The results show a remarkable constant scaling behaviour between different time … expressed through a scaling exponent, describing the development of the distributions as the time scale changes.

The most suitable paradigms and tools for investigating the scaling structure of financial time series are reviewed and … discussed in the light of some recent empirical results. Different types of scaling are distinguished and several definitions of … scaling exponents, scaling and multi-scaling processes are given. Methods to estimate such exponents from empirical financial …

We study dynamical behavior of the Chinese stock markets by investigating the statistical properties of daily ensemble return and variety defined, respectively, as the mean and the standard deviation of the ensemble daily price return of a portfolio of stocks traded in China's stock markets on a...

The author argues that it is microeconomics that needs foundations, not macroeconomics. Preferences need to be built on biology, and, in particular, on neuroscience. In contrast, macroeconomics could benefit from rationalizations of aggregate economic phenomena by non-equilibrium statistical...

I argue that it is microeconomics that needs foundations, not macroeconomics. Preferences need to be built on biology, and, in particular, on neuroscience. In contrast, macroeconomics could benefit from rationalizations of aggregate economic phenomena by non-equilibrium statistical physics.

The authors propose a new method for estimating the power-law exponents of firm size variables. Their focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. On the one hand, as is well known a firm size variable follows a power-law...
