Tragedy of the Commons and Shared Resource Systems
Tragedy of the Commons and Shared Resource Systems explains how shared resources become depleted when individual actors benefit from use while the costs of overuse are distributed across the wider system. The article shows that commons are not limited to pastures, fisheries, forests, or water, but also include the atmosphere, public trust, infrastructure capacity, attention, information quality, institutional legitimacy, workforce capacity, open-source software, and ecological resilience. It distinguishes governed commons from unmanaged open access, emphasizing trust, fair rules, monitoring, sanctions, participation, restoration, and legitimacy. Through examples from public health, infrastructure, organizations, education, artificial intelligence, climate systems, economics, and public administration, the article examines how private gain and shared cost create depletion. Readers gain a practical method for diagnosing commons systems, identifying users, tracking resource stocks, analyzing unequal responsibility, and designing stewardship institutions.
