Misurare il Brain Drain: missione possible? Rassegna dei principali contributi demo-economici sulla quantificazione e modellizzazione dei flussi migratori qualificati.

The aim of this paper is to provide an overview of the major empirical relevancies on the brain drain phenomena. The researches by Carrington and Detragiache (1998), Adams (2003), Dumont and Lemaitre (2003), Docquier and Rapoport (2005), Defoort (2008) and Docquier, Lowell and Marfouk (2009). have been particularly useful to establish a methodology to quantify the brain drain in terms of outflows from Developing countries and inflows into Developed countries. However, on a preliminary basis, it may be noted that the lack of reliable data as well as the absence of a harmonic definition - at an international level - on “qualified migrants", makes it difficult modeling and analyzing this particular type of international mobility.
