This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma rule of...

Deutschland wird im europäischen Vergleich häufig ein überdurchschnittlich progressives Steuersystem attestiert. Die einzigartige, mehrstufige Progressionsformel der Einkommensteuer trägt ohne Zweifel zu dieser Sichtweise bei. Um ein umfassendes Bild der Progressivität eines Gesamtsystems...

We demonstrate that a rank-preserving transfer from a richer individual to a poorer individual can exacerbate income inequality (when inequality is measured by the Gini coefficient). This happens when individuals' preferences depend negatively not only on work time (effort) but also on low...

Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare...

Recent discussions about rising inequality in industrialized countries have triggered calls for more government intervention and redistribution. Due to obvious behavioral effects caused by redistribution, it is however not clear whether redistributional policies are indeed able to combat...

This paper suggests multidimensional affluence measures for the top of the distribution. In contrast to commonly used top income shares, they allow the analysis of the extent, intensity and breadth of affluence in several dimensions within a common framework. We illustrate this by analyzing the...
