I understand that IMPLAN GDP deflators account for relative price changes over time. I saw in the glossary that it says “For projections into the future, we use the annual rate of change in output from the BLS' employment growth model.” --- does this apply to the GDP deflator as well as the Output deflator? What is the source for the BLS employment growth model and which parameters does IMPLAN use from it? When the GDP deflator is used to project into the future, does it reflect any other growth factors, such as projected productivity growth? The context for this question is that I am using 2013 data to project 2021 effects. How should I interpret the 2021 employment effects and GDP effects in IMPLAN?
