To come up with those estimates, Our City turned to Kelly Cunningham, an economist with the National University System, to study the economic impact of major businesses in the county. We looked at each company’s revenue and number of local employees to derive an estimated economic impact using Implan. Implan software uses an input-output analysis in conjunction with the flow of regional economic transactions and multiplier models.  It measures direct, indirect and induced effects to determine an overall impact.
