论文摘要
我们研究公司之间数据共享对价格，利润和消费者福利的影响。尽管由于竞争的增加，消费者数据的不加区分分享降低了公司的利润，但选择性共享可能是有益的。我们表明，有一些数据共享机制严格占据了帕累托的改善，同时增加了公司的利润和消费者福利。在帕累托改造机制的类别中，我们确定一种使公司利润最大化的一种，而一种使消费者福利最大化。
We study the effects of data sharing between firms on prices, profits, and consumer welfare. Although indiscriminate sharing of consumer data decreases firm profits due to the subsequent increase in competition, selective sharing can be beneficial. We show that there are data-sharing mechanisms that are strictly Pareto-improving, simultaneously increasing firm profits and consumer welfare. Within the class of Pareto-improving mechanisms, we identify one that maximizes firm profits and one that maximizes consumer welfare.
