In der Debatte über die Neuordnung der Einkommensbesteuerung in Deutschland gilt die Steuervereinfachung als eines der zentralen Reformziele. Das liegt nicht nur daran, dass das bestehende komplizierte System den Steuerpflichtigen und den Finanzbehörden hohe Verwaltungskosten aufbürdet. Die...

In der Debatte über eine Reform des deutschen Einkommensteuersystems wird immer wieder die Einführung einer Flat Rate Tax gefordert. Üblicherweise bestehen solche Vorschläge aus den Elementen Verbreiterung der Bemessungsgrundlage, Erhöhung des Grundfreibetrags und Einführung eines (relativ...

This paper applies multidimensional affluence measures to a new dataset on income and wealth in 15 Eurozone countries. We start our analysis by examining the income and wealth distributions separately for each country, and extend it to a multidimensional setting by considering the joint...

Rising income inequalities are widely debated in public and academic discourse. In this paper, we contribute to this debate by proposing a new family of measures of unfair inequality. To do so, we acknowledge that inequality is not bad per se, but that its underlying sources need to be taken...

The success of the flat rate tax in Eastern Europe suggests that this concept could also be a model for the welfare states of Western Europe. The present paper uses a simulation model to analyse the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of...

The flat income tax has become increasingly popular recently, yet its implementation is limited to Eastern Europe. We analyse the distributional and efficiency effects of flat tax scenarios for Western European countries. Our simulations show that flat tax rates required to attain revenue...

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich persons' income and therefore allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures to...

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...

This paper deals with concepts of multidimensional poverty measurement and applies them to Germany. Three concepts of poverty are examined and included into one multidimensional approach: economic well being, capability and social exclusion. The empirical application relies on indices introduced...

We assess the effects of U.S. tax policy reforms on inequality by applying a new decomposition method that allows us to disentangle mechanical effects due to changes in pre-tax incomes from direct effects of policy reforms. While tax reforms implemented under Democrat administrations, in...
