This paper characterises the domestic tax systems which yield Pareto-efficient outcomes for a two-country world economy in which each country uses distortionary taxes. Such outcomes are compared with the Nash equilibria of the world economy when each country uses its domestic tax system to...

Workfare proposals concentrate on the work incentives for welfare recipients, thus focusing on the labor supply side. This paper analyzes the effects workfare has on labor demand when the labor market is unionized. As workfare reduces the number of recipients of public financial assistance, a...

According to the existing literature, capital taxes should not be imposed in the presence of optimal profit taxation in either unionised or competitive labour markets. We show that this conclusion does not hold for an economy with both competitive and unionised sectors, where the competitive...

Die Veröffentlichung des 3. Armuts- und Reichtumsberichts der Bundesregierung hat in der Öffentlichkeit Betroffenheit ausgelöst. Wie wird Armut gemessen und wie sollte sie bekämpft werden?

This paper employs social identity and self-categorization theories as a useful heuristic framework through which to learn more about the nature of the misery experienced by the unemployed; in economic terms, the individual cost of unemployment. Utilizing this framework, the paper provides...
