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.

This paper analyzes the impact of reduced tax incentives for equity financing on banks' regulatory capital ratios under the Basel III regime. We are particularly interested in a recent interest rate cut in the Italian corporate equity allowance, which reduces the relative tax advantage of equity financing. The results show that banks respond to this increased tax disparity by significantly reducing their regulatory capital while at the same time reducing their risk-taking. The decline in capital is more pronounced for small banks and outweighs the initial capital gains from the introduction of this tax instrument. Our results challenge the use of equity allowances, in that financial stability gains persist only as long as costly tax subsidies remain intact and diminish as the size of the subsidy is reduced.

This paper uses a new empirical design to explore how labor market polarization affects individuals’ incentive to pursue education funded on the margin by student debt. We argue that the labor market polarization–where automation replaces mid-skill and mid-education-level job–changes the marginal benefits of education and training and sharpens incentives to incur student debt. We advance a new measure of labor market polarizations that allows to capture the heterogeneity of this phenomena across geographies and time. Using this measure, we find that U.S. CBSAs that experience deeper labor market polarization see an increase in student debt balances and in the number of people pursuing student debt. On average, the decline in middle-skill jobs and wages has little effect on individuals’ ability to pay down existing student debt. The effects are most pronounced in ZIP codes with lower average credit scores, lower incomes, and higher share of the minority population.
