As shown, the effects are largely centered around the subsidized population. The driving factor in each scenario is whether it lowers APTC amounts, and, if so, by how much. For example, Scenario 1 would not affect APTC amounts, which suggested a generally positive outlook for the subsidized population. Benefits would also accrue to 3 million individuals who do not receive federal subsidies.
Implications
The analysis suggests that provider reimbursement rates and the resulting premium amounts play a significant role in affordability, enrollment, and federal government savings. In a vacuum, decisions around rate and premium setting could mean the difference between an overall increase or decrease in the general welfare.
However, premium amounts are not the only factor in determining the overall impact of a public option program. As RAND indicates, its analysis does not speak to the effects of States reinvesting federal savings on affordability and enrollment. In fact, in its assessment, RAND states that “the number of people better off outweighs the number who are worse off,” likely drawing on the assumption that States would use any realized savings to improve coverage affordability. Moreover, additional elements such as benefit design; mandated versus voluntary provider participation; and, whether one or many carriers participate in a particular public option program all have affordability implications as well.
As such, it will be important for any designer of a public option program to consider these additional elements in tandem with rate setting decisions. In addition, public option program designers must also have a clear understanding upfront of the population they primarily wish to serve (e.g., subsidized versus unsubsidized individuals) and their program goals (e.g., expanded coverage, increased affordability, increased quality, and/or robust access to provider networks). Such a multi-variate understanding will then inform the decisions a designer must make, especially when trade-offs are involved.
