A09 aims at informing policymakers about family policy reforms. The optimal design of such reforms requires knowledge about (a) behavioral responses of individuals to the incentives provided and (b) societal preferences for redistribution. The first two parts of this project contribute to the growing literature on family policies along these two dimensions. First, we study the implications of parental leave duration and parental leave benefits for labor market behavior of mothers. Second, the project team will conduct survey experiments (based on SOEP-IS) to analyze determinants of inequality and fairness perceptions as well as preferences for redistribution, with a special focus on family related policies. Building on these insights, the PIs will analyze the optimal design of policy reforms in the third part.
