This paper investigates the nature and the presence of bubbles in financial markets. Are bubbles consistent with rationality? If they are, do they, like Ponzi games, require the presence of new players forever? Do they imply impossible events in finite time, such as negative prices? Do they need to go on forever to be rational? Can they have real effects? These are some of the questions asked in the first three sections. The general conclusion is that bubbles, in many markets, are consistent with rationality, that phenomena such as runaway asset prices and market crashes are consistent with rational bubbles. In the last two sections, we consider whether the presence of bubbles in a particular market can be detected statistically. The task is much easier if there are data on both prices and returns. In this case, as shown by Shiller and Singleton, the hypothesis of no bubble implies restrictions on their joint distribution and can be tested. In markets in which returns are difficult to observe, possibly because of a nonpecuniary component, such as gold, the task is more difficult. We consider the use of both "runs tests" and "tail tests" and conclude that they give circumstantial evidence at best.

This book makes two key contributions to empirical finance. First it provides a comprehensive analysis of the Thai stock market. Second it presents an excellent exposition ofhow modem econometric techniques can be utilised to understand a market. The increasing globalisation of the world's financial markets has made our un derstanding of the risk-return relationship in a broader range of markets critical. This is particularly so in emerging markets where market depth and liquidity are major issues. One such emerging market is Thailand. The Thai capital market isof particular interest given that it was the market in which the Asian financial crises commenced. As such an understanding ofthe Thai capital market via study of the pre and post-crisis periods enables one to shed light on one of the major financial markets events of recent times. This book provides a quantitative analysis of the Thai capital market using some very useful and recent econometric techniques. The book provides an over view of the Thai stock market in chapter 2. Descriptive statistics and time series models (moving average, exponential smoothing, ARIMA) are presented in chap ter 3 followed by market efficiency tests based on autocorrelations in chapter 4. A richer set of models is then considered in chapters 5 through 8. Chapter 5 finds a cointegrating relationship between macroeconomic factors and stock returns.

“This book provides an accessible, yet formal framework to understand how housing bubbles arise, their international dimension, their consequences, and ways to prevent them.” Òscar Jordà, University of California, Davis, USA “Basco’s analysis blends, in a very rigorous but enjoyable manner , state-of-the-art theory and historical examples, adding also a very timely and valuable set of policy orientations.” Óscar Arce, Director General, Banco de España, Madrid, Spain Booms and busts of house prices are a recurrent feature throughout history. This book provides a comprehensive overview of the origins and economic consequences of these housing bubbles. The book starts with a formal definition of asset price bubbles and a summary of the most famous episodes, before describing how economists have thought about asset price bubbles; specifically behavioral vs. rational interpretations. These theories are applied to the special case of housing and the same framework is used to explain the implications of financial globalization for capital flows and housing bubbles. After analyzing its origins, the economic consequences of housing bubbles for both households and firms are derived and documented. The final sections are devoted to discussing the effects of financial crises and explain how financial regulation could mitigate the emergence of future housing bubbles. Case studies of the recent housing bubbles in the United States and Spain are also featured in the book. This book will be of value to advanced undergraduate macroeconomic courses, as well as researchers in international economics and macroeconomics and policy makers.

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.

It is well known that rational bubbles can be sustained in a dynamically inefficient economy, where the return to capital r is below the growth rate g. However, empirical evidence suggests that modern economies are most of the time on an efficient path with r>g. This paper shows that rational bubbles can be sustained when rg for some episodes only. Bubbly assets are shown to enhance efficiency, although they do not allow the implementation of first-best. Where r
