Migration introduces asymmetries of information that might trigger noncooperative behavior of spouses left behind. This paper studies noncooperative behavior in Mexican households and how this behavior affects children’s human capital. I use the Mexican Family Life Survey (MXFLS), a longitudinal household survey that identifies migrants to the U.S. I find that migration causes noncooperative behavior in the spouse left behind, namely spouses reduce the time in doing chores and do not change their labor supply. At the same time, boys do more agricultural work and girls have to spend more time in taking care of other members. Migration positively affects school enrollment, but nonlinear effects suggest younger children are bearing most of the negative effect, as literature suggests lower school enrollment at early ages means lower cognitive achievement later on.
