North American economic integration and industrial pollution in the Great Lakes region

This paper provides an assessment of the impact of increased economic integration within North America on industrial pollution intensities within the Great Lake states of the United States. It utilizes a three-country, applied general equilibrium model of the North American economy, data from the World Bank's Industrial Pollution Projection System, and employment data from the US Bureau of Economic Analysis to simulate the industrial pollution impacts of North American trade liberalization within the Great Lakes region. The results reflect the liberalization of tariff and non-tariff barriers, their trade and production impacts, state-level shares in the production changes, and the resulting industrial effluent changes. Two trade liberalization experiments show that, in many cases, the Great Lake states account for a substantial portion of the total emission changes caused by North American economic integration, Of particular concern to the Great Lake states are the emissions of the base metals, transportation equipment, and petroleum sectors.
