Abstract. In this paper, we use data from the Mexico and U.S. population censuses to examine who migrates from Mexico to the United States and how the skills and economic performance of these individuals compare to those who remain in Mexico. We test Borjas' negative-selection hypothesis that in poor countries the individuals with the strongest incentive to migrate to rich countries are those with relatively low skill levels. We find that 1) Mexican immigrants, while much less educated than U.S. natives, are on average more educated than residents of Mexico, and 2) were Mexican immigrants in the United States to be paid according to current skill prices in Mexico they would tend to occupy the middle and upper portions of Mexico's wage distribution. These results are inconsistent with the negative-selection hypothesis and suggest, instead, that in terms of observable skills there is intermediate or positive selection of immigrants from Mexico. The results also suggest that migration abroad may raise wage inequality in Mexico.

Abstract This paper studies the effects of remittances from the U.S. on child labor and school attendance in recipient Mexican households. We identify these effects using the impact of the 2008-2009 U.S. recession on remittance receipts. The methodology employed is a differencesin-differences strategy that compares households that were remittance recipients before the crisis with never-recipient households. To avoid possible selection problems, we instrument for membership in the remittance recipient group. We find that the negative shock on remittance receipts caused a significant increase in child labor and a significant reduction of school attendance.

Terms of use: Documents in ResumenEn este documento se analizan los efectos de las remesas que los hogares mexicanos reciben de Estados Unidos sobre el trabajo infantil y la asistencia escolar. Para la identificación de estos efectos se utiliza el impacto de la recesión estadounidense de 2008-2009 sobre las remesas recibidas. Se emplea una metodología de diferencias-en-diferencias que compara hogares que recibían remesas antes de la crisis con hogares no receptores. Para evitar posibles problemas de selección, se instrumenta la variable de pertenencia al grupo receptor de remesas. Los resultados indican que el choque negativo sobre las remesas causó un incremento significativo del trabajo infantil y una reducción significativa de la asistencia escolar. Palabras Clave: Trabajo infantil, Migración internacional, Remesas, México.

In this paper, I study what factors determined the changes in Mexico's regional wage differentials during the nineties. I exploit the regional variation in exposure to international markets to identify the effects of NAFTA on wages and the skill premium. The results support the presence of Stolper-Samuelson type of responses during Mexico's trade liberalization: regions more exposed to globalization appear to have exhibited an increase in overall wage levels, but a decrease in the skill premium, relative to other regions of the country. The results suggest that trade liberalization has a spatial dimension that is usually neglected in traditional models.
