Quality-based Price Discrimination: Evidence from Internet Retailers’ Shipping Options

This paper tests various implications of quality-based price discrimination theory in the context of internet book retailers’ shipping menus. Many internet retailers create quality variants of a homogeneous good by bundling it with several shipping options that differ by delivery time. This practice can allow retailers to extract further surplus from consumers through quality-based price discrimination. We find that the design of shipping menus offered by large retailers is consistent with main implications of quality-based price discrimination theory. Fringe sellers, however, do not appear to engage in price discrimination based on quality.
