We present the operationalized Toll Index, which is a new type of early indicator for the German business cycle. We present the basic idea and document the power of the indicator for the purpose of nowcasting. The data will be regularly available at the IDSC, the data bank center of IZA and will...

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...

We implement capital in an endogenous separations New Keynesian matching model. In contrast to the vintage capital theory, we suggest a more general approach, such that workers have unrestricted access to a proportional share of the capital stock. We find that the introduction of capital...

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...

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 papers analyzes the role of the extensive vis-à-vis the intensive margin of labor adjustment in Germany and the United States. The contribution is twofold. First, we provide an update of older U.S. studies and confirm the view that the extensive margin (i.e., the adjustment in the number...

The internet has become an important data source for the Social Sciences because these data are available without lags, can be regarded as involuntary surveys and hence have no observer effect, can be geo-labeled, are available for countries across the globe and can be viewed in continuous time...

This paper documents a puzzling fact, namely that there is a significant negative relation between employment protection legislation and the usage of the intensive margin of labor market adjustments. We then make use of a Real Business Cycle model and introduce search and matching frictions as...

Nowcasting has been a challenge in the recent economic crisis. We introduce the Toll Index, a new monthly indicator for business cycle forecasting and demonstrate its relevance using German data. The index measures the monthly transportation activity performed by heavy transport vehicles across...
