Economic Impacts on the Surrounding Counties of the Parkway 
An input-output model in terms of changes in total output, income, value added, and employment describes 
the economic importance of a tourism activity (travel to the Parkway, in this case). In this study, all input figures 
were deflated to year of the IMPLAN’s data base to obtain a consistent figure result. Then, after the economic 
activity calculations, all outputs were inflated to the forecasted year’s figures. Total output is the dollar value of 
goods and services produced to satisfy final demand for goods and services and the inter-industry transactions 
needed to produce them. Value added is equivalent to gross regional product (payments to labor, capital and taxes), 
or the value of total output minus input purchases. 
Type I, Type II, and Type III are three types of multipliers available within the IMPLAN system. Selection 
among these multiplier types has an important effect on the size of the impacts that are estimated. The Type I 
multipliers capture the inter-industry effects and exclude the induced effects. The Type II multipliers give the direct, 
indirect, and induced effects where the induced effect works by incorporating labor income and the household
