Abstract

We demonstrate the "curse of knowledge" when a monopolist can recognize different consumer groups through their purchase histories which are influenced by its dynamic pricing policies. Under the Markov-perfect equilibrium, after each commitment period, the firm offers a new introductory price so as to attract new customers. More and more market segments are added gradually. Eventually, the whole market is covered. Shortening the commitment period will result in a fall in profit. In contrast, a full-commitment monopolist would choose to stick to uniform pricing, achieving higher profit. Hence, the firm is better off by refraining from collecting customer information. Nous demontrons la "malediction du savoir" lorsqu'un monopoleur peut reconnaitre differents groupes de consommateurs a travers leurs historiques d'achat influences par sa politique de prix dynamique. Sous l'equilibre de Markov-parfait, l'entreprise propose, apres chaque periode d'engagement, un nouveau prix de lancement afin d'attirer de nouveaux clients. De plus en plus de segments de marche sont ajoutes progressivement. Finalement, tout le marche est couvert. La reduction de la periode d'engagement entrainera une baisse des benefices. En revanche, un monopoleur pleinement engage choisirait de s'en tenir a un prix unique, realisant des benefices plus eleves. Par consequent, le monopoleur gagnerait plus de profit s’il pouvait s'engager de ne pas collecter des informations sur les clients.

知识的诅咒:获得客户信息可以减少垄断利润
当垄断者可以通过受其动态定价政策影响的购买历史来识别不同的消费者群体时,我们证明了“知识的诅咒”。在马尔可夫完全均衡下,在每一个承诺期之后,企业都会提供一个新的引入价格,以吸引新的客户。越来越多的细分市场逐渐加入。最终,整个市场都被覆盖了。缩短承诺期将导致利润下降。相反,一个完全承诺的垄断者会选择坚持统一定价,从而获得更高的利润。因此,公司最好避免收集客户信息。noous demontrons ' s malediction du savir '或' unmonopoleur ' ' re re re re re不同群体的共谋者和旅行者的历史影响的政治和动态的价格。Markov-parfait的平衡,企业的提议,preres chque period d'engagement, unnouveau prix de lancement in a 'attirer de nouveaux clients。De + en + De segments De marche sont ajoutes progreses。最后,我要向你证明。减少参与的时间,使其受益的基础更加丰富。在复仇的过程中,非垄断性的满足涉及到选择的选择,这是一种独特的、现实的好处和好处。因此,垄断性的垄断加上利润的增加,将会使“参与人”、“收集者”、“信息收集者”和“客户”之间的关系更加紧密。
