Policy, institutional and decision science
Policy, institutional and decision science studies how public decisions are made, implemented and evaluated. It examines how institutions coordinate across sectors and levels of government when facing shared risks. Policy Nexus stewards this page for the Nexus Consortium.

The short answer.
Policy, institutional and decision science studies how public decisions are made, implemented and evaluated. Policy science identifies governance gaps where responsibility for cross-sector risk is unclear. In the Nexus Consortium, Policy Nexus stewards its canonical page, and 10 other platforms apply it, including Research Nexus and Innovation Nexus.

What policy, institutional and decision science covers.
- 01
Core methods
policy analysis; institutional analysis; regulatory impact assessment; stakeholder mapping; programme evaluation; comparative case study.
- 02
Data and instruments
legislation and regulatory texts; government budgets and audits; administrative data; expert elicitation; case study archives.
- 03
Validation
Conclusions are tested through comparative cases, counterfactual evaluation and peer review. Implementation outcomes are monitored against stated objectives.
- 04
Limits
Findings are often context specific and difficult to transfer. Political dynamics can override technically preferred options.
- 05
Use in risk decisions
Policy science identifies governance gaps where responsibility for cross-sector risk is unclear. It supports the design of mandates, coordination mechanisms and accountability.
Policy science draws on evaluation and governance standards.
| Reference | What it sets |
|---|---|
| OECD Recommendation on the Governance of Critical Risks | Whole-of-government approach to critical risks |
| IRGC risk governance framework | Matching governance style to risk type |
| OECD DAC evaluation criteria | Relevance, coherence, effectiveness, efficiency, impact, sustainability |
Institutions as part of the system.
Mandates, coordination failures and incentives determine whether known risks are acted on. Policy science studies institutional design and evaluates what policies achieved. In systemic analysis it identifies where no institution owns a risk and where mandates overlap or conflict.
- Map mandates before recommending action.
- Evaluate implementation, not only design.
- Distinguish policy analysis from policy advocacy.
