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>

We study pure redistribution as a device to increase cooperation and efficiency in the provision of public goods. Experimental subjects play a two-stage game. The first stage is the standard linear public goods game. In the second stage, subjects can redistribute payoffs among other subjects in...

In this paper, we study the effectiveness of intergroup competition in promoting cooperative behavior. We focus on intergroup competition that is non-rival in the sense that everyone can be a winner. This type of competition does not give groups an incentive to outcompete others. However, in...

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...

The sanctioning of norm-violating behavior by an effective formal authority is an efficient solution for social dilemmas. It is in the self-interest of voters and is often favorably contrasted with letting citizens take punishment into their own hands. Allowing informal sanctions, by contrast,...

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>

Since the analysis of a self-enforcing agreement by Barrett (1994) it has been clear that the ratio between the slopes of the marginal cost and marginal benefit functions is conclusive for stability of self-enforcing agreements. For example Finus and Rundshagen (1998) stated: 'it turns out that...

Kaplow (1996) and others argue forcefully in favor of using the standard cost-benefit test alone, without any distributional concern, given “standard simplifying assumptions.” This paper, on the contrary, demonstrates that distributional weights, equal to the social marginal utility of...

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...
