This paper examines optimal targeting and sequencing strategies in the setup proposed by Ballester et al. (2006). The setup features payoff externalities and strategic complementarity among players, who non-cooperatively determine their contributions. We first analyze a two-stage game in which...

As a common practice, various firms initially make information and access to their products/services scarce within a social network; identifying influential players that facilitate information dissemination emerges as a pivotal step for their success. In this paper, we tackle this problem using...

In this paper, we consider a model with a monopoly firm who sells social goods sequentially to a group of customers in a network. We show that, with symmetric social interactions, the optimal pricing under arbitrary launch sequence is independent of customers' network positions, the launch...

We consider a network model where individuals exert efforts in two types of activities that are interdependent. These activities can be either substitutes or complements. We provide a full characterization of the Nash equilibrium of this game for any network structure. We show, in particular,...

We study pricing strategies of competing firms that sell heterogeneous products to consumers in a social network. Goods are substitutes and there are network externalities between neighboring consumers. We show that there exists a unique subgame-perfect equilibrium where, in the first stage,...
