This question is somewhat addressed in post #11398. There appears to be substantial changes in IMPLAN Sector #20 (Extraction of oil and natural gas) and IMPLAN Sector #28 (Drilling oil and gas wells) from the 2009 to 2010 IMPLAN data. Please see the examples in the attached workbook. I’ve included three states; the trend is similar in other states as well. As discussed in post #11398, value added has generally increased from 2009 to 2010 coinciding with an increase in direct employment impacts and a decrease in indirect employment impacts. Is there any insight regarding what is driving the changes to the structure of these sectors and how those changes could be realized in just one year? Also, when looking at total employment effects, both sector 20 and 28 are showing substantial increases in their multipliers. Any insight into this overall change in effects for these sectors? Your help is much appreciated.
