Using two data sets derived from German administrative data, including a linkedemployer-employee data set, we investigate the cyclicality of worker and job flows.The analysis stresses the importance of two-sided labour market heterogeneity inthis context, taking into account both observed and...

In this paper, we provide a comprehensive overview of labour market dynamics in Western Ger- many by looking at gross worker flows. To do so, we use a subsample of the registry data collected by the German social security system, the IAB employment sample, for the time period 1975-2001. The...

We analyse the effect of skill mismatch in a search model of equilibrium unemployment with risk-neutral agents, endogenous job destruction, and two-sided ex-ante heterogeneity. First, we examine the interaction of labour market institutions and skill mismatch. We find that skill mismatch changes...

The secular rise of European unemployment since the 1960s is hard to explain without reference to structural change. This is especially true in Germany, where industrial employment has declined by more than 30% and service sector employment has more than doubled over the past three decades....

Using an administrative data set containing daily information on individual workers' employment histories, we investigate how workers' labour market transitions are affected by international outsourcing. In order to do so, we estimate hazard rate models for match separations, as well as for...

Using two data sets derived from German administrative data, including a linked employer-employee data set, we investigate the cyclicality of worker and job flows. The analysis stresses the importance of two-sided labour market heterogeneity in this context, taking into account both observed and...

This paper explores implications of nominal rigidity characterized by a non-constanthazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazardfunction and parameterize it with the Weibull duration model. The resulting Phillips curveinvolves lagged inflation and lagged...

In semiparametric models it is a common approach to under-smooth the nonparametric functions inorder that estimators of the finite dimensional parameters can achieve root-n consistency. The requirementof under-smoothing may result as we show from inefficient estimation methods or technical...

This paper studies how dierent unionisation structures aect rm productivity, rmperformance, and consumer welfare in a monopolistic competition model with heterogeneousrms and free entry. While centralised bargaining induces tougher selection among hetero-geneous producers and thus increases...

In this paper we develop several regression algorithms for solvinggeneral stochastic optimal control problems via Monte Carlo. Thistype of algorithms is particularly useful for problems with a highdimensionalstate space and complex dependence structure of the underlyingMarkov process with...
