Network Incentives in Managed Health Care
This paper introduces a theory of network incentives in managed health care. Participation in the plan's network confers an economic benefit on providers; in exchange, the plan expects compliance with its protocols. The network sets a target for the number of outpatient visits in an episode of care. A provider failing to satisfy the target may be penalized by the plan's attempt to direct patients to other providers within its network. There is an equilibrium in which every provider in the network uses the target. We test the theory by observing behavior of providers before and after the introduction of managed mental health care in a large, employed population. Managed care consisted of price reductions, utilization review, and creation of a network. Quantity per episode of care fell sharply after initiation of managed care. We identify a network effect in our empirical work. The results indicate that in this case, network incentives account for most of the quantity reduction due to managed care.
