 Empirical Tests of the Validity of the Regression Discontinuity Design: Implications for its Theory and its Use in Research PracticeThomas D. Cook and Vivian C. Wong Annals of Economics and Statistics, 2008, issue 91-92, 127-150 Abstract: This paper reviews the literature on whether regression-discontinuity studies reproduce the results of randomized experiments conducted on the same topic. After briefly reviewing the regression-discontinuity design and its history, we explicate the general conditions necessary for a strong test of correspondence in results when an experiment is used to validate any non-experimental method. In economics, within-study comparisons of this kind are associated with LaLonde [1986], and we elaborate on how to do such studies better than twenty years ago. We identify three cases where regression discontinuity and experimental results with overlapping samples were explicitly contrasted. By criteria of both effect sizes and statistical significance patterns, we then show that each study produced similar results across the experiment and regression-discontinuity study. This correspondence is what theory predicts. But to achieve it in the complex social settings in which these within-study comparisons were carried out suggests that regression-discontinuity results may be generally robust.
