In this paper we incorporate a labor market with matching frictions and wage rigidities into the New Keynesian business cycle model. In particular, we analyze the effect of a monetary policy shock and investigate how labor market frictions affect the transmission process of monetary policy. The...

In theoretical literature, the effects of employment protection on unemployment are ambiguous. Higher employment protection decreases job creation as well as job destruction. However, in most models, wages are bargained individually between workers and firms. Using a conventional matching model...

Based on unique administrative data, which has only recently become available, this paper estimates the employment effects of the most important type of public sector sponsored training in Germany, namely the provision of specific professional skills and techniques (SPST). Using the inflows into...

We analyze the effectiveness of publicly financed training and retraining programs in east Germany as measured by their effects on individual re-employment probabilities after training. These are estimated by discrete hazard rate models on the basis of individual-level panel data. We account for...

We analyze the effectiveness of public works programs (PWP, Arbeitsbeschaffungsmaßnahmen) in east Germany as measured by their effects on individual future reemployment probabilities in regular jobs. These are estimated by discrete hazard rate models on the basis of individual?level panel data....

This paper investigates whether and in what sense the west German wage structure has been ?rigid? in the 1990s. To test the hypothesis that a rigid wage structure has been responsible for rising low-skilled unemployment, I propose a methodology which makes less restrictive identifying...

This paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labor markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labor market rigidities. In an...

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...

We analyze the employment effects of immigration within a model that accounts for several stylized facts of the German labor market. The co-existence of positive wage spans and unemployment is explained by wage rigidities that are simultaneously caused by effciency-wage setting and minimum...

This paper quantifies the impact of the Hartz reforms on matching efficiency, using monthly SOEP gross worker flows (1983-2009). We show that, until the early 2000s, close to 60% of changes in the unemployment rate are due to changes in the inflow rate (job separation). On the contrary, since...
