In this paper I investigate the causal returns to education for different educational groups in Germany by employing a new method by Klein and Vella (2010) that bases identification on the presence of conditional heteroskedasticity. Compared to IV methods, key advantages of this approach are...

The central limit theorem says that, provided an estimator fulfills certain weak conditions, then, for reasonable sample sizes, the sampling distribution of the estimator converges to normality. We propose a procedure to find out what a “reasonably large sample size” is. The procedure is...

Despite the increasing incidence of part-time employment in Germany, the effects on wage rates are studied rarely. I therefore use SOEP panel data from 1984 to 2010 and apply different econometric approaches and definitions of part-time work to measure the socalled part-time wage gap of both,...

We estimate the impact of a differential treatment of paid employees versus self-employed workers in a public health insurance system on the entry rate into entrepreneurship. In Germany, the public health insurance system is mandatory for most paid employees, but not for the self-employed, who...

While most studies on wealth inequality focus on the inequality between households, this paper examines the distribution of wealth within couples. For this purpose, we make use of unique individual level micro data from the German Socio-Economic Panel (SOEP). In married and cohabiting couples,...

There is little known about the effects of staggered-hours programs that affect workers' working schedules to mitigate peak congestion. We examine the effect of workers' morning start times on their wages for Germany. In contrast to previous work based on cross-section data, we demonstrate that...

In Germany, researchers dealing with questions of empirical educational research rely mainly on cross-sectional data. In addition, there are region- and group-specific longitudinal studies. This paper demonstrates the possibilities for using educationally relevant information from long-running...

In this paper, we compare different approaches to the generation of datasets linking employees and firms, and present the specific advantages and disadvantages of each method. We discuss in detail the employee-first method, which has only been investigated so far in the survey research in...

Das Sozio-oekonomische Panel (SOEP) ist als multidisziplinäres Haushaltspanel, das Informationen zu allen Personen, die in einem Panel-Haushalt leben, erhebt und damit alle Altersjahrgänge abdeckt, nach 25 Jahren Laufzeit auch zu einer Kohorten- Studie geworden. Der zunehmende Erfolg der...

Bargaining theory suggests that married women who experience a relative improvement in their labour market position should experience a comparative gain within their marriage. However, if renegotiation possibilities are limited by institutional mechanisms that achieve long-term commitment, the...
