{"title":"Dynamically optimal cover crop adoption","authors":"Le Chen, Roderick M Rejesus, Zachary S Brown, Christopher N Boyer, James A Larson","doi":"10.1093/erae/jbaf018","DOIUrl":"https://doi.org/10.1093/erae/jbaf018","url":null,"abstract":"This paper develops a stochastic dynamic programming model to investigate optimal cover crop adoption policies, accounting for cumulative effects on soil fertility, uncertain future fertilizer and output prices, irreversibility of sunk machinery costs and flexibility in the timing of adoption over time. Based on data from a 35-year cotton field experiment in West Tennessee (1984–2018), we first estimate the static and dynamic yield effects of cover crop adoption and then use these estimates to evaluate the decision of a representative cotton farmer to adopt three cover cropping practices—hairy vetch, winter wheat and crimson clover—under conventional till and no-till production systems. Econometric estimates imply significant cumulative effects of cover crops on yields, as well as static and dynamic substitution effects between cover crops and nitrogen fertilizer inputs. With these substitution effects implying increasing marginal profit from soil fertility, our analysis suggests a threshold level of soil fertility level, above which it is optimal to adopt cover crops and below which it is not. Adoption of cover crops is more favored if no-till practices have been implemented. Moreover, in the presence of sunk costs that have not yet been incurred, the optimal strategy is to postpone the adoption of cover crops in both conventional till and no-till fields until crop prices improve, the cost of adoption decreases, or fertilizer prices increase. Our results also indicate that when fertilizer prices are higher, cover crop adoption in no-till systems can lead to substantial fertilizer cost savings, with the amount of those fertilizer cost savings increasing over time as soil health further improves.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"20 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144202048","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}

Our analytical model conceptualizes the competition between an incumbent industry and a competitive fringe, each producing differentiated products. Although motivated by the β-carotene case, the model is versatile and applicable to other contexts involving novel products entering markets dominated by established technologies. Developed by university researchers and commercialized by start-ups, natural β-carotene was eventually integrated into major synthetic corporations. Initially niche and costly, it gained market competitiveness through innovation and expanded applications, driving technological advancements and significantly benefiting the broader algae-based industry.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"57 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144113912","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}

While previous studies have focused on farm productivity and income variability, this study examines the relationship between crop diversification and farm performance, considering farm size, socio-economic status and location. Using French Farm Accountancy Data Network data from 2010 to 2022, we analyse 19,822 observations from 3,246 crop-focused farms. Results show that small farms benefit from crop diversification, while large farms face income challenges from diversification. Additionally, crop diversification increases the efficiency of larger farms.

Most circular-bioeconomy supply chains, however, are still in their infancy. We propose a conceptual model that characterizes the farm decision to adopt the circular use of agricultural residues such as animal waste and corn stover. The model highlights the complementarity between farm outputs and the residue and pins down key determinants of adoption. We illustrate how the economic forces work by examining two budding circular-bioeconomy supply chains—biochar and black soldier fly.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"10 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893139","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 study uses daily price volatility data from June 2015 to December 2023 and a time-varying parameter vector autoregressive framework to investigate short-term and long-term connectedness dynamics. The results show a strong relationship between crude oil and agricultural commodity prices in India. Soybean oil is a significant transmitter within the network, and crude oil emerges as a primary net recipient. The average total connectedness index (TCI) value was about 36 per cent, with 27 per cent in the short term and 8.9 per cent in the long term. The average TCI value during the Coronavirus disease (COVID-19) period was 32.6 per cent, and that during the Russia–Ukraine war period was 24.3 per cent, with volatility spillovers in the network occurring primarily in the short term. Dynamic variations in connectedness over time highlight the impact of specific events, such as the COVID-19 pandemic and the Russia–Ukraine war. This study identifies the net transmitters and net receivers of volatility shocks within a network, providing insights that can help with portfolio diversification and strategic decision-making.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"183 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822825","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 a discrete choice experiment (DCE) with 1987 respondents from the UK, we find evidence against this assumption. Affirmative disclosure, which indicates only quality above the lowest level, lowers marginal utilities compared to complete disclosure. The development in food choice DCE studies, from textual and complete towards visual and affirmative increases mean willingness to pay and error variance. This suggests that analysts should carefully consider how attributes are presented when designing DCEs to avoid biased welfare estimates, especially when aiming for accurate market predictions or policy advice.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"183 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736502","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 a dynamic setting, retailers can potentially sustain an equilibrium of higher profits by collectively withholding non-cage-free eggs.
