The distribution of unemployment duration in our equilibrium matching model with spell-dependent unemployment benefits displays a time-varying exit rate. Building on Semi-Markov processes, we translate these exit rates into an expression for the aggregate unemployment rate. Structural estimation...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

This work refers to analyses of matching processes on occupational labour markets in Germany. Up to now, all studies in this field are based on the crucial assumption of separate occupational labour markets. I outlined some theoretical considerations that occupational markets are probably not...

There is an ongoing discussion that centres on the German labour market reforms (2003- 2005) and the role of these reforms in boosting the German economy. Considering that one of the main objectives of the reforms was to improve the matching process on the labour market, I use rich,...

Our search model combines two search methods, the public employment service (PES) and random search. The separation rate is endogenous, the job matching process consists of three rounds. In the first and the second respectively the short-term (STU) and the long-term unemployed (LTU) randomly...

The search model contains two matching technologies, the public employment service (PES) with its type-specific registers for workers and vacancies, and the search market where firms advertise vacancies and unemployed who have not been placed by the PES search for jobs. The placement activity of...

This paper studies optimal taxation schemes for education in a search-matching model where the labor market is divided between a high-skill and a low-skill sector. Two public policy targets - maximizing the global employment level and optimizing the social surplus - are studied according to...

Not only the level of aggregate unemployment but also the properties of its dynamics are an important topic in macroeconomics and labor economics. Several models like e.g. matching models with endogenous job destruction explicitly predict an asymmetric pattern in the evolution of unemployment,...

The role of the 2000’s German labour market reforms in boosting the German economy has been widely discussed. Considering that one of the main objectives of these reforms was to improve the matching process on the labour market, I use high-frequency administrative data to present new details...
