This repository contains Stata .do files for my comment on "Subways and Urban Air Pollution", Gendron-Carrier et al. (2022).

To combine my code with the data, first download this repository, then download the original replication package and extract the folders 'data/' and 'data_analysis/' to the directory 'data/GendronCarrier_etal_2020_replication/data_proccessing/'. This requires signing up for an ICPSR account.

To rerun the analyses, run the file run.do using Stata (version 15). Note that you need to set the path in run.do on line 2, to define the location of the folder that contains this README. Required Stata packages are included in 'code/libraries/stata/', so that the user does not have to download anything and the replication can be run offline. The file code/_config.do tells Stata to load packages from this location.

Figures and tables are saved in 'output/'; that directory is created by code/_config.do. It takes approximately 20-30 hours to run the code using Stata-SE. It helps to close web browsers to free up memory.
