Term game theory Definition: An analysis that illustrates how choices between two plays affect the outcome of a "game." Game theory is commonly used in economics to illustrate interdependent decision-making among oligopoly firms. It illustrates that one firm makes a decision based on the decision expected from the other firm. One key conclusion from the game theory analysis is that firms often make decisions that are "second best" or the "lesser of two evils." The classic example of such a decision is the prisoners' dilemma, in which two prisoners both confess to a crime to avoid harsher punishment when not confessing would avoid any punishment.
