Abstract

The REAcct (for Regional Economic Accounting) tool was developed for estimating order-of-magnitude economic impacts within DHS scenario analysis. REAcct uses input–output modeling, geo-spatial data computational tools, and publically available economic data and allows for detailed specification of sectors, regions, and disruption intervals. Direct impacts are estimated as changes in output and employment; total (direct plus indirect) impacts are calculated using regional total and final demand multipliers. In total, the REAcct framework and software allow for scenario analysts to understand and assess the interdependent relationships between critical infrastructures, economic industries, and consumers that are essential to broader homeland security scenario analysis.
