Die Steuerbelastung von Unternehmens- und Vermögenseinkommen hat sich im Vergleich zur Belastung der Arbeitnehmerentgelte seit 1980 mehr als halbiert. Worauf ist die sinkende Steuerbelastung von Unternehmens- und Vermögenseinkommen zurückzuführen? Wie sollten die Unternehmen angesichts der...

Competitive pressure on some capital income tax rates reinforces a generic quadrilemma or a four-way tradeoff in domestic income taxation. To maintain competitiveness, governments have to cut some tax rates on capital income down to international standards. If these cuts lead to a de-alignment...

This note derives a model of the wage curve, closely following Phelps (1994) and Campbell and Orszag (1998). Phelps discusses a variety of theoretical bases for a wae curve, the two major competing types being bargaining models and efficiency wage models, though Phelps prefers the term...

Identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates. Marginal tax rates vary with income, but income surely affects portfolio choice directly. In systems of individual taxation - like Canada's - couples with the same...

This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

We characterize optimal redistributive taxation when individuals are heterogeneous in their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are endogenous. Average tax rates are increasing...

This paper presents the case for tax progressivity based on recent results in optimal tax theory. We consider the optimal progressivity of earnings taxation and whether capital income should be taxed. We critically discuss the academic research on these topics and when and how the results can be...
