Tragedy of the Commons

Mental models

A shared resource with private incentives to consume it gets depleted, because each user captures the whole benefit and bears a fraction of the cost. Ostrom's work showed the outcome is not inevitable where communities can monitor and sanction each other. In markets it explains overfished trades, degraded industry economics and every race to the bottom on underwriting standards.
