**Abstract**
In this paper, we present a model of a one-parent, one-child household where parental decisions on labor supply, leisure, and the demand for parental and public child care are simultaneously endogenized and intertemporally determined. We characterize the path of the optimal decisions and investigate the effects of various public child care fees and of the quality of public child care services on the parent’s time allocation and the child’s performance level. Our results show that different public child care policies may induce substantially diverging effects and reveal that each policy frequently faces a trade off between an encouragement of labor supply and an enhancement of the child’s performance. In addition, we find that, from an efficiency perspective, an income-based fee levied on public child care services is dominated by both a flat fee and a use-based fee system.
