Antitrust Analysis of Platform Markets: Why the Supreme Court Got It Right in American Express

David Evans and Richard Schmalensee

December 2019

David Evans and Richard Schmalensee explore the implications of the US Supreme Court’s seminal decision on the antitrust analysis of platform markets. They argue that the Court got it right in concluding that courts must take full account of the multisided nature of certain markets and the platform businesses that compete in them, and that criticisms of the decision are not supported by modern economics.
