IELab USA

US IE Lab 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 US IE lab follows the same architecture as other IE labs and contains a time series of sub-national MRIO tables. Methodology of creation of the US IE lab is similar to all other IE labs where the national level IO table provides the starting point, these national IO tables are then disaggregated to create the sub-regional MRIO tables based on non-survey approaches and adding constraints to balance the sectoral outputs.

The current MRIO table in IE Lab has 20 sectors (NAICS 2 digit code level) and 52 states ready for analysis. However, the users can tailor the MRIO tables at 72, 402 and 1,058 sector level based on the disaggregation level required for their own analysis. The US Lab is hosted on a server at University of Sydney and can be accessed remotely to run analysis. The data required to build the US lab comes from the US Bureau of Economic Analysis (US BEA), that provides the national level IO tables and GDP data which is used as one of the constraints for disaggregation. Utilizing a time series or forecast of GDP, the US Lab also provides a capability of generating a time series of US MRIO tables. To be able to use US Lab, users should be familiar with Matlab and ALANG files that form the foundation of IE Lab structure. 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 and is currently being 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.
