Local-Polynomial Estimation for Multivariate Regression Discontinuity Designs
Masayuki Sawada, Takuya Ishihara, Daisuke Kurisu +1
We study a multivariate regression discontinuity design in which treatment is assigned by crossing a boundary in the space of multiple running variables. We document that the exist…
Optimal estimation for regression discontinuity design with binary outcomes
Takuya Ishihara, Masayuki Sawada, Kohei Yata
We develop a finite-sample optimal estimator for regression discontinuity design when the outcomes are bounded, including binary outcomes as the leading case. Our estimator achieve…
A unified test for regression discontinuity designs
Koki Fusejima, Takuya Ishihara, Masayuki Sawada
Diagnostic tests for regression discontinuity design face a size-control problem. We document a massive over-rejection of the diagnostic restriction among empirical studies in the…
Manipulation-Robust Regression Discontinuity Designs
Takuya Ishihara, Masayuki Sawada
We present simple low-level conditions for identification in regression discontinuity designs using a potential outcome framework for the manipulation of the running variable. Usin…
