%0 Report %A Leopold, Stefan %A Ruhose, Jens %A Wiederhold, Simon %T Why Is the Roy-Borjas Model Unable to Predict International Migrant Selection on Education? Evidence from Urban and Rural Mexico %D 2023 %8 2023 Jul %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 16339 %U https://www.iza.org/publications/dp16339 %X The Roy-Borjas model predicts that international migrants are less educated than nonmigrants because the returns to education are generally higher in developing (migrant-sending) than in developed (migrant-receiving) countries. However, empirical evidence often shows the opposite. Using the case of Mexico-U.S. migration, we show that this inconsistency between predictions and empirical evidence can be resolved when the human capital of migrants is assessed using a two-dimensional measure of occupational skills rather than by educational attainment. Thus, focusing on a single skill dimension when investigating migrant selection can lead to misleading conclusions about the underlying economic incentives and behavioral models of migration. %K international migration %K selection %K occupational skills %K education
