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...

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...

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:...

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...

The potential economic outcomes resulting from a flat rate of income tax have been the subject of an ongoing academic and political debate. Many observers have suggested that the introduction of a flat tax would be beneficial for a country's economy, having a positive influence on the labor...

New Zealand’s tax system is one of the most neutral and efficient in the OECD. Bases are generally broad and rates are moderate. The full imputation system for dividend payments works to reduce tax distortions for corporate financing decisions, while efficiency in corporate investment...

The tax burden in Korea is among the lowest in the OECD area, mainly reflecting that the social safety net is at an early stage of development. The low tax burden implies limited tax induced economic distortions but as expenditure pressures will mount in the future, neutrality and efficiency of...

The Mexican tax system encompasses a number of commendable features and disincentives to work, save and invest appear less severe than in most other OECD countries. However, the system also contains major deficiencies, which hampers the efficiency and equity of the system and contribute to the...

The Japanese tax system applies relatively low marginal tax rates on most economic activities which, in combination with moderate tax elasticities of the bases, indicate that the overall distortion from the tax system (the excess burden) is probably modest compared with other OECD countries....
