I am working on an analysis that is examining the impacts of changes to forestry harvest restrictions in Wisconsin. I am focusing on a few select counties, as well as larger regions within the state. Based on my conversations with the experts in this area, they feel that the primary group that would be impacted by changes to harvest restrictions would be the forest land-owners. We assumed that most of these individuals would be categorized in sector 15 - Forestry, Forest Products, and Timber Tract Production. However, upon examining the data for the three focus counties, all of them have zeroes in that sector - no employment, no output, etc... We have the names of some of these large private landowners, and we have been searching online to determine their NAICS classifications. It appears that they are classified in a wide variety of sectors (Wholesalers, Hotels, Manufacturing, Building materials, etc). It seems that most of these large private landowners probably earn some of their income from timber sales, but they have other businesses that they consider to be their "primary" source of income - often related to forestry products but often not. My first question is... how are the employment and output numbers in IMPLAN calculated? If a business classifies itself under multiple industries, are employment and output numbers divided amongst those industries, or are they all distributed to the primary classification? Secondly, in this case, would I be advised to impact sector 15 regardless of the fact that it doesn't "exist" in the region? I don't know how else to model the additional dollars. Thank you in advance for your help! Monica
