Hi: I am a long-time IMPLAN user. I download the multipliers and related parameters into a spreadsheet to run my impacts. Using the primary output multipliers, I calculate the sales, earnings, value-added, jobs, and IBT impact results. Using the previous edition of IMPLAN--- the impacts reported from my spreadsheet and the IMPLAN software were exact. Using the new software I am noticing some differentials ---some significant. On my test runs the sales (output) impacts were within 0.1%; the reported earnings and value-added impacts were within 1.5%. More troubling are the jobs impacts which were about 7% higher than reported by IMPLAN and the IBT which was about 20% higher than IMPLAN. What is the differences? Thanks for your assistance.
