Estimating Markups and Market Conduct with Multidimensional Product Attributes
展示了当产品在多维度上存在差异时，如何估计寡头定价模型，为产品差异化的理论研究提供了实证方法，并估计了多维度差异化产品的价格成本加成。
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.
