Las características educativas de los emigrantes mexicanos a Estados Unidos

this paper studies the self selection in educational characteristics of mexicans migrating to the us. this is done to determine educational self-selection, changes in self-selection in the nineties, as well as the change in the self-selection in terms of the wage distribution. the paper applies econometric techniques that control for bias by the use of endogenous samples. there are four key findings: first, self selection in the nineties was intermediate; second, self selection in 2000 was in the extremes of the education distribution: at zero years and at more than 16 years of education; third, the largest changes in migration probability were experienced by those two groups; and fourth, despite the changes in migration probabilities, the change in self selection in terms of the wage distribution is a change towards intermediate selection.
