Infant Health, Cognitive Performance, and Earnings: Evidence from Inception of the Welfare State in Sweden
利用瑞典行政数据，研究婴儿健康干预对长期收入的影响，发现干预提高了小学成绩，但只有女孩在中学、就业和收入上获益，且收益来自技能和机会两方面。
Abstract We identify earnings impacts of exposure to an infant health intervention in Sweden, using individual-linked administrative data to trace potential mechanisms. Leveraging quasi-random variation in eligibility, we estimate that exposure was associated with higher test scores in primary school for boys and girls. However, only girls were more likely to score in the top quintile. Subsequent gains, in secondary schooling, employment, and earnings, are restricted to girls. We show that the differential gains for women accrued from both skills and opportunities.
