摘要

采用分阶段研究设计，我们提供了实验证据，证明在印度的学校午餐计划中，早开始和晚开始强化铁对儿童健康和认知结果的影响。我们发现，与接受1年半治疗的晚期治疗组相比，接受4年治疗的早期治疗组血红蛋白水平较高，贫血的可能性较低。尽管有显著的健康收益，但我们没有发现治疗对认知和教育结果有影响的证据。异质性分析显示了性别影响的证据——女性的贫血减少率比男性低。

Medium-Run Impacts of Iron-Fortified School Lunch on Anaemia, Cognition, and Learning Outcomes in India*

Using a phase-in research design, we provide experimental evidence on the impacts of early versus late initiation of iron fortification in school lunch programmes on children's health and cognitive outcomes in India. We find higher haemoglobin levels and a lower likelihood of anaemia in the early treatment group that experienced 4 years of treatment, compared to the late treatment group that was exposed to one and a half years of treatment. Despite significant health gains, we do not find evidence for treatment effects on cognitive and educational outcomes. Heterogeneity analyses show evidence of gendered effects – the anaemia reduction is lower among females relative to males.

期刊介绍： Whilst the Oxford Bulletin of Economics and Statistics publishes papers in all areas of applied economics, emphasis is placed on the practical importance, theoretical interest and policy-relevance of their substantive results, as well as on the methodology and technical competence of the research. Contributions on the topical issues of economic policy and the testing of currently controversial economic theories are encouraged, as well as more empirical research on both developed and developing countries.
