Game theory and mechanism design explain why actors who share a risk often underinvest in reducing it, and how rules can change that. In this field they are applied to treaties, joint institutions, risk pools and intergovernmental bargaining, to show which arrangements are self-enforcing and which depend on goodwill.
Game theory and mechanism design study strategic interaction among decision makers and the design of rules that lead to desired outcomes. They explain cooperation, free riding and incentives in shared-risk settings. In policy, governance and institutions and risk management and systemic risk, game theory clarifies why actors underinvest in shared risk reduction and how agreements can be made self-enforcing. It informs the design of risk pools, treaties and incentive schemes. The canonical description is on the STEM Commons.
Stability of a transboundary agreement
Each party's gains from cooperating and from acting alone are set out, and the analysis asks which provisions, such as side payments, issue linkage or joint monitoring, keep cooperation in every party's interest.
Design of a regional risk pool
Contribution and payout rules are examined for adverse selection and free riding, and alternative rules are compared for whether members would join and stay.
Intergovernmental fiscal bargaining
Transfers between national and local governments are modelled as repeated bargaining, to show how rules on bailouts and matching funds shape local incentives to invest in prevention.

06Validation
How results are checked.
Predictions are tested through laboratory and field experiments and comparison with observed behaviour. Mechanism designs are piloted before scaling.
Check
How it is done
Assumption audit
Rationality, information and the number of players are stated, and results are re-run with each assumption relaxed
Behavioural comparison
Predictions are compared with observed behaviour in experiments or past negotiations
Robustness to payoffs
Payoff estimates are varied to show where conclusions change
Assumptions of rationality and common knowledge often fail. Real settings involve many players and incomplete information.

Game theory for shared risk: Cross-border dialogue
The programme gathers national questions, finds shared dependencies and classifies evidence; parties may decline, decide for themselves, and the programme creates no treaty.
01 Questions and dependencies
