Several recent studies suggest that equalizing transfers in a federal system may distort the tax policy decisions of states. We study this issue for the German federal fiscal system. In a simple theoretical model, we first identify a substitution and an income effect of equalizing transfers. Our...

The German government provides discretionary investment grants to structurally weak regions to reduce regional disparities. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of receiving investment grants, to identify the causal effects of the...

This article investigates the effects of an increase in paid parental leave - twelve months instead of six months - on children's long-term life satisfaction. The historical setting under study, namely the former German Democratic Republic (GDR), allows us to circumvent problems of selection of...
