Event Studies with Feedback
Irene Botosaru, Laura Liu
Event studies often conflate direct treatment effects with indirect effects operating through endogenous covariate adjustment. We develop a dynamic panel event study framework that…
Time-Varying Heterogeneous Treatment Effects in Event Studies
Irene Botosaru, Laura Liu
This paper examines the identification and estimation of heterogeneous treatment effects in event studies, emphasizing the importance of both lagged dependent variables and treatme…
An Adversarial Approach to Identification
Irene Botosaru, Isaac Loh, Chris Muris
We introduce a new framework for characterizing identified sets of structural and counterfactual parameters in econometric models. By reformulating the identification problem as a…
Identification of Time-Varying Transformation Models with Fixed Effects, with an Application to Unobserved Heterogeneity in Resource Shares
Irene Botosaru, Chris Muris, Krishna Pendakur
We provide new results showing identification of a large class of fixed-T panel models, where the response variable is an unknown, weakly monotone, time-varying transformation of a…
