Social and psychological issues associated with the new genetics

Socio-economic determinants for the portuguese immigration : an empirical discussion
This paper explores the determinants of immigration to Portugal. It is the first study to empirically evaluate an extended set of determinants to explain this new phenomenon in Portugal, a highly globalized economy and a 40-year-old democracy. This study finds evidence that the use of Portuguese as the mother tongue and prior Portuguese immigration are the main determinants of current immigration to Portugal from a given country. Depending on which subgroup is considered (refugees, students, or workers), more specific findings also arise. For refugees and foreign workers, human rights violations help explain increased immigration; for foreign students, low per capita income (in the home country) is a significant factor. Dividing the sample into Portuguese speakers and non-Portuguese speakers, we also identified the level of economic development as an important determinant for immigrants from non-lusophone countries. The military situations of the home countries were also important determinants for lusophone immigrants.COMPETE; QREN; FEDE
