中文摘要
印度2013年《国家粮食安全法》(NFSA)促成了历史上规模最大的粮食转移扩张之一，影响超过5亿人。我们利用NFSA产生的看似外生的变异，估计粮食转移对儿童营养的影响。基于印度八个邦五年间的个体面板数据，我们发现增加的粮食转移显著降低了儿童生长迟缓。粮食转移提高了工资收入，并改善了膳食多样性。我们的结果表明，在我们研究的各邦，NFSA使约180万名儿童避免了生长迟缓。(JEL I12, I18, I38, J13, O12)
Abstract
India's National Food Security Act of 2013 (NFSA) led to one of the biggest expansions in food transfers in history, affecting over 500 million people. We use plausibly exogenous variation created by the NFSA to estimate the effect of food transfers on child nutrition. Using individual panel data across eight states in India over five years, we find that increased transfers significantly reduced stunting. The food transfers increased wage incomes and improved dietary diversity. Our results suggest that, in the states we study, the NFSA prevented approximately 1.8 million children from being stunted (JEL I12, I18, I38, J13, O12)
