Fiona M. Scott Morton

Theodore Nierenberg Professor of Economics

Fiona M. Scott Morton is the Theodore Nierenberg Professor of Economics at the Yale School of Management, where she has been on the faculty since 1999. Her area of academic research is industrial organization, with a focus on empirical studies of competition. The focus of her current research is competition in healthcare markets and the economics of antitrust. From 2011–12, Professor Scott Morton served as the Deputy Assistant Attorney General for Economic Analysis (Chief Economist) at the Antitrust Division of the U.S. Department of Justice, where she helped enforce the nation’s antitrust laws. At Yale SOM, she teaches courses in the area of competitive strategy and antitrust economics. She served as Associate Dean from 2007–10 and has won the school’s teaching award three times. She founded and directs the Thurman Arnold Project at Yale, a vehicle to provide more antitrust programming and policy projects to Yale students. Professor Scott Morton has a BA from Yale and a PhD from MIT, both in Economics. She is a frequent speaker at seminars and conferences across the United States and Europe. 

Note: Professor Scott Morton occasionally writes research papers and undertakes other public work that present a potential appearance of a conflict of interest because of an overlap between the consulting topics and the particular ideas being discussed in the policy work or research paper. Her writing of this type includes a note in the appropriate place naming the companies at issue. In the spirit of full information, she wants to be sure the public is aware that she engages in some consulting work. This enables her to learn more about firm strategy and behavior, and contributes to better research and teaching.
