This paper studies monitoring and punishment behavior by second and third parties in a cooperation experiment with endogenous information structures: Players are uninformed whether the target player cooperated or defected at the cooperation stage, but can decide to resolve the information...

We experimentally test the social motives behind individual participation in intergroup conflict by manipulating the framing and symmetry of conflict. We find that behavior in conflict depends on whether one is harmed by actions perpetrated by the out-group, but not on one’s own influence on...

This paper investigates how the possibility of affecting group composition combined with the possibility of repeated interaction impacts cooperation within groups and surplus distribution. We developed and tested experimentally a Surplus Allocation Game where cooperation of four agents is needed...

We introduce a novel approach to studying behavior in repeated games - one that is based on the psychology of play. Our approach is based on the following six "aspects" of a player's behavior: round-1 cooperation, lenience, forgiveness, loyalty, leadership, and following. Using a laboratory...

We use experimental data from the “vote with the wallet” multiplayer prisoner's dilemma to investigate with a finite mixture approach the effect of a responsible purchase on players' satisfaction. We find clear-cut evidence of heterogeneity of preferences with two groups of players that...

We study the effect of network formation on cooperation in the finitely repeated prisoner’s dilemma based on the game-theoretical model approach. We suggest the model explaining the effect of endogenous network formation on cooperation. We find a subgame perfect strongly pairwise-Nash...

In finitely repeated prisoner dilemma games, two-person teams start out with significantly less cooperation than individuals, consistent with results reported in the social psychology literature. However, safety concerns quickly give way to teams cooperating significantly more than individuals....

Punishment has been shown to be an effective reinforcement mechanism. Intentional or not, punishment will likely generate spillover effects that extend beyond one’s immediate decision environment, and these spillovers are not as well understood. We seek to understand these secondary spillover...

For both two person teams and individuals unrestricted communication between opponents in a finitely repeated prisoner dilemma game results in stage-one cooperation rates of between 95-100%. Content analysis of between opponent communication focuses on the increased earnings cooperation can...

Often in cooperative situations, many aspects of the decision-making environment are uncertain. We investigate how cooperation is shaped by the way information about risk is presented (from description or from experience) and by differences in risky environments. Drawing on research from risky...
