Why are my induced results different in the newest release of IMPLAN?
Seeing differing Induced Effects when comparing the results of the same Impact on the same geography and year of data in the new release of IMPLAN to past versions, is due to methodology improvements to the IMPLAN Social Accounting Matrix (SAM). One of the largest changes we've incorporated is to use gross commuting flows as opposed to net commuting flows. This means for all regions where there is both in-commuters and out-commuters, the In-Commuting Rate will be larger in the current version of IMPLAN (V5), reducing Induced Effects in the Impact Results.
This is because in these cases, total in-commuting dollars is always larger than net in-commuting dollars because net in-commuting dollars = total in-commuting dollars - out-commuting dollars.
Previously, net in-commuting dollars were divided by total Employee Compensation (EC) in the region to calculate an In-Commuting Rate. Now total in-commuting dollars are divided by total EC to generate an In-Commuting Rate. For single-region analysis, the In-Commuting Rate is applied as a reduction, along with the Payroll Tax reduction, to any EC value (in any Event that generates EC to the region) before it is run through the region as Household Income. This reduction represents the assumed leakage from workers in the Study Area leaving the Region to go home, where they spend their money. Multi-Regional Input Output analysis uses commuting data to track where in-commuters live so there is no change to the way MRIO results are calculated.
Some of the other SAM changes could have a positive effect on Induced Effects, so the overall effect won't always be a reduction in Induced Effects.
Other SAM changes include:
Previously, sub-national SAMs consolidated all commuting in the Domestic Trade account. Now, foreign commuting stays in the Foreign Trade account. Some payments to government have been reclassified, e.g., rents and royalties are paid from Other Property Income (OPI) to government, rather than from Taxes on Production and Imports (TOPI) to government, in the new Implan. Such changes serve to align Implan SAMs with the Bureau of Economic Analysis’s (BEA) National Income and Product Accounts (NIPAs) and to improve the quality of tax impact results.
How do I import Events from Excel?
The feature to import the Event Template into IMPLAN is coming soon. Luckily, Events are much more seamless to enter into the new platform!
How do I search for my Sector using a NAICS code or description?
A new and improved Sector Search feature is coming soon to IMPLAN. Currently you can search for Sectors by NAICS codes and descriptions using this Excel file.
