Sources: Calculations are by consultants. The calculations are explained in the text, in section "Weights of Inputs". Data for output, labor, and intermediate inputs were obtained from BEA Industry Accounts at: http://www.bea.gov/bea/dn2/gdpbyind_data.htm. Data for fixed assets, from Fixed Asset Accounts at: http://www.bea.gov/bea/dn/FA2004/Details/Index.html.

Note: The weights of the three inputs indicate their relative share in total industry costs. They add up to 1.00 (total industry costs).
