Mothers' and Fathers' Labor Supply in Fragile Families: The Role of Child Health

We estimate the effect of poor child health on the labor supply of mothers and fathers post welfare reform, using a national sample of mostly unwed parents and their children-a group at high risk of living in poverty. We account for the potential endogeneity of child health and find that having a young child in poor health reduces the mother's probability of working, the mother's hours of work, and the father's hours of work. These results suggest that children's health problems may diminish their parents' capacity to invest in their health.
