标题：ESTIMATING MARKET POWER AND PRICING CONDUCT FOR PRIVATE-LABEL AND NATIONAL BRANDS IN A PRODUCT-DIFFERENTIATED OLIGOPOLY: THE CASE OF A FROZEN VEGETABLE MARKET
摘要：This paper develops two brand-level demand models, where prices are treated as endogenous, to estimate unilateral market power in a representative product-differentiated oligopolistic food market. The results are estimated using point-of-purchase scanner data and are used to quantify the impact of a private-label brand on the economic performance of national brands. Specifically, our study calculates demand parameter estimates and returns to retailer vertical coordination for the frozen vegetable marketthe third largest private-label food and beverage category in the United States, after ice cream and carbonated beverages. Consistent with broader industry trends, empirical evidence suggests that the private-label brand maintained a slight competitive advantage over Birds Eye and Green Giant.
