    Abstract: 本文參考Montes et al. (2019)產品水平差異化雙佔模型設定,假設市場上僅有一家資訊提供商,並將市場上的消費者分為新消費者與舊消費者。本文假設資訊提供商僅提供舊消費者的資訊,若零售商購買消費者資訊,則可以針對舊的消費者進行差別取價;並假設共有三種情況,分別為資訊提供商未販售消費者資訊、資訊提供商僅販售給資訊給一家零售商與資訊提供商同時販售資訊給兩家零售商。上述設定下,本文加入網絡效果(Network Effect),進而探討網絡效果對於零售商與消費者的是否有正面效益,最後也會探討消費者資訊價值是否會因為網絡效果而有所變化。
    結果發現在網絡效果相對小時,其結論與Montes et al. (2019)相同,皆是資訊提供商只販售消費者資訊給一家零售商的權利金最高,且本文發現雖然網絡效果可以使消費者增加產品的附加價值,並願意付出更高的價格,但零售商卻也因為更想爭取消費者而削價得更加厲害,並使利潤反而低於無網絡效果時,最終造成不論兩家零售商是否有消費者資訊,網絡效果對於零售商皆為負面效果大於正面效果,使得消費者因為零售商互相競爭而得利。然而在網絡效果極大時,儘管只有兩家零售商皆有消費者資訊的情況符合本文的競爭均衡,但與Montes et al. (2019)不同,網絡效果能降低零售商在新消費者間的競爭程度,使得零售商在基礎價格訂定更高的定價,並得出零售商與消費者皆可以從網絡效果中得利。
    This passage discusses the setting of horizontal product differentiation duopoly model, referencing Montes et al. (2019). It is assumed that there is only one information provider in the market and divides consumers into new consumers and old consumers. The paper assumes that the information provider only offers information to old consumers. If a retailer purchases consumer information, they can engage in price discrimination based on the old consumers. The paper considers three scenarios: the information provider does not sell consumer information, the information provider sells information to only one retailer, and the information provider sells information to two retailers simultaneously.Under the above settings, the paper incorporates network effects and examines whether network effects have positive benefits for retailers and consumers. It also explores whether the value of consumer information changes due to network effects.
    The results reveal that when network effects are relatively small, the conclusions align with Montes et al. (2019). The highest licensing fee is obtained when the information provider sells consumer information exclusively to one retailer. The paper finds that although network effects can increase the additional value of the product for consumers and make them willing to pay a higher price, retailers become more aggressive in price competition to attract consumers, resulting in lower profits compared to the scenario without network effects. Ultimately, regardless of whether the two retailers have consumer information, the negative effects of network effects on retailers outweigh the positive effects, benefiting consumers due to the intense competition among retailers.However, when network effects are substantial, although the case where only two retailers have consumer information conforms to the competitive equilibrium described in this paper, it differs from Montes et al. (2019). Network effects can reduce the level of competition among retailers for new consumers, allowing retailers to set higher base prices and benefit both retailers and consumers from the network effects.
