	abstract={Formal education is widely thought to be a major determinant of individual earnings. This paper uses the American Community Survey to examine the effect of formal schooling on worker wages. Given the potential endogeneity of education decisions, I instrument for individual schooling using cohort-level mean maternal years of schooling from previous decennial censuses. The instrumental variables results suggest that schooling has a significant positive effect on worker wages. Specifically, an additional year or schooling is estimated to increase hourly wages by 10 percent for men and 12.6 percent for women.},
