What happens when all individuals share a limited resource, hurting the collective as a whole?

• A. Tragedy of the commons
• B. Prisoners dilemma
• C. Public goods
• D. Private goods

Answer: (A)

When a resource is shared and limited, each person has an incentive to use as much as possible now to maximize personal gain, which leads to overuse and eventual depletion that hurts everyone. This dynamic is the tragedy of the commons. A classic example is a public pasture: every farmer benefits by grazing more animals, but as the herd grows beyond what the pasture can sustain, the grass is depleted and all farmers suffer from a poorer yield later. This concept differs from the others in these ways: the prisoners dilemma focuses on strategic choices between two actors and how cooperation can fail, even when mutual cooperation would be best; public goods are benefits that everyone can access without reducing others’ access, so they aren’t depleted by use; private goods are owned and consumed by individuals, so use doesn’t imply shared depletion in the same way.
