Title: "The Optimal Geographic Distribution of Managed Competition Subsidies"

Abstract: When markets fail to provide socially optimal outcomes, governments often intervene through 'managed competition' where firms compete for per-consumer subsidies. We introduce a framework for determining the optimal market-level subsidy schedule that features heterogeneity in consumer preferences and inertia, and firms with heterogeneous costs that can set prices and product characteristics in response to changes in the subsidy. We apply it to the Medicare Advantage program, which offers Medicare recipients private insurance that replaces Traditional Medicare. We calculate counterfactual equilibria as a function of the subsidies by estimating policy functions for product characteristics from the data and solving for Nash equilibria in prices. The consumer-welfare-maximizing budget-neutral schedule increases per-beneficiary annual consumer welfare by 113% over the current policy (an aggregate increase of $5.2 billion per year) and is well-approximated with a linear rule using market-level observables.
