The Private Sector and Competition in Health Care Markets

: This paper reviews the historical trends in the regulatory and competitive approaches to containment of health care costs, covering efforts in both public and private sectors. The current interest in the potential of private-sector initiatives to stimulate competition in health care insurance and provider markets is highlighted. Since neither the workings of competition in health care nor the role and impact of the private sector in stimulating such competition are well understood, the concluding section discusses important research issues surrounding these topics.
