title: Hospitals and antitrust: defining markets, setting standards.
abstract: The definition of geographic and product markets is a critical aspect of any antitrust analysis. This paper argues for a different approach to market definition in areas where insurance plans that contract selectively are a significant market presence. Such a proposed approach is described and some policy implications are drawn.
