Research Achievements

RDDs and electoral data

In joint work, Jasjeet Sekhon (IGERT faculty affiliate) and Devin Caughey (IGERT trainee) have demonstrated that the "smoothness" assumption required for regression-discontinuity designs (RDDs) is not valid for U.S. elections due to the non-random fashion in which very close elections are decided. This finding suggests that when applied to electoral data, RDDs should not be interpreted as a natural experiment but rather as something more akin to an observational study.
