Multipliers and year adjustments
The direct effect displayed in the summary table for value added is $18.6 bil and for output is $24.0. The sum of my direct imputs is $22.0 billion. Should one of them match or why the differences?
I input all of my values in current dollars for each of the years, 2011-14, changes the event year for each year, and then elected in the analysis report to see the values in the dollars for each year (i.e., 2011, 12, 13, and 14). Was this correct?
Please respond to lynnreaser@pointloma.edu
Thank you very much.

IMPLAN SupportHi Lynn, We apologize in the delay of our response. The number that you would expect to correspond to Industry Sales is the Output value, and you have not done anything wrong in your analysis setup as long as you set Event Year PRIOR to entering your Industry Sales value. In the way you have setup the analysis, we would not expect the value of Output to equal the sum of the Industry Sales values because each Event Year dollar is, in effect, a different unit. Thus, just as you would need to convert mm, cm, m, and km into one of those units of measure to sum and display them, the software is adjusting your 2011, 2012, 2013 and 2014 values in the dollar value or unit that you set the Dollar Year for View field. Please let us know if you have any questions.0 -
Thank you. Although it appears that we did it correctly, could you look at the attached output results and let me know if the results look reasonable (e.g., the ratio of GRP to our initial spending input for each year expressed in current dollars for each of those years.) Best regards, Lynn Reaser0

IMPLAN SupportHi Lynn, A few things to note: 1. Output is not the same as budget, so if your Direct Spending does not include taxes and profits, then you may want to set up your analysis differently, as IMPLAN will assume that some portion of that value is taxes and profits, both of which get leaked (i.e., they cause no indirect or induced impacts) if you are using a standard Industry Change Activity. 2. If IMPLAN's Direct effect differs from your Direct spending, you may not be using the correct Dollar Year for View for comparison purposes. To compare the impacts of the 2011 Event to your Direct spending, set the DYV to 2011. If the values still do not match, feel free to zip up your model and send it to support@implan.com. Also, to ensure correct inflation/deflation, make sure you set the Event Year prior to entering any values. 3. Technically, a multiplier is unitless because it is calculated as: Output Multiplier = Total Output / Direct Output GDP Multiplier = Total GDP / Direct GDP Employment Multiplier = Total Employment / Direct Employment ...etc... In your spreadsheet, it appears that you are dividing Total GRP by Direct spending for more of a response coefficient (i.e., $ worth of GRP per $ direct spending)? Note that GRP is not the same as Output (aka Industry Sales). Rather, GRP is synonymous with Value-Added. Hope this helps, please let us know if you have additional questions.0 -
