Despite progress, social vulnerability considerations have been largely overlooked in existing policy and academic discussions. Through narrative analysis of interviews with experts and actors from the Spanish honey value chain and European institutions, we explore nested layers of food fraud vulnerability: product and supply chain-related food fraud vulnerabilities, social vulnerabilities, institutional vulnerabilities, and vulnerabilities related to international trade and market dynamics. Particular emphasis is placed on understanding how these dynamics affect vulnerable actors and limit their ability to respond to fraud. In a sector dominated by small and medium-sized beekeepers, food fraud poses a major threat to the viability of beekeeping. Key vulnerabilities include regulatory gaps, inconsistent detection methods, and global trade pressures that disproportionately affect vulnerable value chain actors. In particular, we highlight social vulnerability factors like low participation in decision-making, and unequal distribution of fraud-related risks and responsibilities throughout the value chain, which undermine trust between actors. Beekeepers and their associations advocate for geographical indication (GI) schemes, direct trade, and short supply chains to reduce fraud risks, address power imbalances, and improve traceability and authenticity. This research highlights the need for regulatory frameworks that promote equity, transparency, and fair risk sharing. It contributes to embedding social vulnerability into food fraud vulnerability concepts and advocates for socially responsible governance that prioritizes the rights and resilience of all actors within the agri-food system.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"136 ","pages":"Article 102954"},"PeriodicalIF":6.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096158","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}

However, consumer acceptability is a precondition for implementing behavioural change interventions, and there is a current knowledge gap regarding public acceptability of various retail-led interventions. In this study, we assess consumer acceptability of five categories of food retail-led interventions: <em>information-based</em>, <em>norms-based</em>, <em>choice architecture</em>, <em>price-based</em>, and <em>choice restriction</em>. In this mission we developed a survey and recruited a nationally representative sample (n = 424), we found price manipulations and choice restrictions to be less accepted than strategies building on information, norms, and choice architecture. Furthermore, a multi-level model showed that perceived effectiveness, fairness, and freedom of choice were significant predictors of acceptance for the interventions, with the exception that freedom of choice did not predict support for either the norm-based intervention or choice architecture. Lastly, we showcase how older age, positive meat attitudes, and strong meat-buying habits hindered acceptance, while biospheric values, environmental identity, and altruism facilitated it. Two potential courses of retailer action are identified: (1) immediately implement high-support interventions based on information, social norms, and choice architecture and (2) explore how to convey intervention effectiveness to increase consumer acceptability of price-based interventions and choice restrictions.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"136 ","pages":"Article 102971"},"PeriodicalIF":6.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145262780","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}

While these two inputs are ‘paired’ together for integrated soil nutrient management, empirical studies often focus on the use of one of these inputs as a dichotomous choice. This study models the joint use of hybrid seeds and inorganic fertilizer and its impact on different dimensions of food security. The analysis is based on a sample of 1,653 unique maize growing households (3,306 observations) over 4 rounds of the Living Standards Measurements Study – Integrated Surveys of Agriculture (LSMS-ISA) from Tanzania, spanning 10 years between 2010/11 to 2020/21. The Multinomial Endogenous Switching Regression with Correlated Random Effects (MESR + CRE) models self-selection into four potential regimes of input use. The results show that the Average Treatment on the Treated (ATT) of joint inputs use increased maize productivity by 17–39 % and improved food utilization with more diverse diets, by 1.9 food groups in some cases. Further, Average Treatment on the Untreated (ATU) estimates show that farms that do not use both inputs could improve their food security. However, the improvements are restricted by low profitability or even losses under joint input use. Sub-sample analysis in this study shows that the treatment effects are quite heterogenous. Households with more exposure to heat and moisture stress and limited access to services face lower profitability on adoption, limiting the impact on food security outcomes. The findings from this study suggest more targeted approaches to incentivize joint input use and diversification of strategies since agricultural input-based interventions may have limited impacts for households exposed to adverse weather and experiencing severe food insecurity.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"136 ","pages":"Article 102948"},"PeriodicalIF":6.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997063","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}

We employ a staggered difference-in-differences approach to estimate the impacts of benefit reductions resulting from EA expiration on SNAP participation rates, investigating the roles of changing initial application and recertification rates in explaining these impacts, suggesting underlying changes in the returns to participation and household decision-making. We also employ interaction models to examine how impacts differed with income, extending these models to further investigate the role of income in EA expiration’s impacts on food insufficiency. Results indicate that early EA expiration reduced the SNAP participation rate by 1.48 percentage points on average. This reduction grew over time following expiration and was driven by a reduction in the number of initial applications to SNAP. Further, we estimate that reductions in SNAP participation were concentrated among relatively higher-income households who would have experienced larger reductions in benefit levels.

Social networks can potentially be a key tool to disseminate information about such technologies, because informal discussions among network members could counter the lack of observability and awareness of the benefits of such technologies. To inform this issue, we conducted a field experiment that included experimental auctions and a lottery to estimate how social networks influence the demand for Aflasafe, a new food safety-enhancing technology, among smallholder farmers in Senegal. Aflasafe is an agricultural input that controls aflatoxins, which are unobservable carcinogenic compounds that contaminate grains and compromise their safety for human consumption. Despite the lack of any food-safety regulations or price incentives in the study area, we found that demand for Aflasafe was high at baseline after farmers were trained on its benefits. The results show that social networks increased demand for Aflasafe among participants who had a lower willingness to pay in the first period. These individuals likely needed the most convincing to adopt the technology. Further, we find suggestive evidence that having an Aflasafe adopter (“lottery winner”) who used the treated groundnut for own consumption and use as future seed in an individual’s network increases their demand. Having an adopter who used the treated groundnut for other purposes in an individual’s network is not associated with any change in an individual’s demand. These findings suggest that smallholder farmers – who are often both producers and consumers of their food – engage in discussions about technologies with unobservable benefits within their agricultural social networks. Thus, it seems possible, at least in the short term, that these networks can be harnessed to increase technology adoption by leveraging farmers’ concern about their health and food safety.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102934"},"PeriodicalIF":6.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144780096","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}

Its objective is to assess the support, perceived intrusiveness, and perceived effectiveness of specific interventions designed to (dis)incentivize the consumption of (un)healthy foods. Additionally, it aims to identify the factors influencing the support of such measures among this vulnerable segment.

Findings reveal that food labeling and educational campaigns are more widely accepted and perceived as more effective than other nudges, whereas taxation is perceived as the most intrusive policy. Subsequent econometric analyses highlight the crucial role of perceived effectiveness and intrusiveness in determining policy support. Furthermore, personal and behavioral characteristics significantly influence approval, as citizens tend to oppose interventions that seek to restrict established habits. Adapting policies to reflect these variations could enhance their relevance and effectiveness, ultimately improving their impact on public health.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102928"},"PeriodicalIF":6.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144750311","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}
