The secondary impact of nonpoint-pollution controls: A linear-programming-input/output analysis

A joint linear-programming-interindustry model is used to estimate the impact on small regional economies of nonpoint-pollution controls on agriculture. Results from the linear-programming submodel of the farm-production sector of a region are entered as final-demand changes in the “rows-only” interindustry model of the regional economy. Emphasis is placed on describing the models, the linkages between them, and on evaluating the usefulness and limitations of the modeling approach. A brief review of empirical results is also given.
