  1. Productivity is demeaned by sample average (not technology-specific averages)
  2. No. represents the number with furnaces of each technology in each year
  3. The last column, (BOF) − (OHF), indicates the average productivity difference between the BOF and OHF. It takes a positive value (+) if BOF productivity is higher than that of OHF
