In this paper we estimate an intertemporal structural model of labor supply for mothers with young children. In order to validate the structural model, we make use of a recently introduced parental leave reform in Germany. We compare the behavioral predictions of the structural model under the reform (out-of-sample fit) to results based on an evaluation where we exploit the parental leave reform as a natural experiment. Based on both methods we find that due to the new parental leave scheme, that pays higher benefits for a shorter period of time, labor supply of mothers in the first year after giving birth declines, however increases in the second year. Further, we find the strongest effects for low-income mothers, who have a significantly higher probability to return to work two years after giving birth than under the old parental leave scheme. Overall our findings support a policy evaluation based on the structural model since despite the imposed structural assumptions the model can replicate the causal effect of a real policy reform.
