价格异质性作为异质性需求的来源
Price Heterogeneity as a Source of Heterogeneous Demand
AI总结：
本文研究价格异质性如何导致需求异质性，证明在消费者面临异质性价格且价格分布稳定时，该模型等价于无异质性价格的异质性偏好/随机效用模型。
摘要：
我们探讨了异质性价格作为异质性或随机需求来源的可能性。异质性价格可能源于消费者之间实际价格差异，或消费者对价格的不同（错误）感知。我们的主要结果如下：如果异质性价格在消费者中的分布在观察中（某种意义上）稳定，那么消费者具有共同效用函数但面临异质性价格的模型，与（无价格异质性的）异质性偏好/随机效用模型具有完全相同的含义。
英文摘要：
We explore heterogeneous prices as a source of heterogeneous or stochastic demand. Heterogeneous prices could arise either because there is actual price variation among consumers or because consumers (mis)perceive prices differently. Our main result says the following: if heterogeneous prices have a distribution among consumers that is (in a sense) stable across observations, then a model where consumers have a common utility function but face heterogeneous prices has precisely the same implications as a heterogeneous preference/random utility model (with no price heterogeneity).
