OLIGOPOLISTIC BEHAVIOR: Oligopolistic industries are nothing if not diverse. Some sell identical products, others differentiated products. Some have three or four firms of nearly equal size, others have one large dominate firm (a clear industry leader) and a handful of smaller firms (that follow the leader). Whatever products they may sell, and however they may be organized, 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 the competitors customers using incentives other than prices (nonprice competition), and when they get tired of competing with their competitors they are inclined to cooperate either legally (mergers) or illegally (collusion).

Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
