Parental Leave Policies and Socio-Economic Gaps in Child Development : Evidence from a Substantial Benefit Reform Using Administrative Data

Abstract

This paper examines the effects of substantial changes in paid parental leave on child development and socio-economic development gaps. The authors exploit a German reform from 2007 that both expanded paid leave in the first year and removed paid leave in the second year following childbirth. Higher-income households benefited relatively more from the reform than low-income households. They use administrative data from mandatory school entrance examinations containing detailed child development assessments at age six within a difference-in-differences approach. Their precise and robust estimates reveal no effects of the changes in parental leave benefits on child development across various socio-economic groups, and consequently no effects on socio-economic development gaps.
