Alexia Gaudeul, Claudia Keser, and Stephan Müller (Games and Economic Behavior, 2021) We theoretically and experimentally study the evolution of strategies reflecting different moral judgments under indirect reciprocity. We find that stable states of cooperation are characterized by the coexistence of different morals and the presence of players who’s behaviour depends on second-order information about past interactions.
