This study analyses the persistence and true state dependence of overqualification, i.e. a mismatch between workers' qualifications and their jobs’ educational requirements. Employing individual-level panel data for Germany, I find that overqualification is highly persistent among tertiary...

Graduates from Science, Technology, Engineering, and Mathematics (STEM) are usually found to have higher wages and a lower risk of overqualification. However, it is unclear whether we can interpret the effect of STEM subjects on overqualification and wages in a causal way, since individuals...

We investigate the effect of peer group composition on language improvement in language classes for adults. Using unique survey data of migrants participating in an intensive language course in Germany, we find that the age and skill composition of groups affect skill acquisition as assessed by...

Self-productivity is a crucial feature in the process of skill formation. It means that skills and health acquired at one stage in the life cycle enhance skills and health formation at later stages. This paper presents an empirical investigation of self-productivity in early childhood in...

Based on a large data set containing information on occupations between 1979 and 1999, this study explores the "black box" surrounding the skill-biased technological change hypothesis by analyzing the mechanisms that induce information technologies to be complementary to employees with higher...

This paper analyses the link between educational attainment and unemployment risk in a French-German comparison, based on a discrete time competing risks hazard rate model applied to comparable microdata sets. The unemployment risk is broken down into the risk of entering unemployment and the...

This paper evaluates the effects of a major Swedish school choice reform. The reform in 1992 increased school choice and competition among public schools as well as through a large-scale introduction of private schools. We estimate the effects of school choice and competition, using precise...
