内容摘要：Many cartels exist in supply chains with powerful buyers. These buyers have the incentive and information to report the cartel to the antitrust authorities or sue the cartel members. Therefore, successful upstream collusions not only need to prevent the collusive members to deviate, but also has to compensate the downstream firms. Using repeat game theory, this paper studies the stability of upstream collusion, taking into account the downstream compensation. Different from the standard collusion theory, the relationship between cartel incidence and market concentration is likely to be non-monotonic, or it is the inverted U-shape.
