This paper studies whether higher education causes economic development. The identification strategy combines India's large-scale liberalization of higher education with spatial variation in college expansion generated by affiliation requirements and the pre-determined location of public universities. The empirical estimates show that a one-percentage-point increase in the share of college graduates over a decade reduces agricultural employment by 0.8 percentage points while increasing services employment by 0.9 percentage points, real GDP per worker by 2.3 percent, and nightlight intensity by 6.2 percent. These results are consistent across instrumental variable, event study, and border discontinuity designs. The estimates imply that social returns to human capital are 30 percent larger than private returns. The reduced-form estimates are then used to calibrate a spatial general equilibrium model with endogenous education choices and human capital externalities. The model implies that for the average district, India's higher education reform accounts for 20 percent of output growth between 2001 and 2011. Counterfactual simulations show that removing spatial barriers to college opening would have increased the average district's 2011 output by 3 percent. These findings demonstrate that higher education expansion is a powerful driver of economic development and modernization.
