Economic power player Nouriel Roubini, of Roubini Global Economics, appeared on CNBC’s Squawk Box yesterday with Paul Britton, founder and CEO of Capstone Holdings, to discuss the stability of the U.S. economy. “A lot of the volatility has been repressed,” Roubini said. “Once the policy stimulus goes away we’ll have to see whether there’s enough robustness in private demand to have a sustained economic recovery. I’m skeptical.” Britton said he worries that policy decision in the near future will wind up being good for politics and bad for the economy. He said the mid-term elections in November and the campaigns leading up to them will each have a major impact on economic markets nationwide.
