Irrational Exuberance

《非理性繁荣》书名取自美国联邦准备理事会理事主席葛林史班 1996 年底在华府希尔顿饭店演讲中，谈到当时美国金融资产价格泡沫时所引用的一句名言。从那时起，许多学者、专家都注意到美国股市因投机风气过盛而引发的投资泡沫现象。

Book Description

In this timely and prescient update of his celebrated 2000 bestseller, Robert Shiller returns to the topic that gained him international fame: market volatility. Having predicted the stock market collapse that began just one month after the first edition was published, he now expands the book to cover other markets that have become volatile, particularly the recently red-hot housing market. He includes a full chapter on domestic and international housing prices in historical perspective.

Shiller amasses impressive evidence to support his argument that the recent housing market boom bears many similarities to the stock market bubble of the late 1990s, and may eventually be followed by declining home prices for years to come. After stocks plummeted when the bubble burst in 2000, investors moved their money into housing. This precipitated the inflated real estate prices not only in America but around the world, Shiller maintains. Hence, irrational exuberance did not disappear—it merely reappeared in other settings.

Building on the original edition, Shiller draws out the psychological origins of volatility in financial markets, this time folding real estate into his analysis. He broadens the evidence that investing in capital markets of all kinds in the modern free-market economy is inherently unstable—subject to the profoundly human influences captured in Alan Greenspan’s now-famous phrase, “irrational exuberance.” As was true of its predecessor, the second edition of Irrational Exuberance is destined to be widely read, discussed, and debated.

CNBC, day trading, the Motley Fool, Silicon Investor--not since the 1920s has there been such an intense fascination with the U.S. stock market. For an increasing number of Americans, logging on to Yahoo! Finance is a habit more precious than that morning cup of joe (as thousands of SBUX and YHOO shareholders know too well). Yet while the market continues to go higher, many of us can't get Alan Greenspan's famous line out of our heads. In Irrational Exuberance, Yale economics professor Robert J. Shiller examines this public fascination with stocks and sees a combination of factors that have driven stocks higher, including the rise of the Internet, 401(k) plans, increased coverage by the popular media of financial news, overly optimistic cheerleading by analysts and other pundits, the decline of inflation, and the rise of the mutual fund industry. He writes: "Perceived long-term risk is down.... Emotions and heightened attention to the market create a desire to get into the game. Such is irrational exuberance today in the United States."

By history's yardstick, Shiller believes this market is grossly overvalued, and the factors that have conspired to create and amplify this event--the baby-boom effect, the public infatuation with the Internet, and media interest--will most certainly abate. He fears that too many individuals and institutions have come to view stocks as their only investment vehicle, and that investors should consider looking beyond stocks as a way to diversify and hedge against the inevitable downturn. This is a serious and well-researched book that should read like a Stephen King novel to anyone who has staked his or her future on the market's continued success.

From The New Yorker

During the past decade, he has emerged as a leader in the new field of "behavioral finance" which seeks to apply lessons learned from other academic disciplines, particularly psychology to economics. Irrational Exuberance is not just a prophecy of doom. Encompassing history, sociology, and biology, as well as psychology and economics, it is a serious attempt to explain how speculative bubbles come about and how they sustain themselves.

From Library Journal

Taking his book's title and thesis from Alan Greenspan's 1996 description of investors, Shiller (economics, Yale Univ.) studies the current booming U.S. stock market in historical terms. His research into past U.S. and international markets indicates that during every speculative bubble there was always widespread consensus that high valuations were justified by each market's special circumstances. Every large market correction seemed to result from popular consensus rather than specific events or news. Shiller says that past bull and bear markets, though often based initially on sound fundamental reasoning, fed upon themselves to go beyond what the facts justified. He challenges the efficient market theory, demonstrating that markets cannot be explained historically by the mo
