The REMI model is a structural economic forecasting and policy analysis model.  It integrates input-output, computable general equilibrium, econometric, and economic geography methodologies.  It is dynamic, with forecasts and simulations generated on an annual basis and behavioral responses to compensation, price, and other economic factors.

The model consists of thousands of simultaneous equations with a structure that is relatively straightforward.  The exact number of equations used varies depending on the extent of industry, demographic, demand, and other detail in the specific model being used.  The overall structure of the model can be summarized in five major blocks:  (1) Output, (2) Labor and Capital Demand, (3) Population and Labor Supply, (4) Wages, Prices, and Costs, and (5) Market Shares. The blocks and their key interactions are demonstrated in Figures 1 and 2.
