Typesetting: Camera-ready by authors and the editor SPIN: 10838138 Preface The environment surrounding world financial markets is changing drastically. Fluctuations are now so complex that they are beyond the scope of conventional economic theories and could potentially disrupt the world economy. Currency exchange has been liberalized, round-the-clock trading through computer networks is brisk, and financial derivative products are becoming more complicated and diverse. To avoid the disorder resulting from financial fluctuations, problems should be dealt with not on an individual, profit-seeking basis, but jointly. It is imperative that economists collectively analyze data on current financial and monetary activities using the most sophisticated scientific instruments and engage in extensive discussions of the results. That was the aim of the international workshop "Empirical Science of Financial Fluctuations," organized by the Nihon Keizai Shimbun in Tokyo, November 15- 17, 2000. Attended by more than 60 researchers from 17 countries, the workshop represented a melting pot of physicists, information scientists, economists, and financial practitioners seeking to establish empirical facts regarding financial fluctuations. These proceedings give numerous examples of empirical findings based on actual data from financial markets, together with basic theoretical and computational approaches. The workshop was supported by: the Bank of Japan; the Financial Markets Department, Economic Planning Agency, Government of Japan; the Economic Research Institute; the Japan Center for Economic Research; the Physical Society of Japan; and the Japan Association for Evolutionary Economics. On behalf of all participants, I would like to thank those supporters, as well as the following companies without whose financial support the workshop would not have been possible: Osaka Securities Exchange; Canon, Inc.; Sony Corporation; Information Service International-Dentsu, Ltd.; Dresdner Kleinwort Benson Limited; and Mitsui and Co., Ltd. As the chief organizer, I am grateful for the cooperation of the organizers T. Shimizu (Bank of Japan), J. Uno (OptiMark Systems, Inc.), and H.E. Stanley (Boston University). I would also like to thank keynote speakers H.E. Stanley, R.N. Mantegna, J.D. Farmer, Y.-C. Zhang, and M. Ausloos. Special appreciation is extended to the members of the conference secretariat, as represented by K. Kamohara, for their kind efficiency and to the staff of Springer-Verlag, Tokyo, for editorial support. Finally, I would like to thank all the authors for their contributions to this volume. H.

This manuscript is a brief summary of a talk that was designed to address the question of whether two of the pillars of the field of phase transitions and critical phenomena-scale inv ariance and universality--can be useful in guiding research on interpreting empirical data on economic fluctuations. In particular, we shall develop a heuristic argument that serves to make more plausible the scaling and universality hypotheses. 1 Introduction Empirical evidence has been mounting that supports the intriguing possibility that a number of systems arising in disciplines as diverse as physics, biology, ecology, and economics may have certain quantitative features that are in triguingly similar. These properties can be conveniently grouped under the headings of scale invariance and universality. By scale invariance is meant a hierarchical organization that results in power-law behavior over a wide range of values of some control parameter-such as species size, heartbeat interval, or firm size-and the exponent of this power law is a number characteriz ing the system. By universality is meant a tendency for the set of exponents found for diverse systems to partition themselves into distinct "universality classes," with the property that all systems falling into the same universality class have the same exponent-suggesting that there are features in common among the underlying microscopic mechanisms responsible for the observed scale invariant behavior. Researchers have found new and surprising results by applying concepts and methods of scale invariance and universality to the economy. The econ omy is perhaps the most complex of all complex systems. A very small piece of "bad news" in a remote market may trigger a very large response in financial indices all over the globe. The societal impact of such economic fluctuations can be devastating. Privately, economists will confirm that the probability of such an "economic earthquake" is not entirely negligible-that a sudden and disastrous "phase transition" could occur from the present healthy state H.

Description:
Financial fluctuations were generally neglected in classical ecnomics and their basic statistical properties have only recently been elucidated in the emerging field of econophysics, a new science that analyzes data using methods developed by statistical physics, such as chaos, fractals, and phase t
