Market Segmentation Through Information

Research Seminars

An information designer has precise information about consumers' preferences over products sold by oligopolists. The designer chooses what information to reveal to differentiated firms who, then, compete on price by making personalized offers. The authors ask what market outcomes the designer can achieve. The information designer is a metaphor for an internet platform who collects data about users and sells it to firms who can, in turn, target discounts and promotions towards different consumers. Their analysis provides new benchmarks demonstrating the power that users' data can endow internet platforms with. These benchmarks speak directly to current regulatory debates.
