AAI experts Richard Brunell and Diana Moss both penned articles for the Fall 2018 issue of Antitrust Magazine. The issue features multi-perspective analysis of the Supreme Court’s decision in Ohio v. AMEX. Brunell’s article points out the uncertainties raised by the decision but argues that the decision is actually quite limited in scope and may not be as bad for antitrust enforcement as some contend. Also in the issue is a piece by Moss, highlighting the importance of an active progressive agenda to address rising concentration. Moss emphasizes that while measures of rising concentration may be at more aggregate levels, their implications for antitrust should be explored, not ignored or minimized.
