In this paper, we compare the results from a randomized clinical trial to
the results from a regression discontinuity quasi-experiment when both designs are
implemented in the same setting. We find that the results from the two approaches
are effectively identical. We attribute the comparability in part to recent statistical
developments that make the model required for the analysis of data from a regression
discontinuity design easier to determine. These developments make an already
strong quasi-experimental design even stronger. (Authors’ abstract).
