Monopoly and Olygopoly

MONOPOLY A monopoly exists when a specific person or enterprise is the only supplier of a particular commodity (this contrasts with amonopsony which relates to a single entity's control of a market to purchase a good or service, and with oligopoly which consists of a few entities dominating an industry) Monopolies are thus characterized by a lack of economic competition to produce the good or service and a lack of viable substitute goods.

Likewise, a monopoly should be distinguished from a cartel (a form of oligopoly), in which several providers act together to coordinate services, prices or sale of goods.
