As Robert Shiller’s new 2009 preface to his prescient classic on behavioral economics and market volatility asserts, the irrational exuberance of the stock and housing markets “has been ended by an economic crisis of a magnitude not seen since the Great Depression of the 1930s.” As we all, ordinary Americans and professional investors alike, crawl from the wreckage of our ...more

I really battled to get into this book. I didn't enjoy it at all. We all know that market bubbles exist and I really don't think Robert Shiller added much to the discussion (I will no doubt come under fire here from all the fans out there). This was summed up for me in the last chapter when he listed things that could go wrong in the future. He listed every conceivable scenario in the world. While I agree that you need to consider all possibilities and investing is about probabilities, it is in ...more

This is a book that needs to be reread in order for the points to absorbed.

Shiller starts out with three chapters that present statistics showing that stocks and real estate are not investments that people can count on to earn a good long-run return. He shows that if people got into the market at the wrong time they could end up having to wait for a long time before the value of stocks returned to the price that people paid for the stocks. He shows similar statistics for real estate.

This book serves as an awakening call from "the present...whiff of extravagant expectation, if not irrational exuberance, in the air. People are optimistic about the stock market. There is a lack of sobriety about its downside and the consequences that would ensue as a result." The author advances that "we need to know if the price level of the stock market today, tomorrow, or any other day is a sensible reflection of economic reality, just as we need to know as individuals what we have in our ...more

Two subjects I love: finance and psychology. Which is called behavioral finance, but whatever.

All I can say is, I read the wrong edition. Ugh. The third edition is Shiller's grand middle finger to the markets after the crash of 08/09 and subsequent recession. I should have read that instead, but this was a solid, still relevant (and eerily prophetic) blast from the past.

I read this because I got to have dinner with Shiller recently and I wanted a reminder of his theories. I wonder if it's outdated or it's still true that markets are over priced. I think he's absolutely right that they're not efficient, but is it time to sell? He said he didn't know.

Stock market, bond market and real estate market. When, where and why in a bubble? What is psychology's role into the markets? Is it really efficient markets? In-depth coverage with historical case studies and comparison studies of trends of different markets shed loads of light into the subject. Suitable for business graduates (banking, finance, accounting, etc.). The appendix (The author's Noble Prize Speech) is a bit advanced and can be skipped in case you can't withstand too much ...more

Robert Shiller is my favorite person to see interviewed on economics. He chooses his words carefully, always saying the economy is unpredictable while being heralded as a prophet. No matter how many times he stares into a camera and tells people he has never predicted the future of the economy, people still believe the myths. Like Kurt Cobain yelling songs about how much he hates his job and fans while growing more popular by the hour.

So I've been wanting to read this book for years. I've read

I very much enjoyed this book. It may seem a bit dry to a non-economist (and admittedly even to me, an economist), but it offers a brilliant overview on financial economics and gives you a good idea why Shiller was awarded the Nobel prize in 2013.

It also offers a nice perspective on the economic climate between recession as the second edition was published in 2005 (the third ed is out now, 2015) and so it contains new material compared to the very first edition that came out just before the .com

Shiller is rare among economists both for his sense of history and his openness to engaging with other disciplines (qualities that he shares with Thomas Piketty). In the first edition of this book, published in 2000, Shiller argued that the stock market was in the midst of a bubble. What is now known as the Dot-Com Bubble ended just as it was published. In the second edition, published in 2005, Shiller argued that the housing market was overvalued. In this edition, he argues that the stock ...more

A little dry for me. I actually ended up skimming through most of it because you could get the main point of each chapter in each chapters' final paragraph.

I can see why this is a popular book, as Shiller discusses a lot of history about the stock market. However, I do not feel as though I've really learned any new aspects about the markets, besides some small details of history discussed.

If you're reading this book then you probably already know that there's more to the stock market than luck,

One of the best books on investments ever written. I wish I had read this when I was younger, rather than reading books like 'the Dow 20,000' etc. Painful lessons learnt.

This was pretty interesting and well written. The 3rd edition, updated in 2014 includes material on the 2008 mortgage driven crisis and even current "state of the economy" in 2014.
Shiller speaks very lightly: he doesn't say "The economy is going to go bust." He says: his CAPE ratio for the markets (a 10-year average PE) has only been higher at 2 times in history: 1929 and 2000. And that was 2014. That's scary but you just can't predict the future. We could have a booming economy and stock market

The book gets its name and theme from the buzzwords used in Alan Greenspan's speech as the Chairman of the US Federal Reserve Board in 1996. It focuses on how the mood of 'irrational exuberance' is pushing up the stock prices and stretching the valuations and how the levels of the US Stock markets are way above rational. With thorough research and groundbreaking findings, Prof. Shiller convinces us about his theory of the unprecedented bubble. P/E ratios were dramatically out of line with ...more

It is a literature on the bubbles existing in the world of financial markets. Shiller takes us through the various bubbles that sustained themselves due to herd mentality and feedback mechanisms in the markets. The underlying message of the book is to question the efficient market hypothesis and to caution the investors against the soaring markets due to amplification effects. Apart from this key message, I found most of the content to be repetitive and redundant.

This book did not tell me a lot. Humans are irrational creatures. Our financial market shares in this irrationality, despite what experts want to tell us. Thus, we should try to hedge our bets as much as possible.

