Ancient man worshipped it. Governments stockpile it. Warren Buffett disdains it. And Mr. T loves it. For millennia gold has long been one of the most valuable commodities on earth, and until 1971 served as the basis of our own U.S. dollar. As its price continues to skyrocket in the face of an uncertain global economy and unstable currencies, what is the future of gold as a commodity and, even possibly, money? In his new e-book IN GOLD WE TRUST? The Future of Money in an Age of Uncertainty (The Economist / Amazon Kindle Singles, March 2012 – co-written with The Economist’s Matthew Bishop), economist Michael Green uses the surge in the price of gold in recent years as a lens to explore the future of money. Green was formerly a senior official in the British government where he worked in aid and development. Prior to that he worked in Poland, teaching economics at Warsaw University and as a freelance journalist. A graduate of St Peter's College, University of Oxford, he lives in London.
