title: Emerging issues in the antitrust definition of healthcare markets.
abstract: Managed care has shifted purchasing decisions from patients towards payers. While this shift has been associated with increased price competition in provider markets, we believe that it may enhance the potential for consumer injury from mergers in geographic markets previously considered immune to antitrust concerns (e.g. suburban components of large metropolitan areas). In addition, recent changes also increase concerns about mergers in product submarkets such as tertiary care.
