Elinor Ostrom (2009), Prize Lecture, 8 December 2009, Les Prix Nobel; reprinted in American Economic Review 100(3):641–672 (2010) — DOI-10.1257/aer.100.3.641
Key takeaways
- Polycentricity. “Many centers of decision making that are formally independent of each other”; whether they function as a system “is an empirical question in particular cases” (V. Ostrom, Tiebout & Warren 1961, quoted §2A). In US metropolitan policing, areas with many autonomous producers had more efficient producers, and duplication was rare: “complexity is not the same as chaos”.
- Design principles. The design principles of Governing the Commons (LIT-737) are given in an updated form (§4E): clear user and resource boundaries; rules congruent with local conditions and costs proportional to benefits; collective-choice arrangements; monitoring of users and of the resource by users or those accountable to them; graduated sanctions; fast, cheap, local conflict resolution; recognition of the right to make rules; and nested enterprises. About two thirds of over 100 studies reviewed by Cox et al. (2009) confirm them.
- Experiments. Without communication, subjects overuse a common pool beyond the Nash prediction. Face-to-face “cheap talk” raises joint returns. Costly sanctioning is used, and raises gross but lowers net returns. Groups that chose their own sanctioning system reached 90% of optimum (§5A). An externally imposed rule with weak inspection crowded out cooperation in a Colombian field experiment (§5B).
- Field evidence. Farmer-governed irrigation in Nepal outperformed government systems on all three measures. In forests, local monitoring predicts forest condition, and formal protected status does not (§6).
- No panaceas (§8). What matters is how an arrangement “fits the local ecology, how specific rules are developed and adapted over time, and whether users consider the system to be legitimate and equitable”.
Standing in the record
Filed on 2026-10-05 at the owner’s request, as the readable source for an essay’s citation of “Ostrom’s work on differentiated and polycentric governance” (§8.2). The account is THEORY-149.
The essay cites Ostrom for distributed monitoring and authority. Principles 4 and 8 are the most specific support for that. But the principles concern users governing a resource they depend on. A corporation governing itself is a further application the essay would need to argue for.
