  1. Note: The dependent variable is firm-level TFP calculated as TFP ijt  = ln(Y ijt ) - α jt  ln L ijt  - β jt  ln K ijt  - γ jt  ln M ijt , where i denotes firm, j denotes industry, and t denotes time. These measures are calculated using all the available data from the Industrial Surveys from 1990 to 1999.
