摘要：We demonstrate how to estimate a model of oligopoly pricing when products are multi-dimensionally differentiated. We provide an empirical counterpart to recent theoretical work on product differentiation. Using specifications informed by economic theory, we estimate price-cost margins for products differentiated in many dimensions.
