Irrational exuberance / Robert J. Shiller (cop. 2015)

Irrational exuberance de Robert J. Shiller In this revised, updated, and expanded edition of his New York Times bestseller, Nobel Prize–winning economist 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. In other words, Irrational Exuberance is as relevant as ever. But Irrational Exuberance is about something far more important than the current situation in any given market because the book explains the forces that move all markets up and down. It shows how investor euphoria can drive asset prices up to dizzying and unsustainable heights, and how, at other times, investor discouragement can push prices down to very low levels.
