Paid Parental Leave Policies and Infant Mortality Rates in OECD Countries: Policy Implications for the United States

Infant mortality is an important indicator of a nation's overall health and well-being because of its association with education, availability and accessibility of health services, and income inequality. In this paper, we examine the effect of job-protected paid parental leave on infant and post-neonatal mortality rates in 19 OECD countries from 1960 to 2012. We utilize a generalized least squares model controlling for a host of variables traditionally examined in studies of infant mortality rates, as well as year fixed effects, country fixed effects, and country time trends. We find a statistically significant association between job-protected paid parental leave and a reduction in both infant mortality rates and post-neonatal mortality rates. The findings are particularly relevant for policymakers in the United States, the only industrialized democracy in the world that does not provide job-protected paid parental leave to working women and men.