Predicting two major recessions, Shilling lays out his thoughts on the stock market - feeling very much like a systematic dismantle of the seemingly flimsy market that many in the world look up to as a marker for American status, wealth, and the direction of the country (and in some cases, the world). An excellent piece on financial psychology that predicted not one, but two different crashes.

An excellent inbetween book. Not too academic and dry but also not too simplistic. The most complete treatment of bubbles I've read.

Shiller is a great empiricist, and tests out efficient markets hypothesis through various econometric tests and survey data. Shiller actually asks investors through extensive survey data to see what their motivations and logic is, a pretty simple but radical move from assuming them to be rationally calculating agents. Through this data Shiller shows how irrational,

The third edition of Irrational Exuberance by Shiller analyses and explains the influence of structural, cultural, and psychological factors in the creation of bubbles. The book reads as the mix of an academic economic research paper and a popular non-fiction book, and contains an abundance of useful references to prior research.

Shiller does not shy away from expressing his own view throughout the book. This is particularly useful for the reader without an advanced economic background: the

Perhaps I’m giving him an extra star just for winning the Nobel Prize. Shiller is clearly a brilliant man and this book is well researched. However, I’m not sure we learn anything. We’ve known of booms and busts for a long time. This book is a discussion about the efficient market theory and why markets really aren’t efficient at all. I still hold to the theory myself, knowing that it is clearly wrong at times for all the reasons found in this book.

Irrational exuberance was a book I had been wanting to read for a very long time, so the question was: was the book worth the excitement I felt when the third edition was finally released? Well, yes and no. There are a few chapters that I thought were absolutely essential, namely the chapters in the first 100 pages of the book, including the introduction.

The second part, in which Shiller makes strange comparisons (I thought the epidemic-metaphor was not entirely appropriate), and discusses

This the most valuable book in my collection. Other books have a higher monetary value but this book has personal value. My copy is a first edition first imprint that was a birthday gift from my family. The book was bought from someone in Spain online, got temporarily lost in Argentina, came back to Spain, arrived in Australia.

Schiller's book is important for the weight that his name puts behind the case that investors need to understand the real risks involved in the assets that they buy and should eschew the comforting but simplistic conventional "wisdom" that claims that markets are always efficient, that "x always goes up" or "Y always outperforms a, b and c in the long run," and for the breadth of the research that he put into making the case. The book is also quite readable. I read it over the course of a few ...more

With Shiller sharing a lot of time in the news, I decided to read the book that made him famous.

The book is a great collection of information on how the assumption that investors are rational is false. He decimates the idea that individual investors make rational decisions through an exhaustive list of examples, backed by verifiable data.

The downside of the book, is in how it is written. The author makes use of references, and still decides to put the exact same information in the reference into

Shiller discusses the nature of “speculative bubble” and challenges the market efficiency. The first two parts are quite juicy. As a needy reader, I could always find something to chew on. The first part discusses the potential precipitating factors for the booming stock market such as the baby booming, the internet boom and the rise of gambling opportunities. After that, he says the feedback loop mechanism amplifies these factors. The second part, he states that it is the advent of “new era” ...more

Robert J. Shiller’s Irrational Exuberance challenges the conventional thinking on financial markets, especially the “efficient markets” theory. Shiller examines the role of media, the herd mentality, psychology, as well as so-called “new era” philosophy in shaping the beliefs and behavior of investors. Shiller does not claim that financial markets are completely random—there are certain patterns that can be predicted and utilized—but markets do not always reflect the correct price of an asset. ...more

I'll focus on what I see as the book's key strengths: clarity and long term perspective. As an investor it's difficult to recognize a bubble when you're in it, and the book provides context to understand where we are "in the larger scheme of things." I read Graham's Intelligent Investor just prior to reading this, and the this adds robust layers to Graham's focus on varying investment conditions and expected returns over the longer term. I guess the central theme is that asset classes will ...more

Full of many interesting ideas related to behavioral finance and economics (though if you've already read Animal Spirits, you will have seen several of the same already). After the introduction to this new edition, I was hoping for some more insight on bond markets specifically, but there was little to be had in the main text. There were also no particularly specific policy prescriptions for dealing with "irrational exuberance" in speculative markets, mostly just a general suggestion that the ...more

The first review I read before reading this book stated "Shiller clearly thinks he is the smartest man in the room, and he just might be right" is easily my first impression after having finished this book. His analysis of the psychology behind finance and economics is very interesting and thought provoking. His dismantling of the efficient market theory was thorough. Mostly easy to follow even though I have little technical background in economics. He began to loose me in the first pages of his ...more

“Irrational exuberance is the psychological basis of a speculative bubble. I define a speculative bubble as a situation in which news of price increases spurs investor enthusiasm, which spreads by psychological contagion from person to person, in the process amplifying stories that might justify the price increases and bringing in a larger and larger class of investors, who, despite doubts about the real value of an investment, are drawn to it partly through envy of others’ successes and partly through a gambler's excitement.” 6 likes
“Just what is a speculative bubble? The Oxford English Dictionary defines a bubble as “anything fragile, unsubstantial, empty, or worthless; a deceptive show. From 17th c. onwards often applied to delusive commercial or financial schemes.” The problem is that words like show and scheme suggest a deliberate creation, rather than a widespread social phenomenon that is not directed by any central impresario.” 3 likes
