Findings of multivariate analyses do not provide convincing evidence that the health-risk information enhances the acceptability of meat taxes and meat-free days.

Explorative heterogeneity analyses provide some suggestive evidence that providing health-risk information increases the acceptability of the policies for certain subgroups, but only in specific countries.

An existing literature documents the effects of school meals and school meal nutrition standards on child outcomes, yet causal evidence on how this program affects nutritional intake is still lacking. We compare nutritional intake between the periods just before and just after the school year begins for children likely to be eligible for free school meals (incomes under 200% of the poverty guideline) versus students unlikely to be eligible for or participate in the program (incomes above 200% of the poverty guideline), using granular data we collected about school year start dates. Using a difference-in-differences approach, we find access to school meals reduces caloric intake, driven by a reduction in soda consumption for younger children, and a reduction in total fat intake for older children. Given increasing obesity among school children and the specific ways that calories are reduced, these findings likely represent improvements in students’ diets. We do not find any statistically significant effects on food insecurity or any spillover effects onto mothers’ consumption or time spent on food activities, which suggests these effects come from changes in children’s access to school meals and not from other differences between the academic year and summer for school meal eligible vs. higher income families. These results suggest school meals programs can improve nutritional intake, and policymakers should consider this benefit when considering changes to availability such as expanding or reforming universal free meals programs.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"134 ","pages":"Article 102901"},"PeriodicalIF":6.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297412","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}

This study adopts a global supply chain perspective and primarily utilizes the Import Side of Foreign Production Exposure (FPEM) indicator to assess the risk exposure of China’s bioeconomy, based on data from the OECD ICIO tables. The findings indicate that the overall levels of domestic and foreign risk exposure across various sectors of China’s bioeconomy are relatively high, which makes it more vulnerable to supply chain disruptions than the U.S. and the EU. However, the proportion of foreign risk exposure in China’s bioeconomic sectors remains relatively modest, ranging from approximately 7% to 12%. Moreover, the look through foreign risk exposure of China’s bioeconomy consistently exceeds its face value foreign risk exposure, suggesting that certain foreign supply chain risks may be concealed. Notably, the Agriculture sector shows the most significant increase in look through foreign risk exposure, implying a gradual rise in potential risks. While the hidden foreign risk exposure in the Food sector demonstrates relatively low volatility, its underlying external dependencies remain a critical concern that should not be underestimated. Additionally, our research shows that the U.S. and China are each other’s largest actual foreign suppliers of intermediate inputs in the bioeconomy. This study not only provides critical insights for the risk management of China’s bioeconomic supply chains but also offers valuable lessons and implications for the security and sustainable development of global bioeconomic supply chains.

While most approaches focus on increasing productivity using improved inputs like fertilizers, an alternative, relatively understudied method involves multiple-season farming—cultivation across multiple periods in a year, enabled by conditions such as irrigation or alternative water access. Using panel data from the World Bank Living Standards Measurement Study (2010–2019) in Malawi, we examine how multiple-season farming shapes household food security, child nutrition, and resilience, defined as persistent food security over time. To mitigate selection bias, we employ fixed-effects and instrumental variable fixed-effects models. We find that multiple-season farming is statistically significantly associated with improved household food security (at the 1% level), particularly for asset-rich and male-headed households. Multiple season farmers cultivate more diverse crops and engage in market sales, which enhances their food supply. However, we find no significant impact on child nutrition. Using Cissé and Barrett’s (2018) moment-based method to estimate resilience, we provide suggestive evidence that multiple-season farming also positively affects household resilience. These results point to the potential of multiple-season farming to bolster food security and help farmers adapt to climate change. Our results also highlight the need for interventions that support poor and female-headed households to access the inputs needed for multiple season farming.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"134 ","pages":"Article 102833"},"PeriodicalIF":6.8,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144231056","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}

Belgian participants (N = 1151) shopped for groceries in a purpose-built Virtual Online Supermarket with a prescribed shopping list.

Compared to the control group, the mere presence of Nutri-Scores did not affect the outcomes of interest. Changing the default sorting from alphabetically to by healthiness improved the mean diet score, increased the purchase of items with Nutri-Scores A and B, and reduced the purchase of items with Nutri-Scores D and E. In contrast, when present, the user-driven options to filter and sort the products by healthiness were barely used (<10 %), and this intervention didn’t change purchases.
