Individuals with more years of education generally acquire more training later on in life. Such a relationship may be due to skills learned in early periods increasing returns to educational investments in later periods. This paper addresses the question whether the complementarity between...

With increasing educational attainment in Germany, the issue of inefficient human capital allocation gains importance. Especially overeducation seems to be a problem, since more and more highly educated individuals are required to take jobs that do not match their educational level, settling for...

In this paper, we identify female long-term wage returns to college education using the educational expansion between 1960-1990 in West Germany as exogenous variation for college enrollment. We estimate marginal treatment effects to learn about the underlying behavioral structure of women who...

The automation of work tasks due to technological change increases the pressure on employees whose workplaces consist largely of such activities. Further training is an important way of adapting skills and enabling the performance of tasks that cannot be automated and are required in modern...

Do returns to training differ if training is accompanied by technological innovations at the workplace? We analyze this potential heterogeneity of returns based on panel data from Germany that provide a unique measure for individuals' adoption of new technology at the workplace. In the preferred...

This paper analyzes the returns to training that was co-financed by the German voucher program "Bildungsprämie". The estimation strategy compares outcomes of participants in voucher training with voucher recipients who intended to participate in training, but did not do so because of a random...

In this paper, we investigate sibling correlations in educational outcomes, which serve as a broad measure of the importance of family and community background. Making use of rich longitudinal survey and register data for Denmark, our main aim is to identify the parental background...

In this article, we analyze whether non-native speakers in the classroom affect the educational achievement and social integration of migrant and native students. In contrast to previous studies, which mainly examine the effect of the share of immigrant pupils, we focus on language heterogeneity...

While randomized controlled trials (RCTs) are the 'gold standard' for impact evaluation, they face numerous practical barriers to implementation. In some circumstances, a randomized-encouragement design (RED) is a viable alternative, but applications are surprisingly rare. We discuss the...

This study is the first empirical analysis to identify the causal effect of a separate preparatory language learning class on the academic success of newly immigrated primary school-aged children in comparison to their direct integration into regular classrooms. Employing unique administrative...
