Estimating economic output and payroll by sectors

Hello, I was wondering the best way to estimate total economic output, average output per employee, and average wages per employee by IMPLAN sector for large projects with impacts to multiple sectors. I typically run the model with the user interface by inputting the number of jobs or expenditures as a result of project implementation, etc. by IMPLAN sector to get a final output (which includes the total number of direct, indirect, and induced jobs, payroll, and economic output, etc.). I also run the model for total jobs by IMPLAN sector although I am not aware of using the user interface to do this for economic output/GRP or payroll by each individual sector. I believe I could run each IMPLAN sector individually in the model or through the I-O matrices via converting them to Access/.csv but I'm not entirely certain. Could you recommend the easiest way to accomplish this, lay out the steps, and explain possible data limitations with using IMPLAN data for these calculations? Thank you, Sonya

  Hi Sonya, With reference to running the model by inputting the number of jobs or expenditures (by IMPLAN sector) for each project, you can calculate Output per Worker by dividing Total Output Impact by the Total Employment Impact. However, note that this Output per Worker figure is a weighted average of the output per worker of all sectors involved (directly, indirectly, and induced via household spending) so it doesn't have a clear interpretation except perhaps in comparison to other projects. With reference to running the model for total jobs by IMPLAN sector - if you are just interested in pulling the Output per Worker, Labor Income per Worker, and total Output by Sector from IMPLAN, these can all be found in the Explore> Study Area Data. Totals for each of the local 440 industries will display on the View By: "Industry Detail" sheet that displays when the Explore>Study Area Data opens. The View By: "Industry Summary" sheet will show the average per worker values for each industry in the Model. Otherwise, if you want to run the entire industry employment as an impact, you will again be getting an "average" output per worker. Running the entire industry's output or labor income will give you the exact same results as running the entire industry's employment. Please let us know if we have misinterpreted your questions - if this is the case, any additional explanation you can provide would be helpful.
