The production environment in the region is subject to numerous constraints imposed by climate, physical infrastructure, and human activities. This study highlights the importance of countries’ natural endowment and crop-specific requirements, namely soil and climate characteristics, on agricultural trade and food security. To analyze the global supply of crops, we based our research on the comparative advantage theory with the factor endowment approach. We found that the climate in the tropical region lowered the soil quality and the agricultural productivity in the region. Compared to most developing Asian countries, least developed countries from Africa, including Madagascar, struggle with soil management which lowers their comparative advantage in the agricultural sector. We also found that the crops’ requirements give a comparative advantage to well-endowed countries. This research exposed that the climate and soil combined, along with the geography variables are important for the international trade pattern. It also brings light to the importance of international trade in the achievement of global food security. Our findings suggested that foreign direct investment (FDI) can be used to boost the global agricultural sector and improve global food security. For Madagascar in particular, we found that FDI could help the country sustain the global supply of spices, specifically vanilla, cloves, and cocoa.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"115 ","pages":"Article 102403"},"PeriodicalIF":6.5,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1767315","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}

Our model incorporates a system of Laspeyres price and quantity indices that link structurally estimated community-level produce supply functions to market level demand functions. The supply estimation accounts for corner solutions associated with disaggregate land use observations and is constrained to reproduce aggregate supply data. We use the model to assess climate change impacts in Israel, which protects local agriculture by import tariffs and quotas. The simulation results vary greatly when we allow prices to change as a response to supply changes, highlighting the importance of endogenizing prices in climate change simulations. The results imply that climate changes projected for Israel are expected to be beneficial to farmers, particularly due to the positive impact of the forecasted large temperature rise on field crop production. Fruit outputs are projected to decline, and reduce consumer surplus, but to a lower extent than the increase in total agricultural profits. Nearly 20% of the profit rise is attributed to farmers’ adaptation through land reallocation. Adaptation to the projected reduction in precipitation by increasing irrigation is found to be warranted from the farmers’ perspective; however, it is not beneficial to society as a whole. Abolishing import tariffs effectively transfers surpluses from producers to consumers, but the impact of this policy on social welfare is relatively modest.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"115 ","pages":"Article 102311"},"PeriodicalIF":6.5,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1767316","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}

Chinese governments have issued and supervised the implementation of relevant administrative regulations, which have not achieved good results. Peers are the most important social factors influencing children and adolescents' behavior and decision-making besides family members. This study examines how the peer effect impacts SSB consumption. To clarify this relationship, we use the nutritional cognition of peers' parents as an instrumental variable to resolve the endogeneity problem and employ the two-stage least squares estimation method to investigate the data of 4,118 students in north China. The results show a significant positive correlation between sugar intake among peers, indicating that individuals are more likely to consume excessive amounts of sugar when their peers also engage in this behavior. We find that the peer effect is enhanced with increased popularity among one's peers and gradually decreases as the distance within the social network increases. It is also more significant in short-term friendships than in long-term friendships. Our findings provide a basis for school-level intervention programs from the perspective of social interaction to regulate healthy eating behaviors and nutritional perceptions among children and adolescents through peer relationships. It also confirms the feasibility of reducing individual sugar intake by increasing nutritional awareness among adolescents and parents.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"115 ","pages":"Article 102413"},"PeriodicalIF":6.5,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1704565","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 conducted a nationwide survey in the U.S. that embeds a school lunch discrete choice experiment. Results indicate that students and parents would prefer that locally produced items be added to school lunch menus. However, while parent and student preferences align on some aspects of locally sourced meal elements, their preferences are not identical, with parents displaying a higher willingness to pay for locally sourced vegetables and students displaying a higher willingness to pay for locally sourced fruit. Joint choices are influenced by both parties. Parents dominate the joint outcomes when the household income is lower, when students eat school lunch more frequently and in dyads featuring a female parent and female student compared to male parent-male student dyads.

{"title":"How responsive are nutrients in India? Some recent evidence","authors":"Jaya Jumrani","doi":"10.1016/j.foodpol.2022.102379","DOIUrl":"https://doi.org/10.1016/j.foodpol.2022.102379","url":null,"abstract":"<div><p>The relationship between nutrient intake and income is an issue of huge policy relevance, especially in the developing world. Using large-scale household-level data from India, this paper analyzes how macronutrient and micronutrient intakes respond to changes in income in both rural and urban areas. It also investigates how food consumption patterns change over time. In a first, this paper employs different estimation approaches i.e., parametric, semi-parametric and non-parametric estimation models to obtain more recent and robust nutrient-income elasticity estimates for three macronutrients and four essential micronutrients. The parametric (OLS) calorie-expenditure elasticities were lower than those estimated for protein and fat. Micronutrients also yielded positive and statistically significant elasticities. In terms of the parametric (IV) estimation, elasticities also declined over time and had lower magnitudes than the parametric (OLS) estimates. Relative to protein, fat and micronutrient intakes, caloric intakes are less sensitive to changes in income. According to parametric (OLS and IV) estimation, calcium is the most income-responsive micronutrient, while zinc is the least. The preferred semi-parametric estimation strategy provides full flexibility to income effects while also simultaneously controlling for additional covariates parametrically, assisting in determining the true relationship between nutrient intake and income. Consistent with the parametric estimation, elasticities were positive and statistically significant. The augmented semi-parametric elasticities, which address endogeneity concerns, were lower than the non-augmented ones. The semi-parametric elasticity curves depict that the relationship between demand for nutrients and income is indeed non-linear and non-monotonic. The findings from this research demonstrate that it is critical to evaluate the effect of income across the entire income distribution, and not just at the means. Even when the elasticities are low, they are always more pronounced for the poor, who are the most vulnerable to malnutrition. The study conducts a battery of checks that further lend credence to the robustness of the main findings. Given the current landscape of India’s nutrition economy, the findings of this study would serve to be useful for designing apt future nutritional interventions and public health policies.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"114 ","pages":"Article 102379"},"PeriodicalIF":6.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1704569","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}
