The political economy of capitated managed care.
Despite the fact that billions of dollars are being invested in capitated managed care, it has yet to be subjected to the rigors of robust microeconomic modeling; hence, the seemingly intuitive assumptions driving managed care orthodoxy continue to gain acceptance with almost no theoretical examination or debate. The research in this paper finds the standard unidimensional model of risk generally used to analyze capitation--i.e., that risk is homogenous in nature, organizationally fungible, and linear in amplitude--to be inadequate. Therefore, the paper proposes to introduce a multidimensional model based on the assumption that phenomenologically unrelated species of risk result from non-homogenous types of socioeconomic activity in the medical marketplace. The multidimensional analysis proceeds to concentrate on two species of risk: probability risk and technical risk. A two-dimensional risk matrix reveals that capitation, far from being a market-oriented solution, actually prevents the formation of a dynamic price system necessary to optimize marketplace trades of medical goods and services. The analysis concludes that a universal attempt to purchase healthcare through capitation or any other insurance mechanism would render the reasonable attainment of social efficiency highly problematic. While in reality there are other identifiable species of risk (such as cost-utility risk), the analysis proceeds to hypothesize what a market-oriented managed care approach might look like within a two-dimensional risk matrix.
