Study: Mandate delay won't hurt ObamaCare's bottom line

"Eliminating the employer mandate has very little effect on the distribution of coverage; it remains virtually identical to  the case when the full ACA is in effect," the study's authors wrote.

Eliminating the individual mandate, however, would have severe consequences for the healthcare law's success. 

Republicans will offer proposals this week to delay the individual mandate along with the employer mandate, arguing that it's unfair to require people to buy insurance while giving employers a break from the requirement to buy it.

But actually postponing or eliminating the individual mandate would wreak havoc on the law's core policies and would likely cause insurance premiums to rise dramatically.

Implementing the Affordable Care Act without the individual mandate would reduce the number of people gaining access to coverage by about 14 million, according to the Urban Institute's analysis.
