Readme for data on industry-level controls
Brendan Price
September 8, 2014

The file "mfg_sector_dummies.dta" contains indicators for ten broad manufacturing subsectors.

The file "investment_controls.dta" reports, for each manufacturing industry, computer investment as a share of total and high-tech investment as a share of total, both as computed in 1990.

These control variables are adapted from Autor, Dorn, Hanson, and Song (2014).
