向竞争对手出售数据
Selling Data to a Competitor
摘要：
我们研究向竞争对手出售数据的成本和收益。虽然出售所有消费者的数据可能会减少公司的总利润，但存在其他销售机制-其中只有一些消费者的数据被出售-使两家公司都更好。我们确定了利润最大化的机制，并表明，企业的利益是以消费者为代价的。然后，我们构建帕累托改进机制，其中每个消费者的福利，以及双方的利润，增加。最后，我们表明，消费者选择加入可以作为一种工具，诱导企业选择帕累托改进机制的利润最大化。
英文摘要：
We study the costs and benefits of selling data to a competitor. Although selling all consumers' data may decrease total firm profits, there exist other selling mechanisms -- in which only some consumers' data is sold -- that render both firms better off. We identify the profit-maximizing mechanism, and show that the benefit to firms comes at a cost to consumers. We then construct Pareto-improving mechanisms, in which each consumers' welfare, as well as both firms' profits, increase. Finally, we show that consumer opt-in can serve as an instrument to induce firms to choose a Pareto-improving mechanism over a profit-maximizing one.
