Chris Sagers, the James A. Thomas Distinguished Professor of Law, will present as part of a conference this weekend at the NYU School of Law’s Classical Liberal Institute, entitled “Understanding the Visible: The Undisputed Facts and Disputed Law of Platform Antitrust.” Also presenting will be NYU presenters Richard Epstein, Eleanor Fox, Harry First, Mario Rizzo, and several other leading scholars of antitrust and economics.

His paper, “Platforms, American Express, and the Problem of Complexity in Antitrust,” asks whether it was wise for the Supreme Court in last year’s Ohio v. American Express to adopt the so-called “platform” or “two-sided markets” theory as a way of analyzing antitrust issues in credit cards and other payment systems.
