Personalized Pricing When Consumers Can Purchase Multiple Items*
研究了在Hotelling双寡头模型中，当消费者可以从两家企业购买商品时，竞争性个性化定价的影响。发现当消费者购买第二件商品的额外效用适中时，个性化定价对消费者和企业都有利；但当额外效用较大时，则损害消费者利益而有利于企业。
We study the impact of competitive personalized pricing in a Hotelling duopoly model where consumers can purchase from both firms. We show that the impact crucially depends on the magnitude of the additional utility from consuming the second product. Compared with uniform pricing, personalized pricing benefits both consumers and firms when the additional utility is moderate; but it harms consumers while benefiting firms when the additional utility is large. These results contrast with the existing research on competitive personalized pricing, which assumes that consumers purchase one product only.
