Poverty, Violence, and Health: The Impact of Domestic Violence During Pregnancy on Newborn Health
研究发现孕期遭受家庭暴力会显著降低新生儿出生体重，且贫困和少数族裔女性受害更重，揭示了暴力对健康的负外部性。
Two percent of women in the US suffer from intimate partner violence annually, with poor and minority women disproportionately affected. I provide evidence of an important negative externality associated with domestic violence by estimating a negative and causal relationship between violence during pregnancy and newborn health, exploiting variation in the enforcement of laws against domestic violence for identification. I find that hospitalization for an assault while pregnant reduces birth weight by 163 grams. This sheds new light on the infant health production process as well as observed income gradients in health given that poor mothers are disproportionately affected by violence.
