An attention-grabbing paper by Cooper and Kegel (2023) in AEJ: Microeconomics finds that utilizing groups (fairly then people) within the prisoner’s dilemma recreation is extra prone to lead to selecting to cooperate than could be the case if people enjoying one another.

We examine habits of two particular person groups with people in indefinitely repeated prisoner dilemma video games with good monitoring. Staff discussions are used to know the rationale underlying these selections and the way these selections come about. There are three fundamental findings: (i) Groups realized to cooperate sooner than people, and cooperation was extra secure for groups. (ii) Methods recognized from group dialogues differ from these recognized by the Technique Frequency Estimation Technique. This displays the improvisational nature of groups’ choice making. (iii) Growing cooperation was primarily pushed by groups unilaterally cooperating within the hope of inducing their opponent to cooperate.
