摘要

本文研究了双头垄断中定向广告的福利效应。为此，本文提出了一个博弈论模型，在该模型中，企业可以对其定位技术进行昂贵的投资。结果表明，事前相同的企业在技术博弈的每一个纯战略均衡中都使用不同的技术。如果企业的目标群体是同一群消费者，那么低技术含量的企业可以通过使用更好的技术来增加整体福利。然而，由于企业之间的竞争加剧，这导致行业利润下降。

A model of endogenous targeting in duopoly

The paper investigates welfare effects of targeted advertising in a duopoly. To this end, a game-theoretical model is proposed in which firms can make costly investments in their targeting technology. It can be shown that ex ante identical firms use different technologies in every pure-strategy equilibrium of the technology game. If firms target the same group of consumers, the low-technology firm could increase overall welfare by using a better technology. However, this leads to lower industry profits due to tougher competition among firms.
