    Hello Inder, This article discussing analyzing military bases may be of interest to you. http://support.implan.com/index.php?option=com_content&view=article&id=392 In response to your questions: You will need to have all of the Activities/ Events entered first in your Core Region before any Models can be linked. IMPLAN is a step wise process and will not let you set up your Scenario or link any regions together before any Activities/Events are created. MRIO does not capture all leakages. MRIO captures the leakages from the core region to the attached region(s) and from the attached region(s) to the core region. Aggregating your 3 counties into a single Model gives a total average and you lose each counties regional identity (per worker values). If your aggregated 3 county region consists of the same counties that make up your MRIO study, it is possible that the aggregated region results in a higher impact. If you are interested in keeping regional identity and want to see the impact of the core region on the linked regions, then you will want to use MRIO. If you do not mind, could you send in both Models to support@implan.com so that we can look at your results. Regards, IMPLAN Staff

    Thanks. Your response was very helpful. As requested, I am attaching a file showing the IMPACT Summary results of two models: regional model that includes the three counties in close proximity each other and the other model that uses MRIO analysis. You will note the latter model impact is less than the former. One would expect that the MRIO impact will be more than the regional impact because MRIO captures all the leakages. I am curious how do we separate the economic impact of the core county from the other two counties in MRIO analysis.

    Hello Inder, Thank you for the additional information. When conducting an MRIO analysis, the results screen automatically separates the impact of the core region from the other linked regions. When first navigating to your MRIO results, you will see the impacts on the core region (this will be the only region with Direct Impacts). You can view the impacts on your linked regions by selecting the linked regions in the Models Included window. http://support.implan.com/index.php?option=com_content&view=article&layout=edit&id=369 Note: if you want to see overall impact totals, you will need to add the results from each region. This will increase your total impact values. Your lower total impacts will be due to net in-commuting. IMPLAN operates under the assumption that employees spend their money where they live. If an employee lives in County B but works in County A, the pay the employee receives as part of an impact in County A leaks from the region, as the employee is assumed to spend earnings in County B. Therefore, IMPLAN reduces impact Employee Compensation (EC) to account for in-commuting prior to splitting the EC amount across the Household Spending Patterns. You can determine if your region has a net in-commuting rate by going to Social Accounts > IxC Social Accounting Matrix and taking note of Employee Compensation column payments to Domestic Trade. For regions that are net out-commuting, this value will be 0. Below are the individual commuting rates for your counties using 2014 data: Cumberland Commuting Rate: ~17% Hoke County Commuting Rate: 0% Harnett County Commuting Rate: 0% Below is the commuting rate for your three county aggregated region. Aggregated 3 County Region: ~3% Because the aggregated region's commuting rate is smaller than the MRIO Core region's commuting rate, the EC related to the aggregated region's impact will be reduced less than the EC related to the MRIO's Core Region. You can find more about IMPLAN commuting and how to adjust commuting at the link below. http://support.implan.com/index.php?option=com_content&view=article&id=254:254&catid=230:230 Regards, IMPLAN Staff

    Hello Inder, In reviewing your spreadsheet, it appears that your Direct Output is higher than your Value Added. This is generally expected, as Output = Intermediate Expenditures (IE) and Value Added (VA). However, sectors 535 and 536 are special payroll sectors and do not include Intermediate Expenditures. Therefore, your VA should equal your Output. Based on your provided information, it appears that you may be using employment as your initial input and then are altering the Employment Compensation (EC) to match some known values you have. If you have both Employment and EC, we suggest entering your EC value first and then modifying your event's employment value to match your known employment. Regards, IMPLAN Staff
