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 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...

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...

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:...

How do different components of the tax and transfer systems affect disposable income inequality? This paper explores the redistributive effects of different tax benefit instruments in the enlarged EU based on two approaches. Inequality analysis based on the standard approach suggests that...

This paper investigates to what extent the tax and transfer systems in Europe protect households at different income levels against losses in current income caused by economic downturns like the present financial crisis. We use a multi country micro simulation model to analyse how shocks on...
