根据新近出版的著作《Gouged: The End of a Fair Price》，作者Lindsay Owens详细剖析了企业如何利用动态定价、算法定价和个性化定价等技术手段进行价格操纵，从而大幅削减消费者剩余1。该书通过分析从航空业联合定价到房地产租赁算法、再到打车应用等多个行业案例，论证了市场集中化和协调性提价对消费者造成的伤害1。
Instacart的研究数据显示，约75%的商品在完全相同的购物篮中因消费者不同而产生差异定价1。在房地产领域，RealPage的YieldStar算法曾通过ATPCO方案在1988-1992年间使消费者损失近20亿美元1。打车领域同样存在类似现象——Uber在2022年推出"预付定价"后，司机的提成率从32%上升至42%（2024年底）1，英国牛津经济学家的研究也显示该公司在英国的提成率从25%跃升至29%1。
针对这一现象，Owens在其著作中建议实施"购物者权利法案"，包括禁止算法定价、限制动态定价每日一次、禁止监视定价等措施1。Owens关于价格掠夺的言论曾引发《纽约时报》评论文章，其2025年白皮书则触发了特朗普政府FTC的调查1。
Lindsay Owens' new book "Gouged: The End of a Fair Price" exposes how corporations use sophisticated pricing technologies to extract consumer surplus through dynamic pricing, algorithmic pricing, and personalized pricing schemes 1. The work examines multiple real-world cases, including ATPCO's airline pricing coordination, RealPage's YieldStar algorithm for rental housing, and Uber's upfront pricing model, to demonstrate how market concentration and coordinated price increases harm consumers 1.
The book presents striking evidence of pricing disparities in modern markets. Research on Instacart revealed that approximately 75% of products in identical shopping baskets are priced differently depending on the consumer 1. RealPage's YieldStar algorithm is documented to have cost consumers nearly two billion dollars between 1988 and 1992 through the ATPCO pricing scheme 1. Since Uber introduced upfront pricing in 2022, the driver take rate increased from 32% to 42% by the end of 2024 1. Research by Oxford economists found that Uber's take rate in the United Kingdom surged from 25% to 29% 1.
To address these practices, Owens proposes a "Shopper Bill of Rights" that would prohibit algorithmic pricing, limit dynamic pricing adjustments to once per day, and ban surveillance-based pricing strategies 1. The attention to pricing manipulation intensified after Owens' 2022 Twitter post about price gouging prompted a New York Times commentary, and a 2025 white paper triggered an investigation by the Trump administration's FTC 1.
