This presentation will provide an introduction to Regression Discontinuity Designs (RDDs), one of the most credible identification strategies for policy evaluation. We then present a new method for extrapolation in RDDs that relies on the presence of multiple cutoffs. Our approach is based on an easy-to-interpret identifying assumption that mimics the idea of “common trends” in difference-in-differences designs. We use our methods to study the effect of ACCES, a subsidized loan program for higher education in Colombia, and offer new empirical evidence on the program effects for students with test scores away from the cutoff that determined program eligibility.
