Repealing Obamacare would spur the economy, adding more than half a percent to the gross domestic product at the beginning of the next decade, the Congressional Budget Office said in a new analysis Friday that still found repeal would be bad for the federal deficit.

Tens of millions of Americans would lose coverage they’d have under the Affordable Care Act over the next decade, but that loss would chase many of them back into the labor pool, where they would both get insurance through their jobs, and would lead to other current workers putting in more time on the job.

Combined, those would produce an economic boost equal to seven tenths of a percent from 2021 to 2025, the CBO said.

“The subsidies and tax credits for health insurance that the ACA provides to some people are phased out as their income rises — creating an implicit tax on additional earnings — and those subsidies, along with expanded eligibility for Medicaid, generally make it easier for some people to work less or to stop working without losing health insurance coverage. For other people, the act directly imposes higher taxes on labor income, thus discouraging work. Repealing the ACA would reverse those effects,” the CBO said.

It’s the second major report this week from the budget agency and its new director, Keith Hall. The first one, looking at the long-term budget outlook, said the federal fiscal picture is in bad shape and will need major help — and the sooner the better.
