Economic Incentives for Controlling Trade-Related Biological Invasions in the Great Lakes

Abstract

Ballast water from commercial ships engaged in international trade has been implicated as the primary invasion pathway in over 60 percent of new introductions of invasive alien species (IAS) in the Great Lakes since 1960. Recent policies have recognized that IAS are a form of biological pollution and have become focused on preventing new introductions. Given that emissions-based incentives are infeasible for the case of biological emissions, we investigate the cost-effectiveness of various performance proxy-based and technology-based economic incentives to reduce the threat of new invasions of Ponto-Caspian species in the Great Lakes.aquatic nuisance species, ballast water, uncertainty, risk management, performance-based incentives, environmental subsidies, International Relations/Trade, Resource /Energy Economics and Policy,
