Asymptotic Properties of Empirical Quantile-Based Estimators

Julien Chhor, Xavier D'Haultfœuille, Jérémy L'Hour +1

We consider inference for parameters of the form for some variables , and . Such parameters appear, in particular, in the ``changes-in-cha…

Using did_multiplegt_dyn to Estimate Event-Study Effects in Complex Designs: Overview, and Four Examples Based on Real Datasets

Clément de Chaisemartin, Diego Ciccia, Felix Knau +8

The command did_multiplegt_dyn can be used to estimate event-study effects in complex designs with a potentially non-binary and/or non-absorbing treatment. This paper starts by pro…

Treatment-Effect Estimation in Complex Designs under a Parallel-trends Assumption

Clément de Chaisemartin, Xavier D'Haultfœuille

This paper considers the identification of dynamic treatment effects with panel data, in complex designs where the treatment may not be binary and may not be absorbing. We first sh…

Analytic inference with two-way clustering

Laurent Davezies, Xavier D'Haultfœuille, Yannick Guyonvarch

This paper studies analytic inference along two dimensions of clustering. In such setups, the commonly used approach has two drawbacks. First, the corresponding variance estimator…

Linear Regressions with Combined Data

Xavier D'Haultfoeuille, Christophe Gaillac, Arnaud Maurel

We study linear regressions in a context where the outcome of interest and some of the covariates are observed in two different datasets that cannot be matched. Traditional approac…

Is Inference Conditional on Not Rejecting a Pre-test Less Reliable than Unconditional Inference?

Clément de Chaisemartin, Xavier D'Haultfœuille

Researchers often report an estimate and confidence interval only if a specification test does not reject - for example, only if a pre-trend test supports a difference-in-differenc…

Difference-in-Differences Estimators with Continuous Treatments and no Stayers

Clément de Chaisemartin, Xavier D'Haultfœuille, Gonzalo Vazquez-Bare

Many treatments or policy interventions are continuous in nature. Examples include prices, taxes or temperatures. Empirical researchers have usually relied on two-way fixed effect…

Partially Linear Models under Data Combination

Xavier D'Haultfœuille, Christophe Gaillac, Arnaud Maurel

We study partially linear models when the outcome of interest and some of the covariates are observed in two different datasets that cannot be linked. This type of data combination…

Difference-in-Differences Estimators for Treatments Continuously Distributed at Every Period

Clément de Chaisemartin, Xavier D'Haultfœuille, Félix Pasquier +2

When studying the effects of taxes, tariffs, or prices using panel data, the treatment is often continuously distributed in every period. We develop difference-in-differences (DID)…

Two-Way Fixed Effects and Differences-in-Differences with Heterogeneous Treatment Effects: A Survey

Clément de Chaisemartin, Xavier D'Haultfœuille

Linear regressions with period and group fixed effects are widely used to estimate policies' effects: 26 of the 100 most cited papers published by the American Economic Review from…

Identification and Estimation of Average Causal Effects in Fixed Effects Logit Models

Laurent Davezies, Xavier D'Haultfœuille, Louise Laage

This paper studies identification and estimation of average causal effects, such as average marginal or treatment effects, in fixed effects logit models with short panels. Relating…

Two-way Fixed Effects and Differences-in-Differences Estimators with Several Treatments

Clément de Chaisemartin, Xavier D'Haultfœuille

We study two-way-fixed-effects regressions (TWFE) with several treatment variables. Under a parallel trends assumption, we show that the coefficient on each treatment identifies a…

Difference-in-Differences Estimators of Intertemporal Treatment Effects

Clément de Chaisemartin, Xavier D'Haultfœuille

We study treatment-effect estimation using panel data. The treatment may be non-binary, non-absorbing, and the outcome may be affected by treatment lags. We make a parallel-trends…

An alternative to synthetic control for models with many covariates under sparsity

Marianne Bléhaut, Xavier D'Haultfoeuille, Jérémy L'Hour +1

The synthetic control method is a an econometric tool to evaluate causal effects when only one unit is treated. While initially aimed at evaluating the effect of large-scale macroe…

Rationalizing Rational Expectations: Characterization and Tests

Xavier D'Haultfoeuille, Christophe Gaillac, Arnaud Maurel

In this paper, we build a new test of rational expectations based on the marginal distributions of realizations and subjective beliefs. This test is widely applicable, including in…

Asymptotic results under multiway clustering

Laurent Davezies, Xavier D'Haultfoeuille, Yannick Guyonvarch

If multiway cluster-robust standard errors are used routinely in applied economics, surprisingly few theoretical results justify this practice. This paper aims to fill this gap. We…
