Two-Level Games
Putnam's model of international negotiation as simultaneous play at domestic and international tables.
Two-Level Games is the framework articulated by Robert D. Putnam in his 1988 International Organization paper 'Diplomacy and Domestic Politics: The Logic of Two-Level Games,' modeling international negotiation as simultaneous interaction at two interconnected tables: the international table (where state representatives bargain with their counterparts) and the domestic table (where leaders must secure ratification or implementation from domestic political constituencies). The central insight: international agreements that are achievable at the international table may be impossible to ratify domestically, while domestic positions that are politically sustainable may be unacceptable to international counterparts. Successful negotiators must simultaneously craft agreements that are mutually acceptable internationally and ratifiable domestically — the 'win-set' (the set of agreements that would secure majority domestic ratification) defines the feasible negotiating space, and overlapping win-sets among states define agreements that can both be reached and implemented. Strategic implications include: leaders sometimes have advantages from credible domestic constraints ('I'd love to agree but my legislature would never ratify' is sometimes a real constraint and sometimes useful negotiating leverage); leaders can use international agreements to pressure domestic opposition or vice versa; uncertainty about each side's win-set complicates agreement; and negotiation strategy must address both audiences simultaneously. The framework has been substantially influential in international political economy, EU integration analysis (where the two-level metaphor extends to multi-level governance), and trade negotiation analysis (NAFTA, Uruguay Round, Doha, etc.). The framework integrates international relations with comparative politics, addressing the long-standing analytical separation between the two subfields.
Core components
- Two simultaneous tables: international negotiation and domestic ratification
- Win-sets (set of agreements that secure majority domestic ratification)
- Overlapping win-sets define feasible international agreements
- Strategic use of domestic constraints
- Distinction from purely international or purely domestic-political analyses
- Application to ratification problems (treaties, trade agreements)
- Connection to multi-level governance frameworks (EU, federalism)
- Integration of IR and comparative politics
- Domestic and international audience effects
Primary use case
Foundation for analyses of international negotiation and ratification; foundation for substantial work on international cooperation, trade negotiations, EU integration, and treaty politics; reference framework in international political economy and comparative politics; basis for analyses of executive-legislative relations in foreign policy; integration of IR and comparative politics traditions; pedagogical reference in international relations and foreign-policy education; foundation for empirical work on which international agreements achieve ratification.
Common criticisms
- The 'two levels' metaphor oversimplifies in many contexts — most international agreements involve more complex multi-stakeholder processes including international organizations, transnational advocacy, sub-national governments, and private-sector actors
- specifying win-sets empirically is genuinely difficult — what would secure ratification depends on substantial uncertainty and political contingency
- integration with rationalist game-theoretic models has been productive but has sometimes obscured ideational and institutional factors
- tendency in some applications to be metaphorically rather than analytically applied
- commercial and political invocation of 'two-level games' often departs from academic framework
- cross-national variation in domestic ratification processes (presidential vs parliamentary, federal vs unitary, strong vs weak parties) substantially affects framework operation
- the framework focuses on negotiating leaders' strategy when actual outcomes often depend on institutional and structural factors leaders don't control
- integration with constructivist analyses of how 'win-sets' are constructed is incomplete
- the framework has been more useful as analytical lens than as predictive theory.
