Now, some prominent economists say U.S. deficits don’t matter so much after all, and it might not hurt to expand them in return for beneficial programs such as an infrastructure project.
“The levels of debt we have in the U.S. are not catastrophic,” said Olivier Blanchard, an economist at the Peterson Institute for International Economics. “We clearly can afford more debt if there is a good reason to do it. There’s no reason to panic.”
Mr. Blanchard, also a former IMF chief economist, delivered a lecture at last month’s meeting of the American Economic Association where he called on economists and policymakers to reconsider their views on debt.
The crux of Mr. Blanchard’s argument is that when the interest rate on government borrowing is below the growth rate of the economy, financing the debt should be sustainable.
Market interest rate signals can be misleading and dangerous. By blessing the U.S. with such low rates now, he says, financial markets just might be “giving us the rope with which to hang ourselves.”
