Why are female entrepreneurs so rare? Women have both to a lower entry rate into self-employment and a higher exit rate in Germany. To explain the gender gap, a structural microeconometric model of the transition rates is estimated, which includes a standard risk aversion parameter. As inputs...

There is by now a lot of evidence showing a sharp increase in cross-sectional wage and earnings inequality during the 2000s in Germany. Our study is the first to decompose this cross-sectional variance into its permanent and transitory parts for years beyond 2000. Using data from the German...

Several empirical minimum wage studies have recently been published that simulate employment effects of a federal minimum wage in Germany. We disentangle various factors that explain the variation in previous simulation results. Based on data from the German Socio-Economic Panel and the newly...

The current economic crisis requires fast information to predict economic behavior early, which is difficult at times of structural changes. This paper suggests an innovative new method of using data on internet activity for that purpose. It demonstrates strong correlations between keyword...

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...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

Based on a theoretical framework on informal, custodial and non-custodial sentencing, the paper provides econometric tests on the effectiveness of police, public prosecution and courts. Using a unique dataset covering German states for the period 1977- 2001, a comprehensive system of criminal...
