Eigenvector-based centrality measures are among the most popular centrality measures in network science. The underlying idea is intuitive and the mathematical description is extremely simple in the framework of standard, mono-layer networks. Moreover, several efficient computational tools are available for their computation. Moving up in dimensionality, several efforts have been made in the pas...

We define a model of peer effects where the intra-group externality is rooted on the network of bilateral influences in the population, rather than consisting on an average effect. Using game theory, we then map the geometric intricacies of this network structure to the distribution of equilibrium outcomes. Nash equilibrium turns out to be well-described by Bonacich network centrality, used in ...

Many firms try to leverage consumers’ interactions on social platforms as part of their communication strategies. However, information online networks only propagates if it receives attention. This paper proposes a seeding strategy maximize propagation while accounting for competition The theory exchange serves the framework identifying optimal and recommends people that have many friends, who,...

Since it first emerged in the 1930s, SNA has extensively grown across multiple research fields, including physics, biology, and history, among others (Borgatti et al. 2009). In the social sciences, the distinctive contribution of SNA has been to shift the analytical focus from individual characteristics or social categories, which were at the center of classical social science research, to the ...

We study the revenue-optimal pricing strategies of a monopolist selling a divisible good (service) that exhibits positive externalities to consumers embedded in a social network. The positive externalities in our model mean that a consumer's usage level depends directly on the usage of his neighbors in the network. Optimal pricing may therefore involve offering different prices based on consume...

Abstract We investigate the design of revenue-optimal pricing strategies for a monopolist selling a divisible good (service) that exhibits positive externalities to consumers that are embedded in a social network. Specifically, we study how the revenue captures varies with extent of price discrimination and the externalities at play. We first consider a setting where the monopolist can offer in...
