AbstractI estimate whether the ability to anonymously surrender an infant to a safe haven site such as a hospital, police station, or fire station in the United States affects child well‐being. By analyzing variation in state safe haven policies, I find safe haven laws significantly increase infant foster care entrance. I further find suggestive evidence of safe havens reducing infant deaths. The mortality effects are immediate but subside over time, implying infants have been relinquished when their alternative was not death from abuse or abandonment. Robustness checks and falsification tests support these findings.
