Paradoxically, countries with smaller diasporas show higher levels of migration selectivity. It is estimated that about 40% of these skilled, in most cases professional immigrants not find employment in their chosen profession (scientific and engineering) and they are under-utilized and their talent and skills are wasted.
Finally, although the impacts of globalization are difficult to assess, we find that countries with continued and consistent economic and educational policies have smaller stocks of high skilled population living abroad than others (this is the cases of Brazil and Chile). Therefore, despite the limitations imposed by the global situation, it is possible to act at national level to guide the human resources for the development of the country. This point of view permit thinks two kinds of policies: 1) a regional policy of human resources coherent with Latin American labor market demand; 2) a national policy oriented to the institutionalization of the diaspora and knowledge exchange mechanisms between the diaspora and the professionals working in the country of origin
