This paper studies the properties of convexity (concavity) and strategic complements (substitutes) in network formation … shown that there always exists a pairwise stable network as long as the utility function of each player satisfies convexity … in own links and strategic complements. For network societies with a profile of utility functions satisfying concavity in …

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing … private information. In all treatments, the (efficient) equilibrium network has a "star" structure. With homogeneous agents …

This paper reports the results of a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the basic Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by … network has a star structure. We find that with homogeneous agents, equilibrium predictions fail completely. In contrast, with …

that the individual's incentives depend on the architecture of the network as well as on the position of the individual … within the network. In particular, when an efficient interaction requires players to mutually cooperate, efficient social …

Suppose that individual payoffs depend on the network connecting them. Consider the following simultaneous move game of … network formation: players announce independently the links they wish to form, and links are formed only under mutual consent …. We provide necessary and sufficient conditions on the network link marginal payoffs such that the set of pairwise stable …

structure of conflictive relations is modeled as a conflict network where opponents are embedded in a local structure of … aggregated equilibrium investment (interpreted as conflict intensity) and underlying network characteristics. The derived results …
