Two duopoly market structures are experimentally constructed. Payoff tables describe basic conditions in an X market and a Y market. In one market structure two rivals choose X quantities and a different set of rivals choose Y quantities. These markets develop equilibria independently. A second...

We analyze learning in a two-person simultaneous choice repeated game. Agents form beliefs about their rival's strategies, which they revise as the game progresses. We test this model using data from a series of experiments. We obtain data on subjects' expectations by asking them to predict...

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....
