Justin Fox is Executive Editor, New York, of the Harvard Business Review Group and senior fellow at the Mossavar-Rahmani Center for Business and Government at Harvard Kennedy School. He is the author of The Myth of the Rational Market: A History of Risk, Reward, and Delusion on Wall Street and writes a blog for hbr.org. Before joining HBR Group in 2010, he wrote a weekly column for Time and created the Curious Capitalist blog for Time.com. Previously, Fox spent more than a decade working as a writer and editor at Fortune magazine, where he covered economics, finance, and international business.
The Myth of the Rational Market tells the story of the rise and fall of the efficient market hypothesis, the influential but flawed academic theory that financial market prices are rational and correct. The book has been a New York Times and Wall Street Journal bestseller, and a New York Times Notable Book of 2009. It was named the best business book of 2009 by the editors of Amazon.com. In the New York Times Book Review, Paul Krugman called it “a must-read for anyone who wants to understand the mess we’re in,” while in the Wall Street Journal Burton Malkiel described it as “a valuable and highly readable history of risk and reward.”
Fox has been a frequent commentator on the Nightly Business Report on PBS, public radio's Marketplace, Dutch radio's Met het oog op morgen, and all the U.S. cable news and business networks. Most important, he’s been a guest on Comedy Central’s The Daily Show With Jon Stewart.
Before joining Fortune, Fox worked at several newspapers, including American Banker and the Birmingham (Ala.) News. He was a Young Global Leader of the World Economic Forum, before he got too old, and is a graduate of Princeton University. He lives in Manhattan with his wife and son.
