Christina Romer’s speech on Monday had this overlooked bit, which I put into bold:
Our calculations showed that slowing the growth rate of health care costs by one and a half percentage points starting in 2014 would result in a budget deficit in 2020 that was 1 percent of GDP smaller than it otherwise would have been. By 2030, the impact is a reduction in the budget deficit of 3 percent of GDP; by 2040, it is a reduction of 6 percent of GDP.23 These estimates make vivid the notion that the number-one thing we can do to help get the long-run budget deficit under control is to slow the growth rate of health care costs.
Now, slowing the growth rate of costs will not solve all of our long-run budget problems. Our population is aging and even lowering the growth rate of health care costs quite substantially leaves them growing faster than GDP. As a result, other actions will also need to be taken. While health care reform may not be the “silver bullet,” it clearly must be a significant part of the solution to our deficit woes. It is the key step that we can take right now to bring the long-run budget problem down to manageable proportions.
Me: What “other actions” might she be referring to? Obviously higher taxes. Indeed, earlier in the speech she references the work of economists William Gale and Alan Auberach in this Brookings report:
Even if rising health care costs are an important component of the long-term problem, they are not necessarily “the” cause of the fiscal gap. The estimated gap is increased by more than 5 percentage points of GDP just by continuation of the policies that were enacted during the Bush Administration. … It will prove difficult to close the gap entirely via modifications to existing taxes and spending programs. A new revenue source, such as a value added tax (VAT), may be needed. A VAT imposed at a rate between 15 and 20 percent would essentially close the fiscal gap under the Administration’s budget.
