Diese Dokumentation beschreibt das integrierte Steuer-Transfer-Mikrosimulations- und CGE-Modell FiFoSiM des Finanzwissenschaftlichen Forschungsinstituts an der Universität zu Köln (FiFo). FiFoSiM unterscheidet sich von den bisherigen Steuer- und Transfersimulationsmodellen auf zweierlei Weise...

Deutschland wird häufig ein im europäischen Vergleich überdurchschnittliches Abgabenniveau bescheinigt. Da dies als eine der Hauptursachen für vergleichsweise schwaches Wachstum und hohe Arbeitslosigkeit gilt, werden in der wirtschaftspolitischen Debatte vermehrt Reformen des progressiven...

When comparing tax benefit systems across Europe, Germany is usually regarded as a country with a high level of taxes and contributions which is often seen as a main challenge for the economic performance of the welfare state in terms of growth and unemployment. Especially the progressive...

This paper describes the ifo Tax and Transfer Behavioral Microsimulation Model (ifoMSM-TTL), a policy microsimulation model for Germany. The model uses household microdata from the German Socio-Economic Panel and firm data from the German Linked Employer-Employee Dataset. This microsimulation...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

We present a conceptual framework for the analysis of politically feasible tax reforms. First, we prove a median voter theorem for monotonic reforms of non-linear tax systems. This yields a characterization of reforms that are preferred by a majority of individuals over the status quo and hence...

This paper describes IZAΨMOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZAΨMOD consists of three components:...

This paper describes IZA[psi]MOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZA[psi]MOD consists of three...

This documentation describes FiFoSiM, the integrated tax benefit microsimulation and CGE model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural...
