The paper proposes a game of weighted network formation in which each agent has a limited resource to form links of …, uniquely predicts the equilibrium values of each agent's network investment and utility level, as well as the ratio of any two …

emerge at equilibrium. We define the notion of coalitional network to represent a network and a coalition structure, where … the network specifies the nature of the relationship each individual has with his coalition members and with individuals … contractual stability which requires that any change made to the coalitional network needs the consent of both the deviating …

We consider a generalization of the Minimum Cost Spanning Tree (MCST) model dubbed the Minimum Cost Connection Network … (MCCN) model, where network users have connection demands in the form of a pair of target nodes they want connected directly …, or indirectly. Given a network which satisfies all connection demands at minimum cost, the problem consists of allocating …

I model people in a coordination game who use a communication network to tell each other their willingness to … or "stages": "initial adopters", then "followers", and so on down to "late adopters". A communication network helps …

We consider bargaining in a bipartite network of buyers and sellers, who can only trade with the limited number of … authorities. We perform an experimental test of a graph-theoretic model that allows us to decompose any two-sided network into …

We present a model of directed communication network with endogenous link strength. Agents are endowed with a fixed …

The paper examines the formation of free trade agreements as a network formation game. We consider a three … either unionized or non-unionized), the global free trade network is both the unique pairwise stable network and the uniquee … efficient network. If some countries are unionized while others are non-unionized, other networks apart from the global free …

Thus, any network outside the 1/2 -pairwise stable set must be considered as a non-robust network. We also … show that the 1/2 -pairwise stable set can contain no pairwise stable network and we provide examples where a set of …

This paper applies for the first time power index analysis to the famous Krackhardt’s kite social network by imposing a … weighted voting game on the given network structure.
