Jinyeong Sohn, IAER Assistant Professor, had his paper accepted for publication in Games and Economic Behavior on October 5th, 2022. Entitled "Reciprocity with Uncertainty about Others", the paper was co-authored with Wenhao WU, Assistant Professor at ShanghaiTech University.
The authors introduce the uncertainty of psychological motivation into a reciprocity model and explore its implications on behavior. More precisely, they assume that reciprocity parameters are subject to incomplete information and extend the Sequential Reciprocity Equilibrium concept in extensive-form games (Dufwenberg, 2004) to a broader class of incomplete information games. They use this general framework to study many well-known games and find that uncertainty could either mitigate or strengthen players' reciprocal behavior. They investigate how uncertainty changes the equilibrium predictions of the standard reciprocity model and compare two setups in which the psychological motivations are known and unknown among the players, respectively. In particular, the authors find that, in the prisoners' dilemma, players are more likely to cooperate with each other when they have information about the reciprocal motivations of their opponents, given that the benefits of defection are modest.
