Die aktuelle energiepolitische Debatte hat die längerfristigen Perspektiven einer nachhaltigen Energieversorgung allzu sehr aus dem Blick verloren. Vor allem die Potentiale der Kernfusion werden in der öffentlichen Diskussion kaum wahrgenommen. Dabei würden sich viele Probleme, die mit dem...

In state-of-the-art macroeconomic and labor market models shocks are assumed to be homoscedastic. However, we show that this assumption is much too restrictive. We estimate the conditional variance-covariance matrix using a VAR-DCC model and discuss the time-varying risk contained in a large set...

In this paper, we analyze the consequences of delays and cost overruns typically associated with the provision of public infrastructure in the context of a growing economy. Our results indicate that uncertainty about the arrival of public capital can more than offset its positive spillovers for...

This paper introduces productivity dependent firing costs in an endogenous separation New Keynesian model. By strictly respecting the bonding critique, we show that firing costs tend to increase the performance of the model along the labor market dimension but fail along the persistence...

This paper provides a survey of the recent literature about firing costs and discusses the transmission channels of firing costs in a partial equilibrium context. In addition, we expand our analysis two types of firing costs in a New Keynesian model with purely endogenous separations. We further...

Shocks driving the business cycle have different effects on low-skilled and high-skilled workers. This paper studies the effects of temporary and permanent sector-specific shocks in a New Keynesian matching model. We show that temporary sector-specific shocks have reallaction and aggregate...

This paper investigates the role of staggered wages and sticky prices in explaining stylized labor market facts. We build on a partial equilibrium search and matching model and expand the model to a general equilibrium model with sticky prices and/or staggered wages. We show that the core model...
