Title: Good Data and Bad Data: The Welfare Effects of Price Discrimination

Abstract: The rise of big data technologies has revived the longstanding debate on who reaps the economic benefit of more information, firms, or consumers. We study the welfare consequences of monopoly pricing across all possible segmentations of a given family of demand curves. We provide necessary and sufficient conditions on this family of demand curves under which the monopolist's use of information never always depress versus always improve consumer welfare despite the ensuing price discrimination. Our classification provides insights to guide the recent policy discussion in use of consumer data and sheds light on the type of information that can be allowed in price discrimination. Joint work with Nima Haghpanah and Ali Shourideh.
