Birth Weight in the Long Run
利用1926-1958年瑞典双胞胎数据与终身行政记录，研究发现出生体重正向影响永久收入和生命周期大部分阶段的收入，且该效应在相隔30年的队列中相似。
We study the effect of birth weight on long-run outcomes using data on Swedish twins born between 1926 and 1958 linked to administrative records spanning entire life-time labor market histories. We find that birth weight positively affects permanent income and income across large parts of the lifecycle. The timing of the birth weight–income relationship is in line with the role of birth weight in determining takeup of sickness benefits and morbidity. The effect of birth weight on labor market outcomes even for cohorts born 30 years apart are similar; for short run health outcomes, birth weight plays a decreasing role over time.
