At a time when the economy is stalled, it makes sense for the federal government to consider running a deficit to help stimulate growth.
Few will argue this point. Even deficit hawks like me.
The problem with current policy, however, lies not in the short-term. It is with the long-term assumption that the federal government will run large deficits well into the future because of its tax cut and spending policies.
A recent study by the Urban-Brookings Tax Policy Center's William Gale and Peter Orszag explains the long-term costs associated with a lack of fiscal discipline:
Based on the literature, a reasonable estimate is that a reduction in the projected budget surplus (or increase in the projected budget deficit) of one percent of GDP will raise long-term interest rates by between 50 and 100 basis points. These findings suggest that the costs of increased deficits are significant over the long run, and need to be compared carefully to the potential benefits of the tax and spending programs that result in larger long-term deficits.
Long-term deficits are bad. They lead to a hidden tax on every American through higher interest rates. Higher interest rates, of course, can slow economic growth.
Some, however, will accept deficits as long as they also serve one political party's narrow ideological desires.
