In this paper we examine the role played by heterogeneity in the popular “connections model” of Jackson andWolinsky (1996). We prove that under heterogeneity in values or decay involving only two degrees of freedom, all networks can supported as Nash. Moreover, we show that Nash networks may...

We study the formation of multilayer networks where payoffs are determined by the degrees in each network and explore distinct network relationships by allowing for inter-network and intra-network spillovers through five properties: supermodularity and submodularity for internetwork spillovers,...

We introduce a price oligopoly model with informed and uninformed consumers, thus creating a new channel of influence for collaborative R&D. Firms can establish pair-wise collaborative research links with other firms to lower production costs. Informed consumers buy from the lowest cost firms...

We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that...

In this paper we examine efficient networks in network formation games with global spillovers that satisfy convexity and sub-modularity properties. Unlike the previous literature we impose these properties on individual payoff functions. We establish that efficient networks of this class of...

In this note, we extend the Goyal and Joshi's model of network of collaboration in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We also present some results on efficient networks

We study the formation of mutual insurance networks in a model where every agent who obtains more resources gives a fixed amount of resources to all agents who have obtained less resources. The low resource agent must be directly linked to the high resource agent to receive this transfer. We...

This paper examines a recurrent oligopoly game, where firms imitate the most successful behaviors in their memory. We intend to characterize stochastically stable states. Several models are considered which differ in the specification of players? memory. We note that the specification of memory...
