The effect of global environmental regimes: A measurement concept

ABSTRACT. The article outlines a method to measure the effect which inter-national regimes have on solving global environmental problems such as global climate change. By using political–economic cost/benefit analysis, a no-regime counterfactual and a collective optimum (lower and upper bounds) are derived. By comparing the actual performance of a regime to these bounds, a simple coefficient of regime effectiveness can be computed. After theoretically deriving the various bounds, the authors discuss the determining factors and provide guidance on how such a research agenda could be pursued empirically. The authors conclude with suggestions to further refine the measurement concept and its merit for public policy
