    HI Jennifer! Thank you for your forum post. Would you mind providing us with additional information about those workers. Do those workers work for the same company but for plants outside Calhoun county, a mix of those working in Calhoun and elsewhere, or something else. Once we have a better sense of what those jobs are, then we can better assess how to respond. Thanks! IMPLAN Staff!

    The workers I gave percentages on work for that institution but reside in the region (30% (846)) or the rest of the state (7% (199)) and commute to work. I don't always have this data but because I did, it made the IMPLAN MRIO output results look questionable. Region and Rest of the State look really low. Primary study area looks high. Thanks so much for your help!

    Hi Jennifer, Thank you for sharing that information, it helps a lot. Even though those workers live in other areas in the state, by definition their jobs are site-based so they would be in the core regions job estimates, in other words even though they are residents in other areas the only place in the Model where you will see their Employment is in Calhoun county, because that is where they work. It sounds like your second concern is that you don't feel that the Model is properly distributing income of those workers to the regions of their households. There are a couple of things we can see that could be at play here that are creating your concerns: 1. It's important to remember that the jobs supported in the MRIO linked regions are jobs from income spending (Induced Effects) of those workers that are counted in the Employment numbers of the core county, and the jobs supported by any businesses that the core county may purchase from as part of it's input requirements (Indirect Effects). 2. The commuting rates are net regional commuting rates and are unfortunately not Sector specific, so it may well be that the business you are studying has a greater income distribution across these regions than this average. If this is the case, then you can certainly create an MRIO series to try to capture these income effects, but to do this, you would need to have an estimate of the Employee Compensation and/or Proprietor Income that was going from the factory into each of the linked regions. This article briefly describes the setting up of an MRIO Series. http://implan.com/index.php?option=com_content&view=article&id=427#model-setup. In this case you would need to create 9 Models (the first three as described in your post) would include the analysis as you have setup, with the exception of the fact that you would reduce the Employee Compensation and Proprietor Income values by the amounts that you knew leaked through commuting workers to other regions (less the commuting factor which can be found in the SAM at http://implan.com/index.php?option=com_content&view=article&id=254) and re-run the analysis. You could then do this again for each of the other two regions, using a Labor Income Change to see the effects of that income the region and it's feedback to the core and second region. Hopefully this helps --Implan Support Staff
