Maternity leave and children's health outcomes in the long-term

This paper assesses the impact of the length of maternity leave on children's health outcomes in the long-run. My quasi-experimental design evaluates an expansion in maternity leave coverage from two to six months, which occurred in the Federal Republic of Germany in 1979. The expansion came into effect after a sharp cutoff date and significantly increased the time working mothers stayed at home with their newborns during the first six months after childbirth. Using this cutoff date as a source of exogenous variation, I exploit German hospital registry data, which contains detailed information on the universe of inpatients' diagnoses from 1995-2014. By tracking the health of treated and control children from age 16 up to age 35, this study provides new insights into the trajectory of health differentials over the life-cycle. I find that the legislative change generated positive long-term health effects: My intention-to-treat estimates show that children born after the implementation of the reform experience fewer hospital admissions and are less likely to be diagnosed with mental and behavioral disorders.
