RDP 2025-01: Are Investment Tax Breaks Effective? Australian Evidence Read me file

Nu Nu Win, Jonathan Hambur and Robert Breunig

February 2025

This ‘read me’ file details the replication files for RDP 2025-01. Firm level of the data cannot be provided as they are confidential unit record data contained in the ABS Business Longitudinal Analysis Data Environment (BLADE). All data used to plot figures appearing in the RDP are available to the public and can be found in the spreadsheet ‘rdp-2025-01-graph-data’. The ‘Codes’ folder contains Stata's do files that are used to produce the results presented in the paper and the appendices. The Stata codes were run on Stata MP 16 (64 bit) and draw on the files in the ‘ado’ folder.

If you make use of any of these files you should clearly attribute the authors in any derivative work.
