In this piece, Noreena Hertz asks members of the G20 to abandon their faith in free trade. "They know that they are facing the greatest global economic crisis ever," she writes. "They acknowledge that the crisis was man-made...They are nervously conscious that decisions will have to be made without reference to the very tools and theories that they have relied on for the past thirty years. She goes on to say that "We also continue to be presented with a false dichotomy - free trade versus protectionism. What we actually need is a nuanced analysis of where on the free trade/protectionism scale individual nations need and want to be positioned, and what the implications of that would be."
