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 …

Evolution of cooperation by reciprocity has been studied using two-player and n-player repeated prisoner’s dilemma … cooperation when less generous, and better at maintaining a long-term cooperation in the presence of rare defectors when more …

The state-of-mind inference requires Bayesian belief calculations, which is computationally intensive. We therefore … of their opponent's behavior. These commitment-like decision rules can enhance or reduce cooperation depending on the …

We use experimental methods to investigate whether pledges of commitment can improve cooperation in endogenously … findings show that pledges of commitment alone can increase cooperation and welfare in committed partnerships. The introduction … partnerships fall solely on the individual choosing to break up, pledges of commitment fail to improve cooperation and welfare. …

Reciprocal cooperation can be studied in the Centipede game, in which two players alternate in choosing between a … investigated cooperation in four Centipede games differing in their payoffs at the game's end (positive versus zero) and payoff … high payoff inequality were found to reduce cooperation significantly. Contrary to previous predictions, combining these …

Conversely, when switching from small to large, cooperation … probabilities. These asymmetries suggest a bias in favor of cooperation. Finally, we examine the link between altruism and RPD play …

However, emotions can also … obstruct cooperation if they make the players unwilling to punish each other, or if the players become hostile when punished. …
