This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...

Der Finanzwissenschaftliche Ausschuß des Vereins für Socialpolitik hat 1997 auf der Rostocker Tagung begonnen, sich mit Problemen der Besteuerung zu befassen (vgl. den von A. Oberhauser herausgegebenen Band 'Probleme der Besteuerung I', Berlin 1998). Diese Diskussion wurde 1998 auf der...

Das Bundesverfassungsgericht erklärte in zwei Entscheidungen, 1990 den Kinderfreibetrag und 1992 den Grundfreibetrag des deutschen Einkommensteuergesetzes für zu niedrig und damit im Widerspruch zum Grundgesetz. In der vorliegenden Arbeit werden die international üblichen tarifpolitischen...

This paper studies optimal linear income taxation and redistributive social insurance when the former has the traditional labor distortion and the latter generates both ex ante and ex post moral hazard. Private insurance is available and individuals differ in labor productivity and in loss...
