Liberal institutionalism
How international institutions make cooperation possible under anarchy.
Conceptual diagram, not data.
Liberal institutionalism accepts much of realism's starting point (states are central actors operating without a world government) but reaches more optimistic conclusions about cooperation. Its central claim is that international institutions, understood broadly as rules, norms and organisations, can help self-interested states achieve gains they could not secure alone.
Key thinkers. Robert Keohane's After Hegemony: Cooperation and Discord in the World Political Economy (1984) argued that institutions created under a dominant power can persist after that power's relative decline, because they continue to serve members' interests. Institutions do this by reducing transaction costs, providing information, increasing transparency and lengthening the 'shadow of the future', so that cheating today risks losing benefits tomorrow. Earlier, Keohane and Joseph Nye's Power and Interdependence (1977) introduced 'complex interdependence', a condition with multiple channels of contact between societies, no fixed hierarchy of issues and a reduced role for military force.
Debates. Realists respond that states care about relative as well as absolute gains, which limits cooperation, and that institutions mostly reflect underlying power. Institutionalists reply that much of the time the relevant problem is coordination and trust rather than fear of a partner's relative advantage.
Applying it today. The multilateral trading system and multilateral peace operations are natural test cases. Questions about financing shortfalls, mandate renewals and the shift towards ad hoc coalitions are, in institutionalist terms, questions about whether existing institutions still offer members enough benefit.
