Effects of Implementing State Insurance Market Reform, 2011-2012. Conclusions


These limitations inform readers to view study findings with some caution. Nonetheless, we saw statistically significant differences in the levels of premium rate increases during different periods of time. Premium increases slowed substantially in the individual and small group markets after rate review went into effect. Results show that, on average, for the states included in our sample, insurers requested smaller premium increases after the implementation of rate review, and on average, for the states included in our sample, regulators reduced these requests significantly. The relatively large number of filings submitted before September 1, 2011, plus subsequent declines in premium increases in 2012 is consistent with the idea that insurers changed their approach after the ACA’s rate review went into effect.
