Kenneth S Rogoff teaches in the Economics Department of Harvard University where he is Thomas D Cabot Professor of Public Policy.During 2001-2003 Rogoff was chief economist at the Internatonal Monetary Fund. His newest book The Curse of Cash, shows why phasing out most (except for small bills) would likely significantly reduce crime and tax evasion, while also helping central banks fight financial crises. His 2009 book, with Professor Carmen M Reinhart of the University of Maryland, was a NY Times and Amazon best seller; it exploits an extensive new database, developed by the authors over many years, and now widely used by researchers, policymakers and investor. Reinhart and Rogoff show the remarkable quantitative similarities in deep financial crises across time and regions. Rogoff's 1996 treatise with Maurice Obstfeld on the Foundations of International Macroeconomics remains the standard graduate reference in the field. His monthly column on global economic issues is published in over fifty countries and a dozen languages. He is also a frequent commentator in the media, including NPR, BBC, The Financial Times, the Wall Street Journal, CNN, CNBC and Bloomberg. Outside economics, Rogoff was awarded the life title of international grandmaster of chess by the World Chess Federation in 1978. He is married to Natasha Lance Rogoff, and has two children, Gabriel and Juliana.
