摘要:The number of hypothesis trying to explain which are the reasons behind the decision to migrate into a developed country are diverse and difficult to test due to the multiplicity of factors which affect it.This paper shows empirical evidence about the determinants of the migratory flows to 21 OECD countries in the 1980-2000 period. Our results reveal the importance to differentiate the inflows composition by at least income in the origin countries.Thus, regarding inflows from non-high-income countries, the results suggest that there is a pull effect from monetary and not real income, and then, the welfare magnets hypothesis should be rejected.
