Augmenting the Input-Output Framework for 'Common Pool' Resources: Operationalising the Full Leontief Environmental Model

In its initial formulation, the full Leontief (1970) environmental model augments the conventional Input-Output (IO) table by introducing pollution generation and separately identified pollution elimination sectors. Essentially it extends IO analysis to incorporate the use of a 'common pool' resource. Subsequent literature has either been analytical in nature or has concentrated on pollution generation but not cleaning activity. In this paper we generate an empirical full Leontief environmental IO system, based on augmenting the existing Scottish IO tables through endogenising waste generation and waste disposal activity. Due to weaknesses in data, our empirical results need to be treated with some caution. However, the construction of the extended IO system and the interpretation of the output and price multiplier results raise a number of interesting practical and conceptual issues. The analysis undertaken here can be extended to other 'common pool' resources such as the use of highways and irrigation systems.Input-output, environment, pollution, waste disposal, common pool resources,
