IMPLICIT OPPORTUNITY COST: An opportunity cost that does NOT involve a money payment or a market transaction. This should be contrasted with explicit cost that DOES involve a money payment or a market transaction. The common misconception among non-economists out there in the real world is that the term "cost" is synonymous with the term "payment," that is, all costs are explicit costs, to be a cost you have to give up some money. Well, I'm here to tell you that this isn't true. Cost is opportunity cost. It's the satisfaction NOT received from activities NOT pursued. It's the value of foregone production. And not all opportunity costs involve a money payment.

OLIGOPOLY, BEHAVIOR

Oligopolistic industries share several behavioral tendencies, including: (1) interdependence, (2) rigid prices, (3) nonprice competition, (4) mergers, and (5) collusion. In other words, each oligopolistic firm keeps a close eye on the decisions made by other firms in the industry (interdependence), are reluctant to change prices (rigid prices), but instead try to attract customers from the competition using incentives other than prices (nonprice competition), and when they get tired of competing with their competitors they are inclined to cooperate formally and legally (mergers) or informally and illegally (collusion).
