How skills acquired in vocational education and training (VET) affect wages and employment is not clear. We develop and estimate a search and matching model for workers with a VET degree. Workers differ in interpersonal, cognitive and manual skills, while firms require and value different...

Using high-quality administrative data, I analyze workers' opportunity costs of reallocation across occupations by measuring the additional time spent in unemployment before being hired in a new occupation. Furthermore, I inspect the wage changes after reallocation and find that workers who...

This paper shows that the matching function and the Beveridge curve in the United States exhibit strong nonlinearities over the business cycle. These patterns can be replicated by enhancing a search and matching model with idiosyncratic productivity shocks for new contacts. Large negative...

This paper evaluates the effects of policy interventions on sectoral labour markets and the aggregate economy in a business cycle model with search and matching frictions. We extend the canonical model by including capital-skill complementarity in production, labour markets with skilled and...

Das Hamburger Modell zur Beschäftigungsförderung zielt darauf ab, Arbeitslose mit geringen Verdienstmöglichkeiten und schlechten Arbeitsmarktchancen durch zeitlich befristete Zuschüsse, die sowohl den Teilnehmern an der Maßnahme als auch den Arbeitgebern gewährt werden, in den regulären...

In this paper we examine how employment and hiring processes develop in the course of digitalisation in German establishments. To this end we use a large representative business survey - the IAB Job Vacancy Survey - that was extended in 2015 to include special questions about the state of...

We estimate spatially heterogeneous effects of the COVID-19 pandemic on labour market dynamics in Germany until December 2021. While initially slightly larger in rural regions, adverse effects quickly become more pronounced and persistent in large agglomerations. We ascribe the larger impact of...

We revisit the puzzling finding that labour market performance appears to deteriorate, as suggested by negative time trends in empirical matching functions. We investigate whether these trends simply arise from omitted variable bias. Concretely, we consider the omission of job seekers beyond the...

This paper analyzes the importance of time aggregation in the measurement of worker flows by exploiting daily information from German administrative data. Time aggregation caused by comparing monthly labor market states leads to an underestimation of total worker flows by around 10%. Contrary to...

Does the low wage sector serve as a stepping stone towards integration into better-paid jobs or at least towards integration of jobless people into employment? There is evidence for a 'low-wage trap' and for a high risk of low-wage earners to get unemployed, but this may also be due to sorting...
