Experimental-Selection-Correction-Replication-Code

Replication Code for Athey, Chetty, and Imbens (2025)

This repository contains replication code for the working paper "The Experimental Selection Correction Estimator: Using Experiments to Remove Biases in Observational Estimates".

The R code provided implements our experimental selection correction method that demonstrate how experimental data can be used to debias observational treatment effect estimates.

Repository Structure

• All code is contained in the code/ folder.

• The two main scripts are:

  • ESC_main_code_ext.Rmd: main code that implements the analysis in the paper.
  • ESC_prototype.R: a prototype code for our main method, Experimental-Selection-Correction.
