This paper examines the effects of laws mandating that health insurance cover specific conditions, procedures, providers, and beneficiaries. Unlike previous work, this paper considers the market for employer-based health insurance rather than the much smaller individual market, and uses a panel data approach to account for unobserved heterogeneity among states. Using a fixed effects model, I find that the average mandate increases premiums by 0.44–1.11 percent annually. This implies that new mandates were responsible for 9–23 percent of all premium increases over the 1996–2011 period.
