David S. Sibley is the John Michael Stuart Centennial Professor of Economics at the University of Texas at Austin. In addition to his current teaching responsibilities, he has taught graduate level courses in economics at the University of Pennsylvania and Princeton University. Prior to joining the University of Texas, he was Head of the Economics Research Group at Bell Communications Research, and served as a Member of the Technical Staff in economics at Bell Laboratories.

In October 2004, he completed an eighteen-month term as Deputy Assistant Attorney General for Economic Analysis in the Antitrust Division of the U.S. Department of Justice, the highest-ranking economics position in the Antitrust Division. While at the Antitrust Division, he supervised all economic analysis within the Division (including both merger and non-merger investigations) and directed the Divisionís Economic Analysis Group. In this capacity, he contributed to the economic analysis of general policy issues, such as vertical restraints, including bundled loyalty discounts and vertical mergers. He also represented the U.S. in OECD discussions on vertical foreclosure.

During the last thirty years, Professor Sibley has carried out extensive research in the areas of industrial organization, microeconomic theory, and regulation. His publications have appeared in a number of leading economic journals, including the Journal of Economic Theory, Review of Economic Studies, Rand Journal of Economics, American Economic Review, Econometrica, and the International Economic Review, among others. He is also a co-author (with Steven J. Brown) of a leading textbook on monopoly pricing, The Theory of Public Utility Pricing, which was published by Cambridge University Press.

He has consulted extensively for various firms and agencies, both in the United States and abroad, on antitrust and regulatory matters. He served as a consultant to the Antitrust Division of the U.S. Department of Justice in the Microsoft antitrust case, including both trial and remedy phases. He has also served as a consultant to the U.S. Federal Trade Commission on several matters involving the competitive effects of horizontal and vertical mergers.

Professor Sibley received his Ph.D. in economics from Yale University and a B.A. in Economics from Stanford University.
