This paper examines job polarization at the level of local labor markets in Germany over a 30-year period. The major explanation of job polarization is skill biased technological change (SBTC): new technologies are complementary to high paying jobs but substitute workers in routine manual jobs...

Skill-Biased Technical Change is one of the most prominent explanations for the rise in wage inequality in the United States over the last decades. However, the explanation is challenged for several reasons. In this paper, I propose an alternative type of technical change, where new technologies...

We study the relationship between cyclical job and worker flows at the plant level using a new data set spanning from 1976-2006. We find that procyclical labor demand explains relatively little of procyclical worker flows. Instead, all plants in the employment growth distribution increase their...

This paper develops a labour market matching model with heterogeneous firms, on-thejob search and referrals. Social capital is endogenous, so that better connected workers bargain higher wages for a given level of productivity. This is a positive effect of referrals on reservation wages. At the...

In light of the remarkable number of young people who pass through a period of temp work at the beginning of their career the question arises whether labor market entry via temporary work agency (TWA) employment has any (persistent) effects on labor market outcomes. We investigate this issue...

This paper analyzes wage assimilation of ethnic German immigrants to Germany. We use unique administrative data that include a standardized measure of immigrants' pre-migration wage based on occupation, industry, tenure, qualification, and the German wage structure. We find that immigrants...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

This paper looks inside the firm and investigates how trade alters the matching of worker-specific abilities and task-specific requirements. The outcome of this matching depends on how firms organize their recruitment process and how much they invest into the screening of applicants. In the open...

When workers send applications to vacancies they create a bipartite network. Coordination frictions arise if workers and firms only observe their own links. We show that those frictions and the wage mechanism are in general not independent. Only wage mechanisms that allow for ex post competition...
