The increase in the information that firms can obtain about the interactions and influences of their consumers motivates two important questions: How does the pricing strategy of a firm reacts to detailed information on consumers' externalities? Is the availability and use of such information beneficial or detrimental for consumer welfare? We study these questions in a model where a monopoly sells a network good and may price discriminate using information on consumers' influences and/or on consumers' susceptibilities to influence. Our framework incorporates a rich set of market products, including goods characterized by global and local network effects. The optimal pricing takes a simple form, which entails a price discount for the influence of consumers and a price premium for their susceptibility; both of these components are a function of the pattern of externalities across consumers. We can determine under which conditions, relative to uniform price, consumer surplus increases. We provide a full characterization of the value of network information for the monopolist.
