Most-Favored-Customer Pricing and Tacit Collusion
研究最惠顾客定价政策在动态双寡头价格竞争模型中如何促进企业默契合谋，通过降低降价激励使双方维持高价并提高利润。
This article examines the role of the most-favored-customer pricing policy as a practice facilitating coordination in a dynamic model of price-setting duopoly. This policy is a promise by a firm that if it later lowers price, it will rebate to current customers the difference between the price they pay now and the lower future price. By reducing each firm's incentive to reduce price, the policy enables both firms to offer higher prices and to enjoy higher profits. Consequently, at least one firm offers the policy in equilibrium. We illustrate these general results in an example.
