We study the labor market returns to a State Guaranteed Loan used to finance university degrees in Chile. Using a regression dis- continuity design, we show that marginally eligible students forgo vocational education in favor of university education but reduce their probability of graduation. Even though university loan takers accumulate more student debt, their labor market outcomes are not different from those of ineligible students. We find suggestive evidence that the lower quality of the receiving institutions accounts for these results. Finally, we extrapolate the effects away from the eligibility cutoff and show that supramarginal students benefit from this policy.
