It describes the properties of a collusive outcome in terms of the setting of price and a market allocation, monitoring of agreements with respect to price but more importantly sales, punishment methods for enforcing an agreement and also the use of buy-backs to compensate cartel members, methods for responding to external disruptions from non-cartel sup- pliers and handling over-zealous sales representatives, and operational procedures in terms of the frequency of meetings and the cartel’s organizational structure.cartelsmicroeconomicsBusinessEconomicsPublic Affairs, Public Policy and Public AdministrationArticle
