The Louisiana Economic Impact Model (LEIM) is a Leontief style input-output model customized for the Louisiana economy. Special attention is given to the geographic distribution of economic impacts and tax impacts.

About LEIM

LEIM is based on the Regional Input-Output Modeling System (RIMS II) that is constructed by the U.S. Bureau of Economic Analysis (BEA). LEIM then allocates economic impacts across parishes of the state using gravity models of trade, producing parish-specific estimates of economic activity supported by an initial shock regardless of the initial location. This feature is particularly helpful for economic developers interested in a specific region. LEIM also considers Louisiana tax structure explicitly in provided estimated tax revenues supported by an economic shock. Local tax impacts are based on specific information about property and sales tax down to an individual parish. LEIM also includes a module to estimate direct property taxes, taking into account Louisiana's Industrial Tax Exemption Program (ITEP), for a new investment. 

Model Access

LEIM is available through a web application. Please contact ces@lsu.edu for more information.
