Social and political inequality among individuals is a common driving force behind the breakdown in cooperation. In … this paper, we theoretically and experimentally study cooperation among individuals faced with a sequence of collective …-action problems in which the benefits to cooperation are divided according to political power that is obtained through a contest. We …

of a Prisoner' Dilemma game. When time preferences are heterogeneous and bounded away from one, how "much" cooperation … can be achieved by an ongoing group? How does group cooperation vary with the group' size and structure? For an arbitrary … distribution of discount factors, we characterize the maximal average co-operation (MAC) likelihood of this game. The MAC …

In this paper we show experimentally that conditional cooperation, a phenomenon described in the private provision of … determines if they overcome a rival group. This environment allows us to identify new determinants of conditional cooperation. We … observe conditional cooperation in successful groups and in groups where members contribute more than rivals (even if they …
