We study the effect of physician incentives in an HMO network. Physician incentives are controversial because they may induce doctors to make treatment decisions that differ from those they would chose in the absence of incentives. We set out a theoretical framework for assessing the degree to...

We study the economics of employment relationships through theoretical and empirical analysis of an unusual set of firms, large law firms. Our point of departure is the quot;property rightsquot; approach that emphasizes the centrality of ownership's legal rights to control important, non-human...

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 U.S. healthcare system because the...

Economic models of incentives in employment relationships are based on a specific theory of motivation: employees are "rational cheaters," who anticipate the consequences of their actions and shirk when the marginal benefits exceed costs. We investigate the "rational cheater model" by observing...

Our point of departure is the "property rights" approach that emphasizes the centrality of ownership's legal rights to control important, non-human assets of...

We analyze the effect of search frictions in the market for commercial health insurance. Frictions increase insurance premiums (enough to transfer 13.2 percent of consumer surplus from fully insured employer groups to insurers—approximately $34.4 billion in 1997); and increase insurance...

Employers structure pay and employment relationships to mitigate agency problems. A large literature in economics documents how the resolution of these problems shapes personnel policies and labor markets. For the most part, the study of agency in employment relationships relies on highly...
