india-irrigation-canals-paper

This is the replication repository for "The Long-Run Development Impacts of Agricultural Productivity Gains: Evidence from Irrigation Canals in India" (Asher, Campion, Gollin, Novosad)

This repository contains the code required to replicate all tables and figures from the paper. Replication data can be found in this Google Drive folder: link.

Dataset list

• canals_analysis_data.dta: main analysis dataset at the village and town level
• canals_spillovers.dta: additional variables used for the spillovers analysis at the village and town level
• canal_construction_data.dta: canal data on construction, at the canal segment level (matching to the GIS data)
• pc81_canals_working.dta: National Sample Survey data on migration at the individual level, with district-level variation in canal coverage
• pc51_balance_data.dta: subset of main data matched to 1951 villages with canals constructed after 1951
• town_panel_equal_area.dta: town panel data

Replication Instructions

1. Open canals_config.do
2. Change the following filepaths saved as globals:

Filepath	Description
ccode	the base filepath for the repository
cdata	the folder where the data files (from Google Drive link above) are saved
out	the folder where you want all outputs saved
tmp	a scratch folder where intermediate outputs can be saved

3. Run canals_config.do in Stata. This will set all configurations, no need to change any other files.
4. Open make_canals_analysis.do and run in Stata.

Computational requirements

Most code is run in Stata, with the relevant packages included in the ado folder in this repository.

The exception are the coefficient plots which are created using python. Only a very few basic packages are required: pandas, matplotlib, and numpy. Ensure that whatever python environment you are using is activated (i.e. Stata knows where to access the environment) before running the make_canals_analysis.do file in Stata, as it will call the code requiring python.

Or, if you do not want to run the python-dependent code, comment out the lines in the Figures section of the make_canals_analysis.do file before running it.
