Managed Care and Monopoly Power

Book excerpt: As millions of Americans are aware, health care costs continue to increase rapidly. Much of this increase in health care costs is due to the development of new life-sustaining drugs and procedures, but part of it is due to the increased monopoly power of physicians, insurance companies, and hospitals, as the health care sector undergoes reorganization and consolidation. There are two tools to limit the growth of monopoly power: government regulation and antitrust policy. In this timely book, Deborah Haas-Wilson argues that enforcement of the antitrust laws is the tool of choice in most cases. Focusing on the economic concepts necessary to the enforcement of the antitrust laws in health care markets, Haas-Wilson provides a useful roadmap for guiding the future of these markets.
