 abstract = {This paper examines consolidation in the Massachusetts hospital market.  We find that consolidation is driven primarily by a large decline in the demand for hospital beds, resulting from increased enrollment in managed care and technological changes. The drive to consolidate appears through three primary forces: consolidation for closure; consolidation for economies of scale; and consolidation for network creation.},
