Exogenously imposed infinite repetition is known to mitigate people's uncooperative behaviors in dilemma situations with partner matching through personal enforcement. One as yet unanswered question is whether people collectively choose to interact with each other under the partner matching...

Subjects who played a payoff-maximising strategy against a computer algorithm ("sophisticates") are more cooperative in a finitely repeated Prisoner's Dilemma than subjects who did not play a payoff-maximising strategy ("naifs"). The difference in cooperation rates increases as the subjects gain...

In repeated games, reciprocity helps to sustain group cooperation. Using the Markovian strategy as a touchstone, we explore the evolution of cooperation in the infinitely repeated and noisy n-person Prisoner's Dilemma. With some modified game settings, we show that a class of cooperative...

Intelligence affects social outcomes of groups. A systematic study of the link is provided in an experiment where two groups of subjects with different levels of intelligence, but otherwise similar, play a repeated prisoner's dilemma. The initial cooperation rates are similar, it increases in...

We investigate in a laboratory setting whether revealing information on intelligence affects behavior in games with repeated interactions. In our experimental design we communicate information on the cognitive ability of both players. We use three stage games: Prisoners' Dilemma (PD) and two...

We investigate in a laboratory setting whether revealing information on the intelligence of both players affects behavior in repeated games. We study the Prisoners' Dilemma (PD) and Battle of Sexes (BoS) as they cover a large set of the interesting scenarios generated by repeated games of two...

Identifying mechanisms able to sustain costly cooperation among self-interested agents is a central problem across social and biological sciences. One possible solution is peer punishment: when agents have an opportunity to sanction defectors, classical behavioral experiments suggest that...

A large literature in behavioral economics has emphasized in the last decades the role of individual differences in social preferences (such as trust and altruism) and in influencing behavior in strategic environments. Here we emphasize the role of attention and working memory, and show that...

Algorithms play an increasingly important role in economic situations. These situations are often strategic, where the artificial intelligence may or may not be cooperative. We study the deter-minants and forms of algorithmic cooperation in the infinitely repeated prisoner’s dilemma. We run a...
