Deborah Haas-Wilson received her B.A. in economics from the University of Michigan at Ann Arbor, and her Ph.D. in economics from University of California at Berkeley.
Haas-Wilson's research focuses on competition and competition policies in health care markets. Her articles have appeared in the Journal of Political Economy, Journal of Economic Perspectives, Journal of Law and Economics, Review of Economics and Statistics, Journal of Health Economics, and other peer-reviewed journals. She is the author of Managed Care and Monopoly Power: The Antitrust Challenge (Harvard University Press, 2003) and co-editor of Uncertain Times: Kenneth Arrow and the Changing Economics of Health Care (Duke University Press, 2003).
Haas-Wilson works as an expert in health care antitrust, including cases involving the competitive effects of hospital mergers and commercial health insurer mergers, the effects of vertical consolidation in health care markets, and the competitive effects of physician mergers and networks. She has served as an expert on antitrust issues to the Federal Trade Commission (see for example, the Initial Decision (10/21/05) and the Opinion of the Commission (8/26/07) in the matter of Evanston Northwestern Healthcare Corporation), the Massachusetts Attorney General, and numerous private entities. In 2013, she testified in Federal District Court in Idaho on behalf of plaintiffs, in an antitrust lawsuit alleging competitive harm from St. Luke’s Health System’s acquisition of a large independent physician practice.
Professor Haas-Wilson was a recipient of the Robert Wood Johnson Foundation's Investigator Awards in Health Policy Research.
