OPEC, or the Organization of the Petroleum Exporting Countries, is an intergovernmental organization founded in 1960 to coordinate and unify petroleum policies among its member countries. By managing oil production levels, OPEC aims to secure fair prices for oil producers and a stable supply for consumers. The group operates in a manner that often reflects the principles of cooperation and competition similar to the Prisoner's Dilemma, where member countries must decide whether to act in their self-interest or to cooperate for collective benefit.
