DP7315 A Dynamic Model of Price Discrimination and Inventory Management at the Fulton Fish Market
We estimate a dynamic profit-maximization model of a fish wholesaler who can observe consumer characteristics, set individual prices, and thus engage in third-degree price discrimination. Simulated prices and quantities from the model exhibit the key features observed in a set of high quality transaction-level data on fish sales collected at the Fulton fish market. The model?s predictions are then compared to the case in which the dealer must post a single price to all customers. We find the cost to the dealer of posting a uniform price to be extremely small.
