Child Gender and Parental Investments In India: Are Boys and Girls Treated Differently?
利用性别在受孕时随机的识别策略，研究发现印度农村男孩比女孩获得更多育儿时间、更长的母乳喂养和更多维生素补充，且身高体重优势大于其他发展中国家。
Previous research has not always found that boys and girls are treated differently in rural India. However estimates of the effect of gender on parental investments could be biased if girls end up in larger families due to son-biased stopping rules. Using a novel identification strategy that exploits that gender at conception is random, we document that boys receive more childcare time than girls, they are breastfed longer and they get more vitamin supplementation. Compared to other developing countries, boys have an advantage in height and weight relative to girls. Neither greater needs nor anticipated family size explain the results.
