Evans, Charles

Evans said that based on the outlook for rising unemployment, falling industrial production and a wider output gap, economic models suggest rates should be below zero.

"If it were not constrained by zero, those models would want to push it below zero, but that's not possible," Evans told reporters after a panel at the American Economic Association's meeting in San Francisco.

Quantitative easing, a way to flood the banking system with large amounts of money, "is a way to mimic below-zero rates and provide support to the economy," he said.
