Repeated Game Strategies in Local and Group Prisoner`s Dilemma
We investigate and compare different approaches to derive strategies from observed data in spatial and spaceless prisoners' dilemmas experiments. We start with a model where players choose a fixed action that remains constant for all repetitions of a stage game. As an extension we then allow players to choose simple repeated game strategies that, however, remain fixed over the course of the game. We then discuss a method how to identify changing repeated game strategies. This method is used to study a simple reinforcement model. We find that in a spatial structure reinforcement plays a more important role than in a spaceless structure.
