Estimating Treatment Effects Under Bounded Heterogeneity
Soonwoo Kwon, Liyang Sun
Specifications that impose constant treatment effects are common but biased, while fully flexible alternatives can be imprecise or infeasible. Under a bound on treatment effect het…
Empirical Bayes shrinkage (mostly) does not correct the measurement error in regression
Jiafeng Chen, Jiaying Gu, Soonwoo Kwon
In the value-added literature, it is often claimed that regressing on empirical Bayes shrinkage estimates corrects for the measurement error problem in linear regression. We clarif…
Testing Mechanisms
Soonwoo Kwon, Jonathan Roth
Economists are often interested in the mechanisms by which a treatment affects an outcome. We develop tests for the "sharp null of full mediation" that a treatment affects an o…
Extrapolation in Regression Discontinuity Design Using Comonotonicity
Ben Deaner, Soonwoo Kwon
We present a novel approach for extrapolating causal effects away from the margin between treatment and non-treatment in sharp regression discontinuity designs with multiple covari…
