former by GBP 71.88 per hectare and reduced the latter by 4.99 kg per ha. The median cropland diversity increases by approximately 0.24 species per farm in both reallocation scenarios. Our results suggest that farmers can simultaneously improve economic and environmental performance, which would increase crop diversity. Effective policies should address barriers to diversification and foster management practices that both increase production and decrease nitrogen balances.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"22 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462825","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}

Aligning such standards between countries should reduce or eliminate the additional market access costs and enhance trade. Yet, whereas evidence abounds on the trade effects of country‐specific public mandatory food standards, relatively little is known about the trade effects of regulatory homogeneity across countries. Exploiting the EU–Swiss trade relationship and data on maximum residue limits (MRLs) for pesticides, we assess the channels that explain the effects of regulatory homogeneity of standards on agri‐food imports. Estimating a reduced‐form gravity model, we find that similarity in Swiss‐EU MRLs on a product‐pesticide pair increases Swiss product‐level imports from the EU by 10%. This consists of a 7.7% increase in the average import value per product per firm, a 1.4% increase in the number of product varieties imported and a 0.6% increase in the number of importing firms. Regulatory homogeneity also increases import volumes by 9.4% and decreases import prices by 1.6%. Accounting for firm heterogeneity, we find more pronounced trade effects for smaller firms. These findings are confirmed in firm‐product level estimations, where we also find that the import‐enhancing effects increase with increasing regulatory heterogeneity. Our results imply that even with mutual recognition, there remains a preference for imports that align with domestic standards. In terms of policy implications, our findings show that regulatory homogeneity enhances food security by increasing product variety and lowering prices.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"58 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393450","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}

An important issue in the transformation process of agricultural production is the role of small farms. While many authors have looked at this question, one aspect that has received little attention is the role of small farms in the production of nutritious foods, an important topic given the low availability and relatively high prices of nutritious foods and the consequent low level of nutrition security in the continent. Using a unique large‐scale dataset from Ethiopia—one of the largest countries in Africa that has been transforming rapidly—we look at the production of vegetables and dairy products. We find a strong association between farm size and partial productivity measured in terms of output, value of outputs and profit per hectare/cow, with productivity twice to four times as high for larger farms. These farms have substantially higher input expenditures as well as differences in farm technologies compared to small ones. Our findings have important implications for the debate on the role of small farms and nutritional improvements in the continent.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"145 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030739","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}

Responding to this need, the Danish parliament recently decided to impose a tax on greenhouse gas (GHG) emissions from the country's livestock production. We develop a simple model of primary agriculture and its interaction with the food industry to illustrate the main economic mechanisms determining the impact of a unilateral tax on GHG emissions from domestic agriculture. To study the allocation effects of the GHG tax on agriculture and the impact on the wider economy over time, we then present a disaggregated dynamic simulation model of Danish agriculture, embedded in a large-scale computable general equilibrium model. The model predicts that a large share of the cost increase induced by the tax will be shifted forward onto higher input prices in the food industry and ultimately onto consumers via higher food prices, but landowners will also bear a significant part of the burden through a fall in land prices. The GHG tax will induce a reallocation from animal to plant production, which would be even more pronounced in the case of a livestock-specific tax as currently foreseen, and from conventional to organic farming. This will help to reduce the total emissions from agriculture, but the largest share of the emission cuts will stem from a fall in output, as there are still few low-cost technical abatement possibilities in agriculture.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"76 1","pages":"3-23"},"PeriodicalIF":3.4,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.12624","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142968275","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}

We adopt a conceptual framework based on real option value theory, which underpins an empirical analysis of a detailed dataset comprising 326 applications submitted under both the 1997 EU novel food regulation and its 2018 replacement. We investigate the dynamics of novel food applications under these regulations and disentangle the determinants of successful cases. Our results show a relatively stable number of applications over the years, with a spike after the introduction of the 2018 regulation, which sought to simplify and centralise the approval process. This upsurge can be interpreted as a reduction in the real option value of postponing investments, attributable to the introduction of a transitional regime and of 5-year data protection measures. However, the new regulation did not shorten the authorisation process, with the expected benefits of centralisation compromised by operational bottlenecks and a lower chance of approval. Finally, we find that approvals under the 2018 regulation are more likely when applicants are private entities from non-EU countries and have substantial experience with novel foods. Our empirical evidence suggests that the new regulation may be insufficient to speed up and streamline the novel food assessment process, which is inevitably constrained by EU food safety principles.
