Difference-in-Differences Estimators When No Unit Remains Untreated
Clément de Chaisemartin, Diego Ciccia, Xavier D'Haultfœuille +1
We study difference-in-differences designs in which all units are initially untreated and later receive heterogeneous, strictly positive treatment doses. When quasi-untreated units…
A Robust Permutation Test for Subvector Inference in Linear Regressions
Xavier D'Haultfœuille, Purevdorj Tuvaandorj
We develop a new permutation test for inference on a subvector of coefficients in linear models. The test is exact when the regressors and the error terms are independent. Then, we…
Nonparametric Difference-in-Differences in Repeated Cross-Sections with Continuous Treatments
Xavier D'Haultfoeuille, Stefan Hoderlein, Yuya Sasaki
This paper studies the identification of causal effects of a continuous treatment using a new difference-in-difference strategy. Our approach allows for endogeneity of the treatmen…
Fixed Effects Binary Choice Models with Three or More Periods
Laurent Davezies, Xavier D'Haultfoeuille, Martin Mugnier
We consider fixed effects binary choice models with a fixed number of periods and regressors without a large support. If the time-varying unobserved terms are i.i.d. with known…
Two-way fixed effects estimators with heterogeneous treatment effects
Clément de Chaisemartin, Xavier D'Haultfœuille
Linear regressions with period and group fixed effects are widely used to estimate treatment effects. We show that they estimate weighted sums of the average treatment effects (ATE…
