The Importance of the Meaning and Measurement of 'Affordable' in the Affordable Care Act
August 11, 2011
A new working paper by researchers at the National Bureau of Economic Research highlights the practical importance of two critical but underexplored assumptions behind existing estimates of the Affordable Care Act's (ACA) potential impact on the mix of employees and families who may have employer-sponsored health insurance (ESI) in the future or may receive subsidies in the new health insurance exchanges.
The first assumption is whether ACA's affordable coverage rule will be interpreted to mean that employers must provide affordable single coverage or that they must provide affordable family coverage policies to workers with families to avoid paying a fine. The second assumption is how much employers and employees will cooperatively agree in the future to designing new compensation contracts to take advantage of the way "affordability" is determined.
- The researchers show that depending on these assumptions, the ACA could lead to far more lower to moderate income families gaining access to affordable coverage through exchanges or, conversely, to far fewer of these families being covered by ESI, even if no employers drop their health insurance plans as a result of the new law.
- They find at one extreme that the share of private sector workers covered by ESI would fall by as much as 12.7 percentage points, relative to a case of full compliance with the law, if the ACA affordability coverage rule is interpreted to apply to family coverage and employees directly pay 100 percent of the cost of the ESI in premiums, with compensating higher wages making them no worse off.
- At the other extreme, they find no changes in the share of private sector workers covered by ESI along this margin if employee contribution shares do not change in the future and affordability is interpreted to refer to single coverage.
