Concurrences has published an article by AAI Vice President of Legal Advocacy Randy Stutz that challenges the Supreme Court’s framework for evaluating two-sided markets in the Court’s Ohio v. American Express (“Amex”) opinion. The article, “We’ve Seen Enough—It is Time to Abandon Amex and Start Over on Two-Sided Markets,” criticizes the Amex framework for failing to grapple with competition that occurs between one-sided and multi-sided firms. It was originally published as an AAI commentary in the aftermath of the Department of Justice’s defeat in attempting to block the merger of Sabre and Farelogix.
