In her law journal article Amazon’s Antitrust Paradox, Lina Khan argued, using Amazon as an example, that current antitrust doctrine cannot identify certain types of anticompetitive conduct in platform and data-driven markets and, consequently, reforming antitrust is necessary to correct these deficiencies. Khan’s analysis of Amazon’s conduct and the conclusions she drew from it are flawed because she ignored or misapplied the economics of two-sided markets, mischaracterized competitive conditions, and did not consider the pro-competitive effects of Amazon’s conduct. In this article, we review the economics of two-sided markets and then assess Khan’s analysis of alleged predation in e-books and in the online sale of diapers, as well as alleged anticompetitive implications of Amazon’s vertical integration into logistics and its use of data. A careful assessment of Amazon’s conduct does not support Khan’s conclusion that antitrust reform is necessary because she has not demonstrated that Amazon’s conduct is anticompetitive.

I review the literature on eCommerce platforms with particular emphasis on the antitrust debate on Amazon. The business model of hybrid marketplaces is based on monetization through fees on third party sellers hosted on the platform and direct margins on own products. Recent theoretical and empirical work on endogenous marketplace structures has analyzed the welfare impact of the dual mode and of recommendation algorithms that have been associated with self‐preferencing strategies. The trade offs are complex and one cannot easily conclude that Amazon entry is biased to expropriate third party sellers or that a ban on dual mode, self‐preferencing or copycatting would benefit consumers.
