摘要翻译：
我们考虑了一个具有搜索摩擦的市场中的寡头竞争模型，在该模型中，具有未知质量的产品的竞争公司广告消费者访问将收集到多少信息。我们刻画了这个博弈的唯一对称均衡，由于吸引和说服的反向激励，每个企业产生一个与企业实现的有效价值成线性关系的收益函数。如果产品的预期质量足够高（或竞争足够激烈），这就对应于完整的信息--搜索摩擦导致信息提供的最佳水平。如果不是，这就相当于信息分散--企业在信号上随机化。如果不存在吸引激励（由于隐藏信息或无成本搜索），企业披露的信息较少，信息分散就不会出现。

英文摘要：
  We consider a model of oligopolistic competition in a market with search frictions, in which competing firms with products of unknown quality advertise how much information a consumer's visit will glean. We characterize the unique symmetric equilibrium of this game, which, due to the countervailing incentives of attraction and persuasion, generates a payoff function for each firm that is linear in the firm's realized effective value. If the expected quality of the products is sufficiently high (or competition is sufficiently fierce), this corresponds to full information--search frictions beget the first-best level of information provision. If not, this corresponds to information dispersion--firms randomize over signals. If the attraction incentive is absent (due to hidden information or costless search), firms reveal less information and information dispersion does not arise.
