US IE Lab (USLab) provides a Multi-Regional Input-Output (MRIO) database that can be used to study economic impacts of changes intended across the US economic system. The USLab follows the same architecture as other IE labs and contains a time series of sub-national MRIO tables. The input data to the lab consists of national level IO tables as the starting point along with data for constraints on state level GDP and labor data. These national IO tables are then disaggregated to create the sub-regional MRIO tables based on non-survey approaches and constraints added to balance the sectoral and regional outputs.
The USLab can generate MRIO tables at several levels of regional and sectoral aggregation. Region options include 52, 9, and 5 regions corresponding to the 50 states plus Washington, DC and Puerto Rico, and two US Census Region levels, respectively. Users can tailor the MRIO sector aggregation to 21, 100, 312, 708, and 1,058 sectors, corresponding to NAICS codes, based on the disaggregation level required for their own analysis.The USLab is hosted on a server at University of Sydney and is accessed remotely to run analysis. The data required to build the USLab comes from the US Bureau of Economic Analysis (US BEA), that provides the national IO accounts and state GDP data, which are used as some of the constraints for disaggregation. Other optional constraining data include commodity flow survey, exports/imports, and consumer spending data. Using a time series or forecast of GDP, the USLab also provides a capability to generate a time series of US MRIO tables. Currently, data for years 2012-2017 has been included. To be able to use USLab, users should be familiar with Matlab and ALANG files that form the foundation of the IELab structure and the supply and use framework for constructing IO tables. This is the first MRIO Lab platform available for US that can use different non-survey methods to study the structural variations in MRIO tables.The lab has been used to study the economic impact of desired economic changes (such as renewable energy transition, low carbon economy etc.) in the US economy across all states along with satellite energy impacts. A satellite account of employment data from the Bureau of Labor Statistics’ QCEW is also available. Currently, the capabilities are being expanded to perform GHG analysis by developing a satellite account that contains data on associated emissions for each sector.
