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...

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...

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...

We build a RBC endogenous separation matching model and introduce efficiency wages along the lines of Akerlof (1982). While the standard endogenous separation matching model reveals shortcomings in explaining correlations and volatilities jointly, this approach performs reasonably well along...

In the recent New Keynesian literature a standard assumption is that the price for which an intermediate good is sold to the final good firm is equal to the marginal costs of the intermediate good firm. However, there is empirical evidence that this need not to hold. This paper introduces price...

This paper estimates whether learning-by-doing effects or cleansing effects of recessions drive the endogenous component of productivity in the United States. Using Bayesian estimation techniques we find that external and internal learning-by-doing effects dominate. We find no evidence for...

This paper analysis two types of firing costs in a New Keynesian model with search and matching frictions and purely endogenous separations. We further distinguish between the effects resulting from respecting and non-respecting the bonding critique. We find that the two types of firing costs...

Empirical evidence indicates that lay-off costs consist of two elements, namely firing costs and severance payments. This paper investigates business cycle and steady state effects of firing costs and severance payments and discusses the differences. We find that severance payments imply a lower...
