The Economic Logic blog has posted on an interesting new study by Vincenzo Caponi which finds that third generation Mexican immigrants (particularly males)to the US earn significantly lower wages than second generation Mexican immigrants.
The table below shows the evolutions of earnings across all generations. It reports results for men and women using two definitions: the standard definition and the stricter definition. The standard definition includes those with at least one parent born in Mexico while the stricter definition includes those who not only have at least one parent born in Mexico, but also consider themselves Mexican.
Economic Logic concludes the following:
The way I understand it is that there is selection in migration decisions: only those with higher than average abilities (not necessarily realized human capital) go. Their children inherit some of those traits, and thus have higher than average abilities and human capital. While the first generation was not able to fully exploit this, while the second does, wages go up. But abilities of the third generation continue regressing to the mean, and the selection effect erodes. This generation ends up with lower human capital than their parents and thus lower wages.
