Insurers’ Negotiating Leverage and the External Effects of Medicare Part D
AbstractBy influencing the size and bargaining power of private insurers, public subsidization of private health insurance may project effects beyond the subsidized population. We test for such spillovers in Medicare Part D by analyzing how resulting increases in insurer size affected drug prices negotiated in the non-Medicare commercial market. On average, Part D lowered prices for commercial enrollees by 5.3%. The external commercial market savings amount to $2.6 billion per year, which, if passed to consumers, approximates the cost-savings of newly-insured subsidized beneficiaries. If retained by insurers, it corresponds to an 8% average increase in profitability.
