While an increasing number of studies have investigated the health consequences of school feeding programs, empirical evidence regarding their effects on children's health inequality remains limited. This study examines the impact of China's Nutrition Improvement Program (NIP)—A program that provides free meals for rural students at the compulsory education stage—on rural children's health status and urban–rural health status differentials. The analysis uses data from the 2004–2015 China Health and Nutrition Survey. Leveraging county‐by‐county rollouts of the program, we employ difference‐in‐differences approaches as our identification strategy. The results show that the NIP significantly improves children's height‐for‐age z‐scores by 0.136 standard deviations. Moreover, we find that the NIP alleviates the inequality of opportunity in health between urban and rural children by 21.6% in pilot counties. These findings are robust to a series of validity checks. The effect is more pronounced among students who have a younger age, and live in low social status families. Our findings suggest that school feeding programs are effective in decreasing child malnutrition levels and reducing urban‐rural inequality in the long run.

Since the dairy industry is a significant contributor to carbon emissions, the recently launched “Double-Carbon” goals in China may also suppress the supply of dairy products, further reducing Chinese residents' dairy intake. While the notion of sustainable (i.e., nutritious and environmentally friendly) food consumption has recently gained popularity in the policy arena, whether Chinese milk consumers are ready to embrace this notion and what specific measures can effectively promote sustainable milk consumption in China remain unclear. On the basis of a discrete choice experiment, this paper examines how information nudges (i.e., randomly provided messages with different contents and details) may steer Chinese consumers into choosing liquid milk products with attributes that are more nutritious and environmentally friendly. Our analysis, involving 839 consumers randomly selected from Beijing, China, shows that consumers value carbon labels the most, followed by nutrition claims, sustainable production claims, and energy conservation certificates. Meanwhile, nutrition information induces consumers to place higher values on nutrition claims; in contrast, environmental information raises consumers' willingness to choose environmental sustainability-related attributes. Finally, the concreteness of the information provided strengthens these effects [EconLit Citations: D12, Q01, Q13, Q18].","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":"39 S1","pages":"1512-1534"},"PeriodicalIF":3.2,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136213149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a randomized single-blind FFM intervention trial was conducted in rural childbearing-aged women. Participants (n = 55) consumed one stalk of either FFM (treatment group) or ordinary maize (control group) daily. This dietary intervention lasted for 2 months, during which we assessed the participants' serum folate levels at baseline, mid stage (after 1 month), and final stage (after 2 months) to evaluate the health effect of FFM. We found that the serum folate level in the treatment group (13.31 ng/mL) was 3.40 ng/mL higher than that in the control group (9.91 ng/mL) in the final stage of the study. These findings suggest that regular dietary FFM intake significantly increased serum folate levels in rural Chinese women. Second, we further expanded our study by involving 181 local rural women with similar demographic characteristics to participate in a Becker–DeGroot–Marschak (BDM) bidding experiment to measure their WTPs for FFM. Results showed that local consumers were willing to pay 2.82 Chinese Yuan (CNY) per stalk of FFM, approximately 1.21 CNY higher than the price of ordinary maize. And women who participated in and completed the intervention trial had a higher preference for FFM during the evaluation. We provide evidence on the health improvement effect of biofortified foods and shed light on the associated consumer valuation and policy implementation.","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":"39 S1","pages":"1458-1477"},"PeriodicalIF":3.2,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136213286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several zinc interventions have been implemented worldwide to improve the public's zinc status, but limited studies have assessed their cost-effectiveness. To help inform decision-making on zinc interventions to maximize benefits within a fixed budget, we took China as an example and evaluated the cost-effectiveness of three interventions, that is, supplementation, food fortification, and biofortification. As an essential group at high risk of zinc deficiency, children aged 5–14 years, who account for 10% of the Chinese population, were selected as the target group in this study. We constructed a decision-analytic Markov model to determine the cost-effectiveness of interventions in China under different scenarios. In our model, biofortification through conventional breeding was shown to be the most cost-effective approach in most scenarios. Compared with other interventions, zinc supplementation gained fewer quality-adjusted life years at a higher net cost, suggesting that this common approach may not be optimal for large-scale, long-term implementation at the national level. While the robustness of the results was further confirmed by the sensitivity analysis, more research is needed to assess the cost-effectiveness of addressing zinc deficiency with other interventions. Further clinical trials are also expected to evaluate the effectiveness of zinc interventions in reducing pneumonia cases [EconLit Citations: I18, Q16, Q18].","PeriodicalId":55544,"journal":{"name":"Agribusiness","volume":"39 S1","pages":"1437-1457"},"PeriodicalIF":3.2,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136213295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a scarcity of empirical evidence linking these two aspects. The relationship between Internet usage and dietary quality remains inconclusive in both developed and developing countries. Using data from a survey of 2053 households in rural China, this paper examines the relationship between Internet usage and dietary quality among Chinese rural residents by employing an endogenous switching regression model to address the issue of selection bias. The empirical results reveal that respondents' gender, age, years of education, and household income significantly influenced their decisions to use the Internet, and Internet usage significantly improve dietary quality of their household. The findings of the heterogeneous analysis show that the impact of Internet usage on dietary quality varies based on respondents' dietary knowledge, per capita annual income, and household food expenditure. Through mechanism analysis, we find that Internet usage can improve the dietary quality by increasing the possibility of online food purchasing and fostering a more positive dietary attitude.

China introduced its first nationwide agricultural subsidy (i.e., the direct grain subsidy) for farmers in 2004. This study examines the impacts of direct grain subsidies on rural residents' food consumption patterns and nutritional intake on an individual basis. Based on a nationally representative sample of rural households from the National Rural Fixed Observation Points Survey data collected by the Ministry of Agriculture and Rural Affairs of China between 2003 and 2015, high-dimensional fixed-effects estimates show that the direct grain subsidy has boosted rural residents' grain consumption but reduced aquatic products, eggs, and dairy consumption in China. Specifically, an increase of 100 Chinese Yuan in per capita subsidies is associated with a rise of 14.94 g in daily grain consumption but a decrease of 0.57, 0.46, and 0.90 g in aquatic products, eggs, and dairy consumption, respectively. Furthermore, direct grain subsidies intensified rural residents' dietary imbalance and declined their dietary diversity. Observed dietary imbalance can be primarily attributed to the subsidy encouraging households' self-sufficient grain consumption, leading to excessive cereal consumption and relatively lower consumption of meat, eggs, and milk. Our findings suggest that direct grain subsidies emphasizing the production of staple grains may inadvertently skew farmers' food consumption and nutritional intake, which may require consideration when evaluating the overall costs and benefits of agricultural subsidy policies.

Imposing a “carbon tax on food” can be a very effective climate change mitigation policy and the ultimate distributional effect depends heavily on the way the tax is implemented. To offset the regressive financial effect, redistribution measures need to be designed and the financial welfare loss can serve as a first orientation for designing these redistribution measures. Current literature mainly uses estimated elasticities from empirical demand systems to approximate the welfare change which can lead to a substantial bias if the tax rate is sufficiently large. In contrast, we calculate the welfare change by using the Exact Consumer Welfare of a carbon tax on milk for selected emerging economies. We show that on average, consumers in upper-middle-income economies would face a financial welfare loss of 19.4–176.9 USD (in the value of 2017) measured by the compensating variation (CV), depending on the tax scenario. Among a set of 16 emerging economies, consumers in Argentina (ARG) and Türkiye (TUR) face the highest financial welfare losses. We also find that discrepancies between the Exact Consumer Welfare and the consumer surplus are very small.
