The coordinate plane of global governance.

The ‘coordinate plane of global governance’ developed in this paper describes the trade-off between static gains and dynamic losses associated with international policy harmonization. A simple model illustrates how potential gains result from producing positive international spill-overs, whereas potential losses come from restricted systems competition between national policy regimes. The solution to this model allows identifying the cut-off level between policies suitable for global harmonization and policies which should better not be centralized. An application of the concept to selected policy fields illustrates its relevance for decision-making on global governance. [ABSTRACT FROM AUTHOR]
