Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use and the reaction on the introduction of a norm enforcement mechansism have been documented in cross-cultural studies, recently. We present data which prove that stark...

In contrast to previous studies on cross-group comparisons of conditional cooperation, this study keeps cross- and within-country dimensions constant. The results reveal significantly different cooperation behavior between social groups in the same location.<p>

This paper derives Pareto efficient policy rules for the provision of national as well as global public goods in a two-country world, where each individual cares about relative consumption within as well as between countries. Furthermore, we compare these policy rules with those that follow from...

Previous studies on public policy under relative consumption concerns have ignored the role of leisure comparisons. This paper considers a two-type optimal nonlinear income tax model where people care both about their relative consumption and their relative leisure. Increased consumption...

This paper concerns optimal income taxation and provision of a state-variable public good under asymmetric information in a two-type overlapping generations model, where people care about their relative consumption. Each individual may compare his/her own current consumption with his/her own...

Almost all previous studies on public policy under relative consumption concerns have ignored the role of leisure for status comparisons. Inspired by Veblen (1899), this paper considers a two-type optimal income tax model, where people care about their relative consumption, and where the...

We develop a theoretical model in which each individual is, in some ultimate sense, motivated by purely egoistic satisfaction derived from the goods accruing to him, but there is an implicit social contract such that each performs duties for the others in a way that enhances the satisfaction of...

This text (Keser) is a survey and a discussion of experimental studies on cooperation in public goods experiments. It is followed by a comment (Montmarquette) suggesting some economic applications from these experimental studies. Ce texte (Keser) présente une revue et une discussion des écrits...

We show that the famous neutrality result in the theory of public good contributions (Warr, Kemp, Bergstrom, Blume and Varian) depends crucially on the assumption that agents do not take into account the effect of their public good contribution decisions on the relative price of the private...

We show that peer sanctioning increases cooperation in public goods experiments more in unequally endowed groups than in equally endowed groups. Punishment results in a redistribution of wealth from high to low endowment players within groups. <p>
