Regional Economic Models, Inc. (REMI) Model

(Redirected from REMI)
Jump to: navigation, search
REMI is a dynamic model to assist policy- and decision-makers in five main topic areas, including energy, environment and economic development. The model incorporates four major approaches: Input-Output, General Equilibrium, Econometric, and Economic Geography modeling.

This tool is included in the Development Impacts Assessment (DIA) Toolkit from the LEDS Global Partnership.


The core of the REMI model is an input-output model that represents inter-industry relationships. This way, the industry structure of a particular region is captured within the model, as well as transactions between industries. The REMI model can represent long term general equilibrium between the supply and demand as prices, production, consumption, imports, exports, and other changes occur to stabilize the economic system. The model's equations and responses are estimated using advanced statistical techniques. The model is also capable of capturing the spatial dimension of the economy. This incorporates the productivity and competitiveness benefits due to the concentration, or agglomeration, of economic activity in cities and metropolitan areas, and to the clustering of industries.

"The REMI model is a dynamic forecasting and policy analysis tool that can be variously referred to as an econometric model, an input-output model, or even a computable general equilibrium model. In fact, REMI integrates several modeling approaches, incorporating the strengths of each methodology while overcoming its limitations. The result is a comprehensive model that answers “what if…?” questions about your economy. "
