Organizational Fragmentation and Care Quality in the U.S. Health Care System

Many goods and services can be readily provided through a series of unconnected transactions, but in health care close coordination over time and within care episodes improves both health outcomes and efficiency. Close coordination is problematic in the US health care system because the financing and delivery of care is distributed across a variety of distinct and often competing entities, each with its own objectives, obligations and capabilities. These fragmented organizational structures lead to disrupted relationships, poor information flows, and misaligned incentives that combine to degrade care quality and increase costs. We illustrate our argument with examples taken from the insurance and the hospital industries, and discuss possible responses to the problems resulting from organizational fragmentation.

Unhealthy Insurance Markets: Search Frictions and the Cost and Quality of Health Insurance

We analyze the role of search frictions in the market for commercial health insurance. Frictions increase the cost of insurance by enabling insurers to set price above marginal cost, and by creating incentives for inefficiently high levels of marketing. Frictions also lead to price dispersion for identical products and, as a consequence, to increases in the rate of insurance turnover. Our empirical analysis indicates that frictions increase prices enough to transfer 13.2% of consumer surplus from employer groups to insurers (approximately $34.4 billion in 1997), and increase employer group turnover by 64% for the average insurance policy. This heightened turnover reduces insurer incentives to invest in the future health of their policy holders. Our analysis also suggests that a publicly-financed insurance option might improve private insurance markets by reducing distortions induced by search frictions.
