CORE DEFINITION

When multiple individuals share a finite resource (such as a common pasture), each individual, in order to maximize their own benefit, overuses the resource, ultimately leading to its depletion and harming the interests of all.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

It explains the failure of collective action and why government or collective agreements are needed to manage shared resources. Solutions include clarifying property rights, establishing usage rules, implementing punishment mechanisms, or constraining individual behavior through social norms.

Shared resources are non-excludable, and individual rationality (taking more for oneself) leads to collective irrationality (resource depletion). Each user's marginal benefit is private, while marginal costs are shared, incentivizing overuse.
