I was asked to assess the importance of manufacturing to a region. I think a multi-industry contribution analysis is the best approach, and I followed the steps on this page: http://implan.com/v4/index.php?option=com_multicategories&view=article&id=660:660&Itemid=14 I have three questions about the setup and results: 1) In general, what is the purpose for changing the coefficient cell for the primary commodity to 1? 2) What should I use for the “event year? I have the 2008 IMPLAN package, but I receive regular updates. Should I set the event year as 2008 or 2013? 3) My scenario results show I direct effect on employment of a little over 38,000 jobs. The latest QCEW manufacturing employment for the region is a little under 31,000 jobs. Is the difference a “red flag” that I did something wrong in the setup, or is there a reason I should expect the deviation? Thanks, Tom
