Cooperation through communication: Teams and individuals in finitely repeated Prisoners' dilemma games

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 achieve, with minimal discussion of punishment for failing to cooperate. Restoring cooperation after an early stage-game defection typically requires compensating the aggrieved agent.
