In addition to business plans, R.A. Wiedemann & Associates provides clients with the latest in economic impact analyses techniques and studies. Using the international expertise of Dr. Geoffrey J.D. Hewings, this portion of the business examines the direct, indirect, and induced impacts associated with airport development and improvement. R.A. Wiedemann & Associates uses the IMPLAN Input-Output Modeling System to measure specific and comparative economic impacts of airport development projects. IMPLAN not only quantifies the jobs, income, and output of various enterprises, it also assesses the tax impact for local, state, and federal revenues. Because Dr. Hewings is a Special Sworn Agent of the U.S. Census Bureau, R.A. Wiedemann & Associates has access to the U.S. Census Bureau’s establishment level data for businesses and manufacturing companies. As a result, we can offer clients real world estimates of economic impact that can be defended/promoted in either positive or negative public forums. In addition to economic impact studies, Dr. Hewings has completed complex economic studies for the U.S. Department of Commerce, the U.S. Department of Transportation, and the Federal Reserve Bank of Chicago.
