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...

Two types of intervention are commonly implemented in networks: characteristic intervention which influences individuals' intrinsic incentives, and structural intervention which targets at the social links among individuals. In this paper we provide a general framework to evaluate the distinct...

Network-based targeting is valuable in many applications such as diffusion of new technology, product promotion in marketing, among others. Nevertheless, how to quantitatively measure the effectiveness of targeting strategies remains a challenge. This paper studies a class of network games with...

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...

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,...
