Abstract

We study the Medicare Part D prescription drug insurance program as a bellwether for designs of private, non-mandatory health insurance markets that control adverse selection and assure adequate access and coverage. We model Part D enrollment and plan choice assuming a discrete dynamic decision process that maximizes life-cycle expected utility, and perform counterfactual policy simulations of the effect of market design on participation and plan viability. Our model correctly predicts high Part D enrollment rates among the currently healthy, but also strong adverse selection in choice of level of coverage. We analyze alternative designs that preserve plan variety.
