The main objective of this 2002 book is to show that behind the bewildering diversity of historical speculative episodes it is possible to find hidden regularities, thus preparing the way for a unified theory of market speculation. Speculative bubbles require the study of various episodes in order for a comparative perspective to be obtained and the analysis developed in this book follows a few simple but unconventional ideas. Investors are assumed to exhibit the same basic behavior during speculative episodes whether they trade stocks, real estate, or postage stamps. The author demonstrates how some of the basic concepts of dynamical system theory, such as the notions of impulse response, reaction times and frequency analysis, play an instrumental role in describing and predicting speculative behavior. This book will serve as a useful introduction for students of econophysics, and readers with a general interest in economics as seen from the perspective of physics.

• Provides useful insights into the ordered patterns that lie behind market speculation • Written at a level that is comprehensible to both physicists and economists • Bridges the gap between physics and the social sciences

'I shall not attempt to summarise here Roehner's proposal for a theoretical framework that would recognise a pattern in speculative bubble situations. Professionally involved readers, for whom this book is a must-read, can enjoy discovering it for themselves as much as I did.' Rudi Bogni, The Times Higher Education Supplement

'… a rewarding and worthwhile read. As an introduction to the subject it has much to offer on the way complex problems, not just in economics or econophysics, should be addressed.' R. Toumi and P. S. Wilson, Contemporary Physics
