I am trying to measure the impact of an airline on the U.S. economy (using ABP method). I noticed that for both an "industry change" and "commodity purchase" activity for air transportation there is minor output going to "Aircraft Manufacturing" presumably because capital goods purchases are not captured. Would the best method be to estimate the value of aircraft purchased within the year from domestic producers and treat as an industry change? Would I need to make any adjustment to the industry spending pattern? Also what is the difference between a "commodity purchase" from an industry sector and an industry change?
