We find that the timely submission of reports to the authority increased by at least 5.7 percentage points, from a baseline of 70.3 per cent. This result suggests that highlighting the consequences of noncompliance—such as imprisonment and fines—through a loss aversion message effectively encourages compliance. These effects sustained for over a year in some regions, though being marginally significant. The loss aversion message has the greatest impact among both the smallest and largest companies.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"230 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546379","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 conduct a structural estimation to analyse the potential bargaining power of different types of actors in the farmland market. It allows us to infer their latent reservation utilities by exploiting equilibrium conditions, derived from a stochastic ultimatum game. Reservation utilities reflect outside options in negotiations, as they are determinants of bargaining power. We conduct economic experiments in the rental market. Our findings show that farmers and local actors have more bargaining power than non-farmers and absentee actors, respectively.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"79 1 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071929","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 survey and incentivized experimental data, we find that market experience is significantly associated with increased adoption of improved agricultural technologies. Furthermore, we find that market experience is linked to reduced risk aversion and a stronger internal locus of control, which, in turn, are associated with higher technology adoption. Our findings imply that policies aimed at increasing farmers’ investment in improved agricultural technologies benefit not only from providing access to these technologies but also from addressing psychological barriers.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"145 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841573","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 setting provides a unique social structure, shaping people’s responses to leadership. We find that leading-by-example set by political leaders and randomly selected leaders increases participants’ contribution by 1.432 and 1.162 Chinese Yuan, which is an increase of approximately 22 and 18 per cent of average contributions in the control group. The difference in the effects of leading-by-example set by political leaders and randomly selected leaders is small and statistically insignificant. Contributions under the leading-by-example treatments are driven by increased contributions from leaders and mimicking behaviour of followers, although following political leaders is weaker. Our findings highlight the crucial role of leading-by-example and strong village-level institutions in the provision of public goods.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"6 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902262","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 highly disaggregated trade data, this paper investigates the presence of regional agglomeration effects in Norwegian seafood exports. Results indicate strong agglomeration effects in the exports of both farmed and harvested seafood at the region–product–destination level. Regional agglomeration of exporters affects the firms through different margins. In both industries, increased agglomeration results in larger volumes, while aquaculture exporters experience a small, negative, price effect. The largest firms, both in the number of employees and size of product portfolio, export most. We also document that agglomeration is important in explaining the creation of new regional product-destination-specific trade relationships, indicating the presence of regional spillover effects.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"13 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678350","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}
