Identifying the strategies that are played is critical to understanding behavior in repeated games. This process is difficult because only choices (not strategies) are observable. Recently, a debate has emerged regarding whether subjects play mixed strategies in the indefinitely repeated...

We study the evolution of cooperation in the indefinitely repeated prisoner's dilemma when it is costly for players to adjust their strategy. Our experimental interface allows subjects to design a comprehensive strategy that then selects actions for them in every period. We conduct lab...

We propose a new approach for running lab experiments on indefinitely repeated games with high continuation probability. This approach has two main advantages. First, it allows us to run multiple long repeated games per session. Second, it allows us to incorporate the strategy method with...
