Hey! Deficit Hawks! Adding a Public Plan to the PPACA Is Low-Hanging Fruit!

Doug Elmendorf Writes to Pete Stark: Taking into account all of the relevant factors, CBO estimates that roughly one-third of the people obtaining coverage through the insurance exchanges would enroll in the public plan. CBO estimates that about 25 million people would purchase coverage individually through the exchanges in the 2017– 2019 period under the proposal; in addition, about 13 million people would be expected to obtain employment-based coverage through the exchanges —so total enrollment in exchange plans would be about 38 million. Total enrollment in the public plan would thus be roughly 13 million. Given all of the factors at work, however, those estimates are subject to an unusually high degree of uncertainty.
Compared with projections of enrollment under current law for the 2017–2019 period, CBO estimates that about three-quarters of a million more people would obtain individually purchased coverage and about three-quarters of a million fewer would have employment-based coverage. The proposal would have minimal effects on the number of people with other sources of coverage and on the number of people who would be uninsured.
CBO and the staff of the Joint Committee on Taxation (JCT) estimate that the proposal would reduce federal budget deficits through 2019 by about $53 billion. That estimate includes a $37 billion reduction in exchange subsidies and a $27 billion increase in tax revenues that would result from changes in employment-based coverage, partly offset by an $11 billion increase in costs for providing tax credits to small employers. (The proposal would have minimal effects on other outlays and revenues related to the insurance coverage provisions of PPACA.) The bulk of those effects would occur in the second half of the decade; the savings estimated for 2019 are about $14 billion. Although CBO and JCT have not yet extended to 2020 the models they use to estimate insurance coverage, the proposal would probably reduce the federal budget deficit by about $15 billion in that year, bringing the total budgetary savings through 2020 to about $68 billion...
