Synopsis :
Some economic phenomena are predictable and controllable, and some are impos- sible to foresee. Existing economic theories do not provide satisfactory answers as to what degree economic phenomena can be predicted and controlled, and in what situations. Against this background, people working on the financial front lines in real life have to rely on empirical rules based on experiments that often lack a solid foundation. "Econophysics" is a new science that analyzes economic phenomena empirically from a physical point of view, and it is being studied mainly to offer scientific, objective and significant answers to such problems. This book is the proceedings of the third Nikkei symposium on ''Practical Fruits of Econophysics," held in Tokyo, November 9-11, 2004. In the first symposium held in 2000, empirical rules were established by analyzing high-frequency finan- cial data, and various kinds of theoretical approaches were confimied. In the second symposium, in 2002, the predictability of imperfections and of economic fluctua- tions was discussed in detail, and methods for applying such studies were reported. The third symposium gave an overview of practical developments that can immedi- ately be applied to the financial sector, or at least provide hints as to how to use the methodology.
Présentation de l'éditeur:
The proceedings of the Third Nikkei Econophysics Symposium, "Business Models in the 21st Century - Risk Management and Expectations for Econophysics", held in Tokyo in November 2004, are gathered herein. Cutting-edge research on the practical application of econophysics is included, covering such topics as the predictability of markets, the analysis of rare events, the mechanism of crashes and bubbles, markets? correlation and risk management, investment strategy, stochastic market simulations, agent-based market simulations, wealth distribution, and network structures in economics, most of which are beyond the scope of standard financial technology. New market models and financial-data analysis methods are introduced, and dynamic aspects of markets and economy are highlighted. Professionals, researchers, and students will find an invaluable resource in this first book of its kind to summarize the latest work in the field of econophysics.
