Economics is not exact science: Robert J Shiller
Robert J Shiller, professor at Yale University and also a runner-up for nobel prize in economics, discusses global economy with NDTV's Namrata Brar on the sidelines of the World Economic Forum in Davos, Switzerland. He says with the European economy still unsettled and undergoing national debt resolution and the US economy underperforming, it may take a while for the weakened overall business confidence around the world to recover.
