Explanation:

A cartel is an association of manufacturers or suppliers with the purpose of maintaining prices at a high level and restricting competition.A cartel is a group of apparently independent producers whose goal is to increase their collective profits by means of price fixing, limiting supply, or other restrictive practices. Cartels typically control selling prices, but some are organized to force down the prices of purchased inputs. Antitrust laws attempt to deter or forbid cartels. A single entity that holds a monopoly by this definition cannot be a cartel, though it may be guilty of abusing said monopoly in other ways. Cartels usually arise in oligopolies -- industries with small number of sellers -- and usually involve homogeneous products.
