On the Quantity and Quality of Girls: Fertility, Parental Investments and Mortality
研究发现印度产前性别检测技术导致大量女胎流产，但存活女孩的死亡率性别差距缩小，表明她们比被流产的女孩更受欢迎，同时父母投资和生育行为也发生变化。
Abstract Access to prenatal sex-detection technology in India has led to a phenomenal increase in abortion of girls. We find that it has also narrowed the gender gap in under-five mortality, consistent with surviving girls being more wanted than aborted girls. For every three aborted girls, one additional girl survived to age five. Mechanisms include moderation of son-biased fertility stopping and narrowing of gender gaps in parental investments. However, surviving girls are more likely to be born in lower-status families. Our findings have implications not only for counts of missing girls but also for the later life outcomes of girls.
