Global deals require global antitrust clearance, and that clearance invariably involves Washington, Brussels, and economics. In this NERA seminar, leading antitrust experts offered perspectives from both sides of the Atlantic on what US counsel needs to know about the fast-evolving role of economics in merger control in these jurisdictions and beyond. NERA Affiliated Academic Dr. Michael Baye, former Director of the Bureau of Economics at the US Federal Trade Commission, shared his insights into how economics informs antitrust clearance -- and how the role of economics is being transformed in the US and the EU. Senior Vice President Dr. Ramsey Shehadeh, one of NERA's foremost experts on US merger control, moderated the session.
