American political economist (1933-2012) and Nobel laureate in economics (2009) whose empirical work on commons governance established the eight design principles for long-enduring commons and the polycentricity thesis. Her work was associated with the New Institutional Economics and the resurgence of political economy.

Contribution

Ostrom’s Governing the Commons (1990) was partly inspired by the errors in Garrett Hardin’s “Tragedy of the Commons.” Where Hardin argued that shared resources inevitably degrade without private ownership or state control, Ostrom documented hundreds of cases where communities successfully governed shared resources through self-organized institutions. Her eight core design principles for governing commons are:

  1. Clearly defined boundaries.
  2. Proportional equivalence between benefits and costs.
  3. Collective-choice arrangements.
  4. Monitoring.
  5. Graduated sanctions.
  6. Conflict-resolution mechanisms.
  7. Minimal recognition of rights to organize.
  8. Nested enterprises (for larger-scale resources).

These principles provide the empirical foundation for the BioConomy’s approach to commons governance at bioregional scale. Will Ruddick’s Commitment Pooling work at Grassroots Economics operationalizes Ostrom’s principles in the context of community currencies, a connection Ruddick has explored publicly under the heading “Ostrom’s Law in Action.”
