This brief describes alternative forms of subsidized reinsurance and the mechanisms by which they spread risk and reduce premiums. For a given amount of funding, a particular program’s efficacy will depend on how it affects insurers’ risk and the risk margins built into premiums, incentives for selecting or avoiding risks, incentives for coordinating and managing care, and the costs and complexity of administration. These effects warrant careful consideration by policymakers as they consider measures to achieve stability in the individual market in the long term.
