My research studies how information environments and pricing in consumer markets affect what consumers learn, which products and firms they discover and choose, and who benefits. My work ranges from reviews, disclosures, advertising, and search on digital platforms to pricing and consumer choice in health-related markets. My broader goal is to clarify which market design choices influence consumer behavior, how firms respond, and how the resulting market outcomes affect consumer welfare and the distribution of benefits.
