Over the 2000s, many federal states in Germany shortened the duration of secondary school by one year while keeping the curriculum unchanged. Exploiting quasi-experimental variation due to the staggered introduction of this reform allows me to identify the causal effect of increased learning...

Studies on the underlying mechanisms of social mobility commonly find that half of the intergenerational earnings persistence remains unexplained. Focusing on the phenomenon of overqualification, this study examines a transmission channel that might operate beyond the mechanisms previously...

This paper analyses the risk of unemployment, unemployment duration and the risk of long-term unemployment immediately after apprenticeship graduation. Unemployed apprenticeship graduates constitute a large share of unemployed youth in Germany but unemployment incidence within this group is...

This paper jointly analyses the consequences of adverse selection and signalling on entry wages of skilled employees. It uses German linked employer employee panel data (LIAB) and introduces a measure for relative productivity of skilled job applicants based on apprenticeship wages. It shows...

Distinguishing carefully between mobility across firms and across occupations, this study provides causal estimates of the wage effects of mobility among graduates from apprenticeship in Germany. Our instrumental variables approach exploits variation in regional labor market characteristics....

This paper studies heterogeneity in schooling decisions by socio-economic status (SES) in response to a repeal of achievement-based admissions requirements (i.e. binding track recommendations) in Germany's between-school tracking system. The main contribution is to show that while previously...

This paper addresses the puzzle how employers that invest in general human capital can gain an information advantage with respect to the ability of their employees when training is certified by credible external institutions. We apply an established model from the employer-learning literature...

The paper provides empirical evidence for the question whether firms' ITenabled labour productivity is affected by the age structure of the workforce. We apply a production function approach with heterogenous labour to firmlevel data from German manufacturing and services industries. We find...

This paper studies the question whether skill-biased technical change diffuses internationally and that way contributes to the increasing relative skill demand in other countries. So far, the role of skill-biased technology diffusion has hardly been studied empirically. Using new sectoral data...

Firms invest huge amounts into intangible assets. This paper explores to which extent different kinds of intangible assets are conducive to firm-level productivity. Our study contributes to the literature by simultaneously comparing productivity effects of innovative capital, human capital,...
