Abstract

Using data obtained from experiments reported in García-Gallego (1998) and García- Gallego and Georgantzís (2001), we estimate a simple model of adaptive behavior which could describe pricing in a market whose demand conditions are unknown to the firms. Divergence between the limit of observed prices over time and theoretical predictions concerning multiproduct firms could be partially explained as a result of learning limitations associated with multiple task-oriented problem solving. However, optimal multiproduct pricing requires that subjects use two different kinds of rules: one concerning responses to prices charged by other players and another concerning pricing of own products. Even in a simple environment like the one studied here, subjects seem to be far more successful in learning a number than learning a rule.
