It is common knowledge that the standard New Keynesian model is not able to generate a persistent response in output to temporary monetary shocks. We show that this shortcoming can be remedied in a simple and intuitively appealing way through the introduction of labor turnover costs (such as...

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...

We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this is sufficient to increase both, output and inflation persistence. -- Monetary persistence ; labor adjustment costs

This paper addresses the question of why high unemployment rates tend to persist even after their proximate causes have been reversed (e.g., after wages relative to productivity have fallen). We suggest that the longer people are unemployed, the greater is their cumulative likelihood of falling...

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 highunemployment regions have fallen relative to those in the low-unemployment regions). We suggest that the...
