Economic Analysis Models/Tools for Air Pollution Regulations

EPA develops models and tools for estimating the costs and economic impacts of air pollution regulations. Information is provided below concerning the economic analysis models and tools maintained by EPA.

EMPAX-CGE

EMPAX-CGE is a regional computable general equilibrium (CGE) economic model designed to estimate regional macroeconomic impacts of environmental regulations on the U.S. economy. Many major regulations directly affect a large number of industries and/or substantially impact markets for key factors of production. In either case, there may be substantial indirect impacts resulting from changes in production, input use, income, and consumption patterns for directly affected markets. EMPAX-CGE offers the ability to trace economic impacts resulting from policies such as large-scale environmental regulations as the impacts are transmitted throughout the economy. 

Contact us for any of the documents listed below.  EPA will not be able to provide any support for any use of the model.
