This paper introduces productivity-dependent firing costs into an otherwise standard endogenous separations matching model. We suggest an alternative to the standard fix cost approach and account for empirical evidence emphasizing that firing costs vary across workers. We show that the model...

We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this increases output persistence in a similar vein as other models of labor market frictions. Furthermore, it is demonstrated that quadratic labor adjustment costs imply...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

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...

We develop and estimate a general equilibrium model in which monetary policy can deviate from active in.ation stabilization and agents face uncertainty about the nature of these deviations. When observing a deviation, agents conduct Bayesian learning to infer its likely duration. Under...
