　　摘要: This paper investigates the incentives and effects of competing firms sharing consumers’ personal information in a duopoly market, where two firms sell vertically differentiated products. We derive firms’ pricing strategies and welfares of all parties under different information structures. And we show that only when firm with less competitive advantage has all consumers’ information will sell part of consumers’ personal information to its competitor to maximize the total revenue. The smaller the competitive advantage of the firm, the more personal information of consumers will be sold to their competitors. To maximize the profits of the whole industry and also social welfare, all consumers’ personal information should be owned by the firm with competitive advantage.
