In each of six treatments that vary the cooperation premium and the informational basis for reputation …, that with a high cooperation premium and good information, investment in reputation grows across sets of finitely …

interaction impacts cooperation within groups and surplus distribution. We developed and tested experimentally a Surplus … Allocation Game where cooperation of four agents is needed to produce surplus, but only two have the power to allocate it among … distributors and receivers. While behavior at the group level is diverse for surplus allocation and amount of cooperation …

. For this purpose, we develop an infinitely repeated rent-seeking model with two groups where within-group cooperation is … then characterize the conditions under which cooperation among fellow members within each group can be achieved as a … stationary subgame perfect equilibrium. The main conclusion is that the larger group has more chances to maintain cooperation …

of a Prisoner's 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's 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 …
