Exploiting Discovered Regression Discontinuities to Debias Conditioned-on-observable Estimators

Regression discontinuity (RD) designs are widely used to estimate causal effects in the absence of a randomized experiment. However, standard approaches to RD analysis face two significant limitations. First, they require a priori knowledge of discontinuities in treatment. Second, they yield doubly-local treatment effect estimates, and fail to provide more general causal effect estimates away from the discontinuity. To address these limitations, we introduce a novel method for automatically detecting RDs at scale, integrating information from multiple discovered discontinuities with …
