Nouriel Roubini : We have been talking about a G-0 world because there are all these global economic issues in which there is disagreement between provincial powers on monetary policy, fiscal policies, exchange rates, currency wars, global imbalances, how to reform the international system of surveillance of the banks, reforming international financial systems, energy, food security and all the geopolitical issues. On all of these issues we need more coordination and cooperation within the great powers. There is a division of views not just between U.S. and China, but Japan and Europe on fundamental currency issues. - in Davos 2013
