Libai's research focusses on the intersection of Customer Profitability Analysis, the Diffusion of innovations, and the impact analysis of the social influence of customers. His research shows the role of Customer equity, the sum of the individual lifetime value of customers, as one of the most important business measures of the firm and a key parameter to any customer-related resource allocation. Libai's research focuses on customer social value, ways to assess it, and how it can influence managerial decision-making. His work has also examined various ways in which social influence namely word of mouth, network effects, imitation, and social norms (such as fashions) can affect the growth of new products and the profitability of the firm. Some of this work has examined how firms can proactively influence customer word of mouth as part of the marketing mix, for example, through seeding programs that target influencers or by Referral programs. Other work dealt with various issues related to customer profitability particularly in new digital environments, such as models for the monetization of mobile apps, the role of customer retention in the firm's profitability, and the network value products create. Libai is member of the editorial board of several academic journals including Journal of Marketing, International Journal of Research in Marketing, Journal of Service Research, and California Management Review.
