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 fictitious play like learning processes....

I propose a novel experimental approach to the study of learning in repeated games, complementing the analysis of players' actual choices with data on the information acquisition process they follow. The game played is a repeated Cournot oligopoly, with limited information. The econometrics...

The paper presents the concept of an imitation equilibrium and explores it in the context of some simple oligopoly models. The concept applies to normal form games enriched by a reference structure specifying a reference group for every player. The reference group is a set of other players, whom...
