Generous income support programs as provided by European welfare states have often been blamed to reduce work incentives for lower income classes and to increase durations of unemployment. Standard studies measure work incentives based on annual income concepts. This paper analyzes how work...

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...

This paper quantifies the impact of the Hartz reforms on matching efficiency, using monthly SOEP gross worker flows (1983-2009). We show that, until the early 2000s, close to 60% of changes in the unemployment rate are due to changes in the inflow rate (job separation). On the contrary, since...

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 distributive justice of the combined burden of taxes, social security contributions and public transfers on employee households. In order to investigate whether the treatment of families by the aggregate tax-benefit system can be regarded as "fair" we compare the equivalent...
