We report experiments designed to test between Nash equilibria that are stable and unstable under learning. The “TASP” (Time Average of the Shapley Polygon) gives a precise prediction about what happens when there is divergence from equilibrium under a wide class of learning processes. We...

We use experiments to analyze what type of communication is most effective in achieving cooperation in a simple collusion game. Consistent with the existing literature on communication and collusion, even minimal communication leads to a short run increase in collusion. However, in a limited...

We report experiments designed to test the theoretical possibility, first discovered by Shapley (1964), that in some games learning fails to converge to any equilibrium, either in terms of marginal frequencies or of average play. Subjects played repeatedly in fixed pairings one of two 3 × 3...

We introduce a procedure to infer the repeated-game strategies that generate actions in experimental choice data. We apply the technique to set of experiments where human subjects play a repeated Prisoner's Dilemma. The technique suggests that two types of strategies underly the data.

La presente investigación tiene dos objetivos básicos. Primero, se utilizarán elementos de la Teoría de Juegos Evolutivos para evaluar la estabilidad de distintos tipos de preferencias en el contexto de la explotación de un recurso de propiedad común. En particular, analizaremos la...

We explore whether competitive outcomes arise in an experimental implementation of a market game, introduced by Shubik (1972). Market games obtain Pareto inferior (strict) Nash equilibria, in which some markets are closed. We find that subjects do not coordinate on autarkic Nash equilibria, but...

While there is an extensive literature on the theory of infinitely repeated games, empirical evidence on how the shadow of the future affects behavior is scarce and inconclusive. I simulate infinitely repeated prisoner's dilemma games in the lab with a random continuation rule. The experimental...
