Econophysics: Comments on a Few Applications, Successes, Methods and Models

Abstract

For this special issue, the article aims at discussing a few econophysics problems studied so far rather successfully. The following ‘applications’ in micro-econophysics are considered: (i) financial crashes; it is emphasized that one can distinguish between endogenous and exogenous causes; (ii) portofolio control, selection and inherent risk measure; (iii) foreign currency exchanges, also distinguishing endogenous and exogenous money control; (iv) price and asset evolution values. It is shown that some macro-econo-physics problems have been also tackled, like geographic/ political constraints, the globalization of the economy and country clustering. Moreover, it is daring to suggest prospect for studies and researches, whence presenting some selection of a few interesting perspectives.
