Different stochastic simulation methods are used in order to check the robustness of the outcome of policy simulations with a macroeconometric model. A macroeconometric disequilibriummodel of the West German economy is used to analyze a reform proposal for the tax system. The model was estimated...

In diesem Beitrag wird auf der Basis von Paneldaten für die westdeutschen Bundesländer untersucht, ob und in welchem Maße der demographische Wandel sowie die unterschiedlichen politischen Parteienkonstellationen die Hochschulausgaben auf Länderebene beeinflussen. Wir finden empirische...

This paper studies the relationship between wages and the degree of firm heterogeneity in a given industry under different wage setting structures. To derive testable hypotheses, we set up a theoretical model that analyses the sensitivity of wages to the variability in productivity conditions in...

Using a large linked employer-employee data set, this paper studies the extent to which employers insure workers against transitory and permanent firm-level shocks. Particular emphasis is given to the question of whether the amount of wage insurance depends on the nature of industrial relations....

We analyze the impact of changing employment patterns and pension reforms on the future level of public pensions across birth cohorts in Germany. The analysis is based on a rich dataset that combines household survey data from the German Socio-Economic Panel Study (SOEP) and process-produced...

This paper provides new estimates of a timevarying NAIRU for Germany taking account of the structural break caused by German unification based on the Kalman Filter and on a partially linear model as two alternatives. Estimating a standard Phillips curve, the sum of coefficients associated with...

Ziel dieses Beitrags ist die Quantifizierung der mit der Einführung des Arbeitslosengeldes II verbundenen Arbeitsangebots- und Beschäftigungseffekte. Zusätzlich wird ein Reformszenario simuliert, welches die Anreizstruktur im Niedriglohnbereich verbessern soll. Methodisch wird ein...

Using a linked employer-employee data set, this paper analyses the relationship between firm profitability and wages. Particular emphasis is given to the question of whether the sensitivity of wages to firm-specific rents varies with collective bargaining coverage. To address this issue, we...
