Input-output models in economic and environmental policy analyses

This paper discusses the use of input-output models for the analyses of economic growth and resulting environmental, resource and related issues. The emphasis is on discussion of a general structure and characteristics of the input-output models and on their uses for policy analysis. A large number of such analyses can be undertaken using input-output models. These include analysis of pollution generation by source for any specified time period, study of pollution generation trends under a number of economic assumptions, comparison of alternative pollution abatement costs, determination of the environmental and economic effects of alternative raw material inputs, analysis of economic and environmental impacts resulting from alternate output and/or end-product specifications, and others.
