The distribution of unemployment duration in our equilibrium matching model with spell-dependent unemployment benefits displays a time-varying exit rate. Building on Semi-Markov processes, we translate these exit rates into an expression for the aggregate unemployment rate. Structural estimation...

Der Beitrag evaluiert die Wirkungen eines Betreuungsgeldes bei gleichzeitigem Ausbau der öffentlich geförderten Tagesbetreuung für Kinder im Alter von 13 bis 36 Monaten. Wir schätzen mit SOEP-Daten und unter Berücksichtigung partiell beobachtbarer Rationierungen im Betreuungsbereich ein...

German family policy underwent a reform in 2007, when the new instrument of "Elterngeld" replaced the previous "Erziehungsgeld". The transfer programs differ in various dimensions. We study the effects on the labor supply of young mothers, by comparing behavior before and after the reform. We...

This paper contributes to the debate about the optimal design of tax-transfer systems. Based on the theory of optimal taxation, combined with microsimulation and microeconometric techniques we derive the welfare function which makes the current German tax and transfer system for single women...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non-separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...

We analyze empirically the optimal design of social insurance and assistance programs when families obtain insurance by making labor supply choices for both spouses. For this purpose, we specify a structural life-cycle model of the labor supply and savings decisions of singles and married...
