摘要翻译：
本文研究竞争对手之间的合作数据共享，以预测消费者的口味。我们设计了最优的数据共享方案，既适用于只与彼此竞争的情况，也适用于与亚马逊竞争的情况--亚马逊是一家拥有更多、更好数据的公司。我们证明了简单的方案--概率地导致竞争对手之间完全数据共享或数据从一个竞争对手完全转移到另一个竞争对手的阈值规则--要么是最优的，要么是近似最优的，这取决于信息结构的性质。我们还提供了当企业面临更强的外部竞争时共享更多数据的条件，并描述了该结论被推翻的情况。

英文摘要：
  This paper studies cooperative data-sharing between competitors vying to predict a consumer's tastes. We design optimal data-sharing schemes both for when they compete only with each other, and for when they additionally compete with an Amazon -- a company with more, better data. We show that simple schemes -- threshold rules that probabilistically induce either full data-sharing between competitors, or the full transfer of data from one competitor to another -- are either optimal or approximately optimal, depending on properties of the information structure. We also provide conditions under which firms share more data when they face stronger outside competition, and describe situations in which this conclusion is reversed.
