Abstract This paper studies theoretically and experimentally how success in prior interaction affects cooperation in the one-shot Inter-group Prisoner's Dilemma (IPD). We develop a model of the IPD that incorporates group-contingent social preferences and bounded rationality to derive conditions under which an increase in pro-social concerns for an out-group will increase cooperation. We then report an experiment that shows the cooperation rate increases from 8 percent in a baseline one-shot IPD...

We study experimentally the indefinitely repeated noisy prisoner’s dilemma, in which random events can change an intended action to its opposite. We investigate whether groups choose Always Defect less and use lenient or forgiving strategies more than individuals,and how decision-makers experiment with different strategies by letting them choose from an extensive list of repeated game strategies. We find that groups use forgiving and tit-for-tat strategies more than individuals. Always Defect, h...

Appointing a successor (the “prince”) allows the ruler (the “king”) to alter the structures of conflicts that take place between him and his potential challengers, as well as the structures of conflicts that take place among his potential challengers. Motivated by historical examples and using an infinite horizon rulership competition game, we show that while an appointed prince constitutes a powerful and dangerous threat to the incumbent ruler (the elevated threat effect), the appointed prince ...

This paper presents a laboratory experiment to investigate how social motivations and free-form communication (Rich Communication) can facilitate coordinated resistance against divide-and-conquer transgressions. In our experiment, a leader first decides whether to extract surplus from a victim and shares it with a beneficiary. We find that the successful joint resistance rate increases almost four-fold (from 15 to 58%) when moving from more restrictive communication treatments to Rich Communicat...

This paper reports an experiment to evaluate the effectiveness of repeated interactions in deterring leaders’ from using divide-and-conquer strategies to extract surplus from their subordinates, when every decision-maker involved is a group instead of an individual. We find that both the resistance rate by subordinates and the divide-and-conquer transgression rate by leaders are the same in the group and individual repeated coordinated resistance games. Similar to the individual game, adding com...

Successful deterrence of leader expropriation is important for economic development. This article studies experimentally how repeated interactions and communication can help deter leaders from extracting surplus from their subordinates. We show that repetition alone is far from sufficient in deterring leader expropriation. Communication between subordinates is critical for increasing coordinated resistance even when the information communicated is highly restrictive. Adding communication reduces...

Many interactions between groups resemble an inter-group prisoner’s dilemma (IPD), and the ability or inability for groups to cooperate in such environments is crucial for organizational performance and community welfare. This paper studies theoretically and experimentally how prior social interactions that affect individuals’ pro-social concerns for their out-group members may affect cooperation in a one-shot IPD. The model incorporates group-contingent social preferences, the importance of piv...

History-dependent strategies are often used to support cooperation in repeated game models. Using the indefinitely repeated common-pool resource assignment game and a perfect stranger experimental design, this paper reports novel evidence that players who have successfully used an efficiency-enhancing turn-taking strategy will teach other players in subsequent supergames to adopt this strategy. We find that subjects engage in turn taking frequently in both the Low Conflict and the High Conflict ...

Turn taking is observed in many field and laboratory settings captured by various widely studied 2 ×2 games. This article develops a repeated game model that allows us to systematically investigate turn-taking behavior in many 2 × 2 games, including the battle of the sexes, the game of chicken, the game of common-pool- resources assignment, and a particular version of the prisoners' dilemma. We consider the"turntakingwithindependent randomizations"(TTIR)strategythatachievesthree objectives:(a)he...

This paper presents a laboratory experiment to investigate how computer-mediated free form communication (Rich Communication) can facilitate coordinated resistance against leader misbehavior. In the Coordinated Resistance game, a leader first decides whether to practice divide-and-conquer, in which he extracts surplus from a victim and shares it with a beneficiary to gain the latter’s support. Using content analysis, we provide direct evidence that the beneficiaries and the victims of divide-and...
