Drivers of brain drain phenomenon: possible association between macroeconomic variables in the international framework.

Brain drain phenomenon has reached a high level of importance in current socio-economic context also for policy choices related; for this reason, the aim of this survey is to provide a general framework, overcoming traditional “mediatic” approach, trying to achieve a description of its nature and the main variables that could affect it. After a brief presentation of the most important contributions in literature, in order to reach a theoretical framework, this paper shows a primary description of brain drain trends and directrices. According with Beltrame (2007) and his approach, there was a general absence of homogeneity between various scientific disciplines involved on studied phenomenon. For this reason, it seems appropriate to make a primary research and description of brain drain drivers trying to highlight similarities between different host countries; one of the most important aspects that is related to the analysis of brain drain perception and its causes with associated policy implication. For what has been said, research question implies the existence of a relationship between main social-economic variables and skilled mobility. Starting from this feedback the purpose of this work is to outline this association and the reasons attributable to such evidence.
