This systematic data review examines whether default nudges in food choices have consistent effects across different socio-demographic groups, or whether their impact varies depending on factors such as education level, age, and gender. After selecting eligible studies, authors from 12 studies shared their primary data and were subsequently included in the Default Nudge Research & Data Sharing Consortium (Table A2). These primary data enabled us to analyze 40 interaction effects examining whether age, gender, and education moderate the effectiveness of defaults relative to active choice conditions. Results show no consistent and rarely any interaction effects, suggesting defaults influence food decisions similarly across socio-demographic groups. A possible exception is that harmful defaults may be more effective among less educated individuals. These findings highlight default nudges as a broadly equitable behavioral tool in food policy design.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"141 ","pages":"Article 103114"},"PeriodicalIF":6.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I conduct an artefactual field experiment with Ghanaian cocoa farmers. Experimental subjects had an option to invest in a package of fertilizer bundled with index insurance. The returns depended both on the subjects’ investment choices and on a stochastic weather realization. The key ingredient of the study was whether the exact probability of bad weather was known or not. This probability was ambiguous in the experimental treatments, and the degree of this ambiguity varied across treatments. A large negative effect on fertilizer investments was found in treatments with either small or large ambiguity. The effect of large ambiguity was also found to be significantly stronger, suggesting that technologies with which farmers are relatively more experienced are more likely to be adopted under index insurance schemes. I provide new evidence that ambiguity may be a significant factor limiting the effectiveness of index insurance in promoting agricultural innovation. The overall findings are complementary to related recent randomized controlled trials, since it is effectively impossible to precisely calibrate and vary the level of ambiguity using the latter methodology.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"141 ","pages":"Article 102854"},"PeriodicalIF":6.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a Principal Component Analysis of 91 Danish, German, Polish, and Spanish value chain stakeholders’ sorting of 28 barrier statements, we extract five shared viewpoints, pointing out the perceived most important barriers: (1) a lack of capacity for end-product production and use; (2) unattractive legume products; (3) governance, institutional and capacity gaps; (4) unfavorable food system conditions; and (5) a restricted domestic raw material production. Cross–country analyses reveal that some viewpoints are widely shared, whereas others are country–specific. Our findings underscore the need for a flexible portfolio of European and national policy measures, such as educational initiatives, institutional support, network development, and coordinated national and regional strategies, to effectively address the value chain barriers currently inhibiting the realization of the full potential of food legumes as a pathway toward a more sustainable European food system.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"139 ","pages":"Article 103033"},"PeriodicalIF":6.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145975347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated that the implementation of funeral reform significantly enhanced the multifunctionality of cultivated land, particularly by improving its production function and living function. These effects were more pronounced in transportation hubs and major grain-producing regions across North, Northeast, East, and Central China. Mechanism analysis demonstrated that these improvements were primarily driven by the expansion of land transfers and the reduction of land fragmentation, which facilitated the development of large-scale agricultural operations. However, a trade-off was identified, where funeral reform significantly increased local air pollution, with average CO concentrations rising by 0.0949 mg/m<sup>3</sup> and SO<sub>2</sub> concentrations increasing by 3.2490 µg/m<sup>3</sup>, respectively.

We use a large dataset covering 71% of the EU market to analyze the relationship between dairy farmers’ decision to produce organically and their profitability. Moreover, we investigate the decision of these farmers to exit organic production. Our results reveal that organic farms achieve, on average, a higher profitability. However, the probability of exiting the organic market increases consistently in the years after conversion, peaking in year eight, which reflects difficulties in the transition process. Subsequently, exit probabilities decrease as farms seem to have familiarized themselves with organic production methods and positioned themselves in the sector. Finally, downward fluctuations in profitability and price premiums for organic milk are associated with a higher exit probability. The results show that policy-makers should specifically target the early phase after conversion and provide risk management instruments to support policy targets for organic production.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"139 ","pages":"Article 103034"},"PeriodicalIF":6.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146024707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
