Prices of Goods' and ‘Bads’: An Application of the Ricardian Theory of Differential Rent

Pollutants, wastes and scrap appear as joint products of consumption or production processes. Leontief and other authors extend input–output (IO) tables such that additional products and industries, respectively, account for pollutants and abatement activities; they also analyze the effects of pollution control policies, by means of traditional IO methods. This approach does not account for choice of technique and, therefore, neglects the possibility of substitution. This paper proposes to utilize Ricardo's theory of differential rent, which is based on the possibility of coexisting technical alternatives.
