'Surveillance Pricing' Under Scrutiny
California's Attorney General is reportedly probing the practice of "surveillance pricing," where retailers use customer data profiles to charge different prices for the same items. One analysis noted that services like Instacart can have price variances up to 23% for identical products based on a user's hidden profile. The practice highlights growing concerns over how personalization algorithms are used in e-commerce.
The California Attorney General's investigation centers on whether surveillance pricing violates the California Consumer Privacy Act (CCPA). The key issue is the "purpose limitation" principle, which restricts companies from using personal data in ways that go beyond a consumer's reasonable expectations. Attorney General Rob Bonta's office is formally asking retail, grocery, and hotel businesses for information on how they use personal data to set prices. This isn't just a state-level concern; the Federal Trade Commission (FTC) is also actively probing these AI-driven pricing tactics. Historically, the Robinson-Patman Act of 1936 was enacted to prevent price discrimination that harms competition, though its application to digital services versus tangible goods remains a complex legal question. This form of pricing, technically called first-degree price discrimination, aims to charge each customer the maximum they are willing to pay. Algorithms analyze a vast trove of data points—including browsing history, purchase patterns, location, and even mouse movements—to build a profile and predict a user's price sensitivity. While the Instacart case brought this issue to light recently, the practice has been documented for over a decade. A 2012 Wall Street Journal investigation revealed that retailers like Staples and Home Depot were showing different prices to users based on factors like their proximity to a competitor's physical store. The Instacart pricing experiments were powered by an AI tool from Eversight, a company Instacart acquired in 2022. An investigation by Consumer Reports and Groundwork Collaborative found these tests could alter a family's annual grocery bill by an estimated $1,200. Following the report, Instacart announced it would end the price-testing service. Economists note that personalized pricing can create winners and losers. While some price-sensitive shoppers might receive lower prices, consumers who show a strong preference for a specific product often end up paying more. Research also suggests that competing pricing algorithms can learn to tacitly collude, leading to higher prices for all consumers over time. The concept of a fixed price for every customer is a relatively modern invention. The price tag was popularized in the 1870s by retailers who argued that a universal, transparent price was more fair and efficient than the constant haggling that was common practice before the Industrial Revolution.
