Capacity Choices and Price Competition in Experimental Markets



We report on experimental duopoly markets with heterogeneous goods. In these markets, sellers first choose capacities and then prices. While capacities remain fixed for either five or ten periods, prices have to be chosen in every period. The experiments starts with two sets of exogenously predetermined capacities. Independently of the distribution of capacities is, a unique pure-strategy in prices is subgame perfect. In equilibrium, capacities should correspond to the Cournot prediction. Given capacities, price-setting behavior is in general consistent with the theory. Average capacities converge above the Cournot level. Capacities converge at the industry level but are somewhat dispersed. Sellers rarely manage to cooperate. Copyright Kluwer Academic Publishers 2003
