Macrostate Parameter, an Econophysics Approach for the Risk Analysis of the Stock Exchange Market Transactions


  • Anca Gheorghiu
  • Ion Spanulescu


In this paper we attempt to introduce an econophysics approach to evaluate some aspects of the risks in financial markets. For this purpose, the thermodynamical methods and statistical physics results about entropy and equilibrium states in the physical systems are used. Some considerations on economic value and financial information are made. Finally, on this basis, a new index for the financial risk estimation of the stock-exchange market transactions, named macrostate parameter, was introduced and discussed. Keywords: econophysics, stock-exchange markets, financial risk, informational fascicle, entropy, macrostate parameter.
