Reinharts, Rogoff See Huge Output Losses From High Debt

The U.S. and other developed economies with high public debt potentially face “massive” losses of output lasting more than a decade, even if their interest rates remain low, according to new research by economists Carmen and Vincent Reinhart and Kenneth Rogoff.

In a paper published today on the National Bureau of Economic Research’s website, they found that countries with debts exceeding 90 percent of the economy historically have experienced subpar economic growth for more than 20 years. That has left output at the end of the period a quarter below where it would have been otherwise.
