The US economy is entering a two-year recession that will be longer and deeper than previously feared, said Nouriel Roubini, a well-known economist and professor at New York University.
"I believe we're going to have two years of negative economic growth," Roubini said on CNBC. "The last two recessions lasted only eight months each ... This time around this is going to be three times as long, three times as deep. This is going to be the worst recession the US has experienced since the 1980s."
