  Online Price Dispersion: A Game Theoretic Perspective and Empirical Evidence

  Abstract:The existence and persistence of price dispersion for identical products in online markets have been well documented in the literature. Possible explanations of this price dispersion, derived mainly using hedonic price models, have seen only modest success. In this paper, we propose a competitive model, based on online retailers’ differentiation, mainly in service provided and recognition enjoyed, to explain price dispersion. Our exploratory empirical analyses, using cross-sectional data, demonstrate that the competitive model provides a better explanation of the association between prices and online retailer’s service and recognition levels. In addition, our competitive model is able to explain observations that are seemingly inconsistent with the hedonic model, such as the negative association between service and price. This paper contributes to the literature on price dispersion by offering a differentiation model that provides good fit with data, and by proposing a theory that explains previous counter-intuitive observations of prices. Our model also helps an e-tailer to choose a desirable position in the competitive market.
