Hours per capita measures based on the private sector as usually included in the set of observables for estimating macroeconomic models are affected by low-frequent demographic trends and sectoral shifts that cannot be explained by standard models. Further, model-based output gap estimates are...

Endogenous separation matching models have the shortcoming that they are barely able to replicate the Beveridge curve (i.e. the negative correlation between unemployment and vacancies) and business cycle statistics jointly. This paper builds upon the sectoral shock literature and combines its...

This paper analyzes the costs of housing crises in terms of GDP growth and the economic conditions under which crises are particularly costly. Housing crises are often followed by recessions that are longer than other recessions. According to empirical estimates, a housing crisis reduces the GDP...

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...

This analysis provides evidence for the costs housing crises induce in terms of GDP growth and under what circumstances these crises are particularly costly. Housing crises are often followed by recessions that are longer and deeper than other recessions. According to empirical estimates, a...

I build a dynamic stochastic general equilibrium model with search and matching frictions in the labor market and analyze the optimal monetary policy response to an outward shift in the Beveridge curve. The results cover several cases depending on the reason for the shift. If the shift is due to...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether the rule based component (i.e., the existence of the institution short-time work) and the discretionary component...

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...

Sowohl die deutschen Exporte als auch die Importe von Waren und Dienstleistungen weisen im Zeitraum 1974?1999 bezüglich der zugrunde liegenden Aktivitätsvariablen eine langfristige Elastizität von jeweils rund 1,5 auf. Die Langfristelastizität in Bezug auf den realen Außenwert der D-Mark...
