We investigate how information goods are priced and diffused over links in a network. A new equivalence relation between nodes captures the effects of network architecture and locations of sellers on the division of profits, and characterizes the topology of competing (and potentially...

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,...

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

This paper proposes a model of voting competitions (political campaigns and strategic lobbying) where voters are influenced by the opinion of their neighbors on a social network. In the unique pure strategy nash equilibrium, resources are targeted toward individuals with an influential position...

We provide an analytical approach to the problem of influence maximization in a social network when two players compete by means of dynamic targeting strategies. We formulate the problem as a two-player zero-sum stochastic game. We prove the existence of the uniform value: if the players are...

Whereas technical standards and Standard Setting Organizations (SSOs) are omnipresent and essential to mass production and mass communications, relatively little is formally known about the propensity of firms to belong to certain SSOs. This paper uses a social network analysis technique to...

Reciprocal customers may disproportionately improve the performance of markets for experience goods. Reciprocal customers reward (punish) firms for providing good (bad) quality by upholding (terminating) the customer relation. This may induce firms to provide good quality which, in turn, may...

In this article, we analyze the dynamic competition between two platform firms (A&B) in two-sided markets with network externalities. In Period 1, platform A or B wins the contest in a first stage and can serve the two-sided market monopolistically in a second stage. In Period 2, the two...

This paper investigates the effects of changes in retail market concentration when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between upstream and downstream firms which allows for general forms of demand and retail competition. Whether...

A vertical merger model represents a complex system built on (i) a network of e.g., upstream manufacturers and downstream retailers (ii) who bargain bilaterally in the presence of externalities (iii) created by competition between downstream retailers (iv) facing a consumer demand surface. We...
