The presence of speculative bubbles in capital markets (an important area of interest in financial history) is widely accepted across many circles. Talk of them is pervasive in the media and especially in the popular financial press. Bubbles are thought to be found primarily in the stock market, which is our main interest, although bubbles are said to occur in other markets. Bubbles go hand in hand with the notion that markets can be irrational. The academic community has a great interest in bubbles, and it has produced scholarly literature that is voluminous. For some economists, doing bubble research is like joining the vanguard of a Kuhnian paradigm shift in economic thinking. Not so fast. If bubbles did exist, they would pose a serious challenge to neoclassical finance. Bubbles would contradict the ideas that markets are rational or work in an informationally efficient manner. That’s what makes the topic of bubbles interesting. This book reviews and evaluates the academic literature as well as some popular investment books on the possible existence of speculative bubbles in the stock market. The main question is whether there is convincing empirical evidence that bubbles exist. A second question is whether the theoretical concepts that have been advanced for bubbles make them plausible. The reader will discover that I am skeptical that bubbles actually exist. But I do not think I or anyone else will ever be able to conclusively prove that there has never been a bubble. From studying the literature and from reading history, I find that many famous purported bubbles reflect inaccurate history or mistakes in analysis or simply cannot be shown to have existed. In other instances, bubbles might have existed. But in each of those cases, there are credible rational explanations. And good evidence exists for the idea that even if bubbles do exist, they are not of great importance to understanding the stock market.

As long as there have been financial markets, there have been bubbles—those moments in which asset prices inflate far beyond their intrinsic value, often with ruinous results. Yet economists are slow to agree on the underlying forces behind these events. In this book José A. Scheinkman offers new insight into the mystery of bubbles. Noting some general characteristics of bubbles—such as the rise in trading volume and the coincidence between increases in supply and bubble implosions—Scheinkman offers a model, based on differences in beliefs among investors, that explains these observations. Other top economists also offer their own thoughts on the issue: Sanford J. Grossman and Patrick Bolton expand on Scheinkman's discussion by looking at factors that contribute to bubbles—such as excessive leverage, overconfidence, mania, and panic in speculative markets—and Kenneth J. Arrow and Joseph E. Stiglitz contextualize Scheinkman's findings.

Providing a comprehensive look at the most dramatic run-up in equity values in US history, this volume takes the reader from theory to empirics, illustrating why we need to go beyond the efficient markets hypothesis and the theory of domestic irrational exuberance to fully unpack the unprecedented phenomenon, why the market was destined for a major decline and why the fallout will be severe and protracted.

In distilling a vast literature spanning the rational— irrational divide, this paper offers reflections on why asset bubbles continue to threaten economic stability despite financial markets becoming more informationally-efficient, more complete, and more heavily influenced by sophisticated (i.e. presumably rational) institutional investors. Candidate explanations for bubble persistence—such as limits to learning, frictional limits to arbitrage, and behavioral errors—seem unsatisfactory as they are inconsistent with the aforementioned trends impacting global capital markets. In lieu of the short-term nature of the asset owner—manager relationship, and the momentum bias inherent in financial benchmarks, I argue that the business risk of asset managers acts as strong motivation for institutional herding and ‘rational bubble-riding.’ Two key policy implications follow. First, procyclicality could intensify as institutional assets under management continue to grow. Second, remedial policies should extend beyond the standard suite of macroprudential and monetary measures to include time-invariant policies targeted at the cause (not just symptom) of the problem. Prominent among these should be reforms addressing principal-agent contract design and the implementation of financial benchmarks.

This book describes a laboratory experiment designed to test the causes and properties of bubbles in financial markets and explores the question whether it is possible to design markets which avoid such bubbles and crashes. In the experiment, subjects were given the opportunity to trade in a stock market modeled after the seminal work of Smith et al. (1988). To account for the increasing importance of online betting sites, subjects were also allowed to trade in a digital option market. The outcomes shed new light on how subjects form and update their expectations, placing special emphasis on the bounded rationality of investors. Various analytical bubble measures found in the literature are collected, calculated, classified and presented for the first time. The very interesting new bubble measures "Dispersion Ratio", "Overpriced Transactions" and "Underpriced Transactions" are developed, making the book an important step towards the research goal of preventing bubbles and crashes in financial markets.

Gerald P. Dwyer, Jr. and R. W. Hafer The articles and commentaries included in this volume were presented at the Federal Reserve Bank of St. Louis' thirteenth annual economic policy conference, held on October 21-22, 1988. The conference focused on the behavior of asset market prices, a topic of increasing interest to both the popular press and to academic journals as the bull market of the 1980s continued. The events that transpired during October, 1987, both in the United States and abroad, provide an informative setting to test alter native theories. In assembling the papers presented during this conference, we asked the authors to explore the issue of asset pricing and financial market behavior from several vantages. Was the crash evidence of the bursting of a speculative bubble? Do we know enough about the work ings of asset markets to hazard an intelligent guess why they dropped so dramatically in such a brief time? Do we know enough to propose regulatory changes that will prevent any such occurrence in the future, or do we want to even if we can? We think that the articles and commentaries contained in this volume provide significant insight to inform and to answer such questions. The article by Behzad Diba surveys existing theoretical and empirical research on rational bubbles in asset prices.

This comprehensive, lucidly written text is an ideal introduction to behavioural finance. The book caters to the needs of both undergraduate and postgraduate management courses. It covers almost all important topics of behavioural finance prescribed in the syllabi of various universities across India, including Neurofinance and Forensic Accounting, which have rare occurrence in other books but are important from future perspective. There is a dearth of literature in behavioural finance, and if available, then the books are of large volumes, written by foreign authors citing examples and case studies from the countries other than India. Hence, the present book aims at providing information in global scenario, particularly Indian cases. A number of case studies and box items make this text interesting and informative. Review questions given at the end of each chapter help students in assessing their knowledge after having learned the concepts. Overall, the book will help readers in gaining adequate knowledge of the subject.
