There is limited empirical evidence about the impact of for-profit health insurers on various outcomes. I study the effects of conversions to for-profit status by Blue Cross and Blue Shield (BCBS) affiliates in 11 states, spanning 28 geographic markets. I find both the BCBS affiliate and its rivals increased premiums following conversions in markets where the converting affiliate had substantial market share. Medicaid enrollment rates also increased in these markets, a pattern consistent with "crowd in" of families who were formerly privately insured. The results suggest for-profit insurers are likelier than not-for-profit insurers to exercise market power when they possess it.
