论文摘要
我们探索异质价格作为异质或随机需求的来源。可能是因为消费者的实际价格差异，或者是因为消费者（MIS）对价格有所不同，因此可能出现异质价格。我们的主要结果表明以下内容：如果异质价格在消费者之间具有分布（从某种意义上说）在观察中稳定，那么消费者具有共同的效用功能，但面对异质价格的含义与异性偏好/随机效用模型完全相同（没有价格异质）
We explore heterogenous prices as a source of heterogenous or stochastic demand. Heterogenous 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 heterogenous 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 heterogenous prices has precisely the same implications as a heterogenous preference/random utility model (with no price heterogeneity)
