Abstract
The Affordable Care Act requires health insurance plans to offer coverage without annual limits. This requirement began to be enforced in September of 2010, but some employers received special waivers that delayed the start of enforcement for them. Using data from the Center for Research in Security Prices (CRSP), we conduct an event study of the stock prices of these companies as their waivers were announced. We find that waivers do not lead to a statistically significant increase in the stock prices of waiver recipients.
