Difference-in-Differences Models in the Presence of Time-Varying Mediators
Kyunghoon Ban, Zhengrun Chen, Désiré Kédagni
We study difference-in-differences (DiD) designs in which a binary treatment changes an endogenous time-varying (continuous, discrete, or mixed) mediator that in turn affects an ou…
Local Average and Marginal Treatment Effects with a Misclassified Treatment
Kyunghoon Ban, Désiré Kédagni, Santiago Acerenza
This paper studies identification of the local average and marginal treatment effects (LATE and MTE) with a misclassified binary treatment variable. We derive bounds on the (genera…
Misclassification in Difference-in-differences Models
Augustine Denteh, Désiré Kédagni
The difference-in-differences (DID) design is one of the most popular methods used in empirical economics research. However, there is almost no work examining what the DID method i…
Evaluating the Impact of Regulatory Policies on Social Welfare in Difference-in-Difference Settings
Dalia Ghanem, Désiré Kédagni, Ismael Mourifié
Quantifying the impact of regulatory policies on social welfare generally requires the identification of counterfactual distributions. Many of these policies (e.g. minimum wages or…
Robust Identification in Randomized Experiments with Noncompliance
Désiré Kédagni, Huan Wu, Yi Cui
Instrument variable (IV) methods are widely used in empirical research to identify causal effects of a policy. In the local average treatment effect (LATE) framework, the IV estima…
Testing Identifying Assumptions in Parametric Separable Models: A Conditional Moment Inequality Approach
Leonard Goff, Désiré Kédagni, Huan Wu
In this paper, we propose a simple method for testing identifying assumptions in parametric separable models, namely treatment exogeneity, instrument validity, and/or homoskedastic…
