A typology of Medicaid managed care

This article presents a typology for use in classifying and interpreting the findings of the growing empirical literature on managed care initiatives in the Medicaid program. Six key program attributes are identified for use in examining similarities and differences among these programs. Several alternative arrangements for each attribute are described from among the more than 60 different programs attempted. The typology is illustrated with five specific program designs, and selected empirical results from them are used to demonstrate how the typology can be employed.
