Contributor(s): Professor Robert J Shiller | Robert Shiller, who warned of both the tech and housing bubbles, now cautions that signs of irrational exuberance among investors have only increased since the 2008–9 financial crisis. With high stock and bond prices in the United States, and rising housing prices in many countries, the post-subprime boom may well turn out to be another illustration of Shiller’s influential argument that psychologically driven volatility is an inherent characteristic of all asset markets. Robert J Shiller (@RobertJShiller), the recipient of the 2013 Nobel Prize in economics, is a best-selling author, a regular contributor to the Economic View column of the New York Times, and a professor of economics at Yale University. His books include Finance and the Good Society, Animal Spirits (co-written with George A. Akerlof), The Subprime Solution, and The New Financial Order (all Princeton). This event marks the publication of a new edition of Irrational Exuberance.
