The Dynamic Interdependence of Women′s Employment and Fertility

Research on the causal relationship between women′s fertility and their employment patterns has yielded contradictory findings. In order to shed some light on the confusion that has resulted, hazard models are used to investigate the possibility these two variables are dynamically interdependent. Transition rates among combined states of pregnancy and fertility are analyzed for a data set consisting of joint work and fertility event histories for a national sample of young white and black women. The results lend support to the interdependence thesis. Pregnancy and motherhood increase the rate at which women leave employment and decrease their reentry rate. Furthermore, I find that women′s wages, and for white women, employment status as well, are negatively and significantly related to their rate of becoming pregnant.
