While uncertainty abounds in almost any decision on investment in schooling, it is mostly ignored in research and virtually absent in labour economics text books. This paper documents the scope for risk, discusses the tough disentanglement of heterogeneity and risk, surveys the analytical...

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...

Using linked employer-employee panel data for Germany, this paper investigates whether firms implement real wage reductions in a selective manner. In line with insider-outsider and several strands of efficiency wage theory, we find strong evidence for selective wage cuts with high-productivity...

The paper provides a theoretical foundation for the empirical regularities observed in estimations of wage consequences of overeducation and undereducation. Workers with more education than required for their jobs are observed to suffer wage penalties relative to workers with the same education...

Using linked employer-employee panel data for Germany, this paper investigates whether firms implement real wage reductions in a selective manner. In line with insider-outsider and several strands of efficiency wage theory, we find strong evidence for selective wage cuts with high-productivity...

This paper for the first time jointly analyses the consequences of adverse selection, signalling and indices 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...

Firms hiring fresh graduates face uncertainty on the future productivity of workers. Theory suggests that starting wages reflect this, with lower pay for greater uncertainty. We use the dispersion of exam grades within a field of education as an indicator of the unobserved heterogeneity that...

How valuable are cognitive and social abilities for entrepreneurs’ incomes as compared to employees? We answer three questions: (1) To what extent does a composite measure of ability affect an entrepreneur's earnings relative to employees? (2) Do different cognitive abilities (e.g. math...

Small average wage effects of employer and/or occupation changes after apprenticeship training mask large differences between occupation groups and apprentices with different schooling back-grounds. Apprentices in commerce and trading occupations strongly profit from an employer change. Employer...

Low-skilled workers enjoy a large wage advantage in German works council establishments. Since job tenure is also longer for these workers, one explanation might be rent-seeking. If the premium is a compensating wage differential (or a return to unmeasured ability), it should not lead to higher...
