Spillover Effects of Early-Life Medical Interventions
利用丹麦行政数据和断点回归设计，研究极低出生体重婴儿的早期医疗干预如何改善其健康与学业，并发现母亲心理健康和兄弟姐妹学业也受益。
Abstract We investigate the effects of early-life medical treatments on the treated children and their families. We use a regression discontinuity design that exploits changes in medical treatments across the very low birth weight (VLBW) cutoff. Using administrative data from Denmark, we establish that VLBW children have better health and higher test scores. We find that these benefits spill over to other family members: mothers enjoy better mental health, and siblings have higher test scores. Maternal mental health improvements seem to be driven by better focal child health and sibling spillovers by improved interactions within the family and parental compensating behavior.
