This paper demonstrates that insiders can erect barriers to entry and skim rents by sinking costs in human capital when labour markets are otherwise perfectly contestable. The sunk costs nature of human capital investments may result from the need to satisfy ever increasing specialised skill...

While there is a broad literature on the general wage effect of training, little is known about the effects of different training forms and about the effects for heterogeneous training participants. This study therefore adds two aspects to the literature on earnings effects of training. First,...

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....

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...

This paper investigates the effect of the size of the local labor market on skill mismatch. Using survey data for Germany, I find that workers in large cities are both less likely to be overqualified for their job and to work in a different field than the one they are trained for. Different...

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...

In Deutschland werden vielfach hohe Anforderungen an die berufliche Qualifikation von Existenzgründern gestellt. Im Handwerk, aber auch in bestimmten freiberuflich organisierten Tätigkeitsbereichen sind Existenzgründungen nur mit einem qualifizierten Berufsabschluß möglich. Darüber hinaus...

We analyze wage developments in the East German transition process both at the macro and at the microeconomic level. At the macroeconomic level, we draw special attention to the important distinction between product and consumption wages, describe the development of various wage measures, labor...

In this paper the impact of working hours on the gross hourly wage rate of West German women is analyzed. We use a simultaneous wage-hours model which takes into account the participation decision. First, our estimates show that the hourly wage rate is strongly a¤ected by the working hours. In...

The US labour market is characterized by a high skill wage mark-up and low unemployment, while the German labour market has a low skill wage mark-up and a high, mainly unskilled unemployment rate. This paper adds an innovative labour supply explanation to the discussion how these distinct labour...
