Drawing on his 45 years at the center of international economic policy debates, C. Fred Bergsten argues in his lecture that currency manipulation is the single biggest challenge facing the world economic system and costs millions of jobs. Bergsten offers bold proposals for countervailing intervention and ties between the International Monetary Fund and the World Trade Organization in evaluating currency misalignments. He will be joined in discussion by Rohinton Medhora, CIGI President.
