The purpose of this paper is to quantify the economic impact of the Clean Air Act Amendments of 1990. The long-run cost of environmental regulations enacted prior to 1990 amounts to 2.59% of the U.S. national product. The new legislation will reduce the national product by a further 0.6% when the impact is complete. Electric utilities and primary metals industries will be especially hard hit by this legislation.
