Infant Health and Later-Life Labor Market Outcomes
利用瑞典1968-2012年全人口纵向数据，研究1930年代末磺胺吡啶治疗肺炎对婴儿健康的改善如何影响成年后的劳动力市场结果，发现婴儿期肺炎感染减少使成年劳动收入提高2.8-5.3%。
This paper studies the effects of improvements in infant health produced by the introduction of sulphapyridine in the late-1930s as treatment against pneumonia on outcomes in adulthood. Based on longitudinal individual data for the whole population of Sweden 1968–2012 and archival data on the availability of sulphapyridine and applying a difference-in-differences approach, it finds that mitigation of pneumonia infection in infancy increased labour income in late adulthood by 2.8–5.3 percent. The beneficial effects are strong for health, measured by length of stay in hospital, and weaker for years of schooling. These effects are similar between men and women.
