Introduction to Econophysics: Correlations and Complexity in FinanceStatistical physics concepts such as stochastic dynamics, short and long range correlations, self similarity and scaling, permit an understanding of the global behavior of economic systems without first having to work out a detailed microscopic description of the system. This pioneering text explores the use of these concepts in the description of financial systems, the dynamic new specialty of econophysics. The authors illustrate the scaling concepts
