We study the evolutionary robustness of strategies in in infinitely repeated prisoners' dilemma games in which players make mistakes with a small probability and are patient. The evolutionary process we consider is given by the replicator dynamics. We show that there are strategies with a...

We use a novel experimental design to identify the subjects' strategies in an infinitely repeated prisoners' dilemma experiment. We ask subjects to design strategies that will play in their place. We find that eliciting strategies has negligible effects on their behavior, supporting the validity...

The use of moral appeals to affect the behavior of others is pervasive (from the pulpit to ethics classes) but little is known about the effects of moral suasion on behavior. In a series of experiments we study whether moral suasion affects behavior in voluntary contribution games and the...
