Market Segmentation and Product Steering
研究了垄断卖家拥有多种产品时，通过市场细分引导消费者选择，并刻画了生产者与消费者剩余的组合，发现更多隐私保护的市场细分能带来更高的消费者剩余。
A monopolistic seller possesses an inventory containing distinct products, each consumer wishes to buy a single product, and the seller can steer consumers' choices. We fully characterize the producer-consumer surplus pairs induced by market segmentation when the number of products is large. The same characterization holds if the seller cannot price discriminate. We also investigate the relationship between consumer surplus, social welfare, and consumer privacy. Along the Pareto frontier, points with greater consumer surplus can be reached by market segmentations that afford more privacy.
