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...

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

This paper indicates that East Germany’s unemployment originates primarily in the labor market, caused by the fast wage adjustment after German reunification. We model the resulting labor market traps in a search and matching framework, show that they are difficult to overcome, and provide...

This paper addresses the question of why prolonged regional unemployment differentials tend to persist even after their proximate causes have been reversed (e.g., after wages in the high-unemployment regions have fallen relative to those in the low-unemployment regions). We suggest that the...

This paper analyzes the effects of different labor market institutions on inflation and output volatility. The eurozone offers an unprecedented experiment for this exercise: since 1999, no national monetary policies have been implemented that could account for volatility differences across...

This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

This paper analyses theoretically and empirically how employment subsidies should betargeted. We contrast measures involving targeting workers with low incomes/abilities andtargeting the unemployed under the criteria of "approximate welfare efficiency" (AWE)...

This paper provides a theoretical and quantitative analysis of various types of wellknown employment subsidies. Two important questions are addressed: (i) How should employment subsidies be targeted? (ii) How large should the subsidies be? We consider measures involving targeting workers with...

In a perfect labor market severance payments can have no real effects as they can beundone by a properly designed labor contract (Lazear 1990). We give empirical content tothis proposition by estimating the effects of EPL on entry wages and on the tenure-wageprofile in a quasi-experimental...

We study the relationship between employment growth and worker flows in excess of job flows (churn) at the establishment level using the new German AWFP dataset spanning from 1975–2014. Churn is above 5 percent of employment along the entire employment growth distribution and most pronounced...
