Sizing Up Exchange Market Competition
Issue Brief
This issue brief offers an early look into how competitive the health insurance exchanges (also called marketplaces) are under the Affordable Care Act in selected states. Through analysis of enrollment data released by seven states (California, Connecticut, Minnesota, New York, Nevada, Rhode Island, and Washington) this brief finds that exchange markets in California and New York are shaping up to be more competitive than their individual markets were in 2012 while those of Connecticut and Washington show less competition (less even market share distribution). In several states, market concentration of individual insurers have shifted significantly compared to the individual market prior to the ACA, pointing to the potential for greater price competition in the future and the influence of new entrants to the market.
