This paper studies wage effects and job mobility as a result of skill mismatch in worker- occupation pairs. I develop a Roy model in which learning on the job induces workers to shift more time towards job-specific activities. Using a short task panel containing data on worker’s time...

This paper analyzes the effect of educational mismatch on wages in Germany, using data from the German Socio-Economic Panel. Educational mismatch has been discussed extensively, mostly by applying OLS wage regressions which are prone to an unobserved heterogeneity bias. This problem is...

This study investigates whether foreign origin teachers causally affect their students language skills in secondary school. Exploring within-student variation in assignment to teachers, I find that teachers who are immigrants or descendants of immigrants significantly increase the reading...

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...

Increasing mothers’ labor supply is a key policy challenge in many OECD countries. Germany recently introduced a generous parental benefit that allows for strong consumption smoothing after childbirth and, by taking into account opportunity costs of childbearing, incentivizes working women to...

Using a semi-structural approach based on a dynamic monopsony model, we examine to what extent workers performing different job tasks are exposed to different degrees of monopsony power, and whether these differences in monopsony power have changed over the last 30 years. We find that workers...

Occupational mismatch is a wide-spread phenomenon among immigrants in many European countries. Mismatch, predominantly measured in terms of education, is often regarded as a waste of human capital. Such discussions, however, ignore the imperfect comparability of international educational degrees...

We propose a new explanation for differences and changes in labor supply by gender and marital status, and in particular for the increase in married women's labor supply over time. We argue that this increase as well as the relative constancy of other groups' hours are optimal reactions to...

Over the last decades fertility rates have decreased in most developed countries, while female labour force participation has increased strongly over the same time period. To shed light on the relationship between women's fertility and employment decisions, we analyse their transitions to the...
