Abstract Based on a structural model of fertility and female labour force supply with unobserved heterogeneity and state dependence, we evaluate the 2007 reform of parental leave benefits in Germany, which replaced a flat, means-tested benefit by a generous earnings-related transfer. The model predicts a short-term fertility effect of about 4%, which is consistent with recent quasi-experimental evidence. The fertility effect is strongest for first births and increases with income. We use the model for a number of counterfactual policy experiments in which we vary the generosity of parental leave benefits.

1 Introduction Almost all OECD countries have a system of paid parental leave in place. During parental leave, parents are guaranteed their pre-birth jobs and typically receive some kind of financial support. Countries differ in the duration of parental leave and the level and design of benefit payments (Thévenon and Solaz 2013). In 2007, Germany, which had long been a classic example of a “male breadwinner” model, took many observers by surprise and reformed its parental leave regulations to bring them closer to the “Nordic model”. By shortening the entitlement period from 24 to 12 months (14 months if both parents go on parental leave for at least two months), the
