  1. A model of the impact of reimbursement schemes on health plan choice.

    Article - En anglais

    Flat capitation (uniform prospective payments) makes enrolling healthy enrollees profitable to health plans.

    Plans with relatively generous benefits may attract the sick and fail through a premium spiral.

    We simulate a model of idealized managed competition to explore the effect on market performance of alternatives to flat capitation such severity-adjusted capitation and reduced supply-side cost-sharing.

    In our model flat capitation causes severe market problems.

    Severity adjustement and to a lesser extent reduced supply-side cost-sharing improve market performance, but outcomes are efficient only in cases in which people bear the marginal costs of their choice.
