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…
Instrument-Free Demand Estimation Using Relative Prices Variation, with an Application to Railway Transportation
Xavier D'Haultfœuille, Ao Wang, Philippe Février +1
We develop a new identification strategy for demand estimation when cost shifters may not be available and there are substantial variations in demand over time. This approaches rel…
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…
The Marcinkiewicz-Zygmund law of large numbers for exchangeable arrays
Laurent Davezies, Xavier D'Haultfoeuille, Yannick Guyonvarch
We show a Marcinkiewicz-Zygmund law of large numbers for jointly, dissociated exchangeable arrays, in () and almost surely. Then, we obtain a law of iterated loga…
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…
Empirical Process Results for Exchangeable Arrays
Laurent Davezies, Xavier D'Haultfoeuille, Yannick Guyonvarch
Exchangeable arrays are natural tools to model common forms of dependence between units of a sample. Jointly exchangeable arrays are well suited to dyadic data, where observed rand…
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…
