Opis: Econophysics and Physical Economics - Stefan Hutzler, Jurgen Mimkes, Peter Richmond

An understanding of the behaviour of financial assets and the evolution of economies has never been as important as today. This book looks at these complex systems from the perspective of the physicist. So called 'econophysics' and its application to finance has made great strides in recent years. Less emphasis has been placed on the broader subject of macroeconomics and many economics students are still taught traditional neo-classical economics. The reader is given a general primer in statistical physics, probability theory, and use of correlation functions. Much of the mathematics that is developed is frequently no longer included in undergraduate physics courses. The statistical physics of Boltzmann and Gibbs is one of the oldest disciplines within physics and it can be argued that it was first applied to ensembles of molecules as opposed to being applied to social agents only by way of historical accident. The authors argue by analogy that the theory can be applied directly to economic systems comprising assemblies of interacting agents. The necessary tools and mathematics are developed in a clear and concise manner. The body of work, now termed econophysics, is then developed. The authors show where traditional methods break down and show how the probability distributions and correlation functions can be properly understood using high frequency data. Recent work by the physics community on risk and market crashes are discussed together with new work on betting markets as well as studies of speculative peaks that occur in housing markets. The second half of the book continues the empirical approach showing how by analogy with thermodynamics, a self-consistent attack can be made on macroeconomics. This leads naturally to economic production functions being equated to entropy functions - a new concept for economists. Issues relating to non-equilibrium naturally arise during the development and application of this approach to economics. These are discussed in the context of superstatistics and adiabatic processes. As a result it does seem ultimately possible to reconcile the approach with non-equilibrium systems, and the ideas are applied to study income and wealth distributions, which with their power law distribution functions have puzzled many researchers ever since Pareto discovered them over 100 years ago. This book takes a pedagogical approach to these topics and is aimed at final year undergraduate and beginning gradaute or post-graduate students in physics, economics, and business. However, the experienced researcher and quant should also find much of interest. "The authors present a novel approach to modern economic theory informed by empirical observations and ideas from physics, and in particular complex systems. Comprehensive in scope, and written in an engaging style, the text will be essential reading for students and researchers in the field." - Geoff J. Rodgers, Brunel University "Adapting physics to understand economical problems may help us to develop new financial models. Science can help to change the world, not merely interpret it." - Ian Gibson, MP Norwich North, 1997-2009, Chair of House of Commons Science and Technology Committee 2001-2005, School of Biological Sciences, University of East Anglia 1965 - 1997 "This book is the result of a unique joint effort by three very complementary authors. The result of their cooperation is a down to earth and practical text which, at the same time, offers a mathematically sound exposition of how ideas based in physics help our understanding of finance and economic dynamics. It is a significant contribution to the task of introducing new scientific methods, concepts and ideas to the study of economies." - Sorin Solomon, Racah Institute of Physics, Hebrew University of Jerusalem "This book discusses intriguing analogies between physical and economical phenomena. In fact, methodologies borrowed from physics were crucial for the development of economical models in the past, e.g. non-equilibrium statistical physics opened the gate for the financial derivative pricing. The book may catalyze a broader discussion among economists and physicists about roots of the current economical crisis and ways the global economy should be stabilized." - Janusz Ho?yst, Warsaw University of Technology, Poland1.
