Optimal Need-Based Financial Aid

2021 , Colas, Mark , Findeisen, Sebastian , Sachs, Dominik

We study the optimal design of student financial aid as a function of parental income. We derive optimal financial aid formulas in a general model. We estimate a model of selection into college for the United States that comprises multidimensional heterogeneity, endogenous parental transfers, dropout, labor supply in college, and uncertain returns. We quantify optimal financial aid in the estimated model and find it is strongly declining in parental income even without distributional concerns. Equity and efficiency go hand in hand.

The Indirect Fiscal Benefits of Low-Skilled Immigration

, Colas, Mark , Sachs, Dominik

Low-skilled immigrants indirectly affect public finances through their effect on resident wages & labor supply. We operationalize this indirect fiscal effect in a model of immigration and the labor market. We derive closed-form expressions for this effect in terms of estimable statistics. An empirical quantification for the U.S. reveals an indirect fiscal benefit for one average low-skilled immigrant of roughly $750 annually. The indirect fiscal benefit may outweigh the negative direct fiscal effect that has previously been documented. This challenges the perception of low-skilled immigration as a fiscal burden.
