The impact of child welfare legislation on domestic violence‐related homicide rates
研究美国1996-2012年间儿童福利立法对家庭暴力相关杀人率的影响，发现立法显著降低了杀人率，但对婚姻内杀人无效，可能因报复风险抵消了威慑效果。
State-specific statutes providing legal consequences for perpetrating domestic violence in the presence of a child have been enacted across the United States between 1996 and 2012. This paper examines the impact of this child welfare legislation, using a difference-in-differences approach. We find a significant drop in domestic violence-related homicide rates, when considering a wide range of victim-offender relationships. However, this result does not hold for marital homicides, suggesting that for this subpopulation, the risk of reprisal and consequent reduction in reporting may be counterbalancing the hypothesized deterrent impacts of the legislation.
