Accountable Care Organizations (ACOs) are a new model for integrated health care delivery created by the Patient Protection and Affordable Care Act. They allow a group of hospitals and providers to jointly contract with the Center for Medicare and Medicaid Services to provide care to a population of Medicare enrollees in an environment that rewards cost-efficiency through shared savings so long...

The interplay of within-group free-riding and across-group competition allows for a wide variety of equilibria, according to how well groups are able to overcome internal free-riding. In a symmetric model we derive equ...
