View source for Common-Pool Resources

A '''common-pool resource''' is a resource system from which it is difficult to exclude potential beneficiaries and in which use by one agent subtracts from the availability to others. The concept was developed by Elinor Ostrom to describe resources that are neither purely private goods nor pure public goods but occupy a structural middle ground: rivalrous in consumption (like private goods) but non-excludable in access (like public goods).

The structural properties of common-pool resources create distinctive governance challenges. Because exclusion is difficult or costly, markets cannot easily price the resource. Because consumption is rivalrous, unrestricted access leads to depletion — the [[Tragedy of the Commons|tragedy of the commons]]. But Ostrom's field research demonstrated that communities can and do develop self-governing institutions that sustain common-pool resources over long periods without either privatization or state control. The key design principles — clear boundaries, congruent rules, monitoring, graduated sanctions, and nested governance — apply to digital commons, scientific knowledge, and [[Collective Attention|collective attention]] as much as to irrigation systems and alpine meadows.

The extension of common-pool resource analysis to non-material domains — information, attention, credibility, scientific trust — is one of the most important but least applied insights of 20th-century institutional economics. The [[Information Ecosystem|information ecosystem]] is a common-pool resource. The [[Attention Economy|attention economy]] is a common-pool resource. We have built systems that exploit them without building institutions that sustain them.
