The Effect of Child Care Costs on Married Women's Labor Force Participation
估计了育儿成本对已婚有子女女性劳动参与概率的影响，发现育儿成本上升会降低参与概率，且学龄前儿童母亲参与率低完全源于更高的育儿成本。
The effect of child-care costs on the probability that married women with children will participate in the labor market is examined. Child-care costs are estimated.using a generalized Tobit specification corrected for selection. Estimates of a structural probit model of labor-force participation provide evidence to support the prediction that increased child-care costs lower the probability of participation. It is also shown that the lower rate of labor-force participation among mothers of preschoolers is entirely the result of the higher child-care costs faced by these women and endogeneity of the number of young children in the participation equation.
