Abstract
This paper studies a market for a medical product in which there is perfect competition among health insurers, while the good is sold by a monopolist. Individuals di§er in their severity of illness and there is ex post moral hazard. We consider two regimes: one in which insurers use coinsurance rates (ad valorem reimbursements) and one in which insurers use copayments (speciÖc reimbursements). We show that the induced equilibrium with copayments involves a lower producer price and a higher level of wel- fare for consumers. This results provides strong support for a reference price based reimbursement policy.
