What role does a price leader play in tacit collusion?

A price leader plays a crucial role in tacit collusion by setting standards for acceptable prices within a market. In scenarios where firms in an oligopolistic market recognize mutual interdependence, a price leader establishes a price point that other competitors are likely to follow to avoid price wars and maintain stable profit margins. This behavior reflects an unspoken agreement among firms to adhere to this price, thereby minimizing the risks associated with aggressive competition.

In tacit collusion, the actions of the price leader signal to other firms the acceptable pricing strategy without any formal agreement. By adhering to this price leader's standard, firms can sustain a cooperative atmosphere, resulting in overall market stability. This approach effectively enables firms to cooperate on pricing without direct communication or formal arrangements, as they implicitly acknowledge the price leader's role in guiding market behavior.
