cartel

a group of firms acting in unison

oligopoly

a market structure in which only a few sellers offer similar or identical products Oligopolists maximize their total profits by forming a cartel and acting like a monopolist. Yet, if oligopolists make decisions about production levels individually, the result is a greater quantity and a lower price than under the monopoly outcome. The larger the number of firms in the oligopoly, the closer the quantity and price will be to the levels that would prevail under perfect competition.

prisoners' dilemma

a particular "game" between two captured prisoners that illustrates why cooperation is difficult to maintain even when it is mutually beneficial The prisoners' dilemma shows that self-interest can prevent people from maintaining cooperation, even when cooperation is in their mutual interest. The logic of the prisoners' dilemma applies in many situations, including arms races, common-resource problems, and oligopolies.

Nash equilibrium

a situation in which economic actors interacting with one another each choose their best strategy given the strategies that all the other actors have chosen

The prisoners' dilemma is a two-person game illustrating that the cooperative outcome could be worse for both people than the Nash equilibrium. even if the cooperative outcome is better than the Nash equilibrium for one person, it might be worse for the other. even if cooperation is better than the Nash equilibrium, each person might have an incentive not to cooperate. rational, self-interested individuals will naturally avoid the Nash equilibrium because it is worse for both of them.

even if cooperation is better than the Nash equilibrium, each person might have an incentive not to cooperate.

If an oligopolistic industry organizes itself as a cooperative cartel, it will produce a quantity of output that is______ the competitive level and______ the monopoly level. less than, more than more than, less than less than, equal to equal to, more than

If an oligopoly does not cooperate and each firm chooses its own quantity, the industry will produce a quantity of output that is______ the competitive level and_____ the monopoly level. less than, more than more than, less than less than, equal to equal to, more than
