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...
