In the benchmark model of Bala and Goyal (2000) on network formation, the equilibrium network is asymmetric and unfair … impacts the network formation process by increasing the asymmetry of networks but does not decrease the level of fairness nor …

In this paper, we show that a concept of aggregation can hold in large network games with linear best replies. Breaking … compute all Nash equilibria for the special network structure of cograph. A key finding is that a stable Nash equilibrium of … the large network game can be decomposed into a collection of Nash equilibria of subnetwork games. Thereby, we establish a …

In this paper, we show that a concept of aggregation can hold in network games. Breaking up large networks into smaller … provide an application to public goods in networks to show the usefulness of our results. In particular, we highlight network … architectures that cannot prevent free-riding in public good network games. Finally, we show that aggregation enhances the stability …

I look at the equilibrium effects of homophily in network formation games having positive externalities. I show that … very weak preferences for network effects (such as preference for being part of a clique) may result in very high levels of … homophily at equilibrium. I present an empirical procedure that allows an evaluation of the role of network effects on the …

This paper proposes new centrality measures to characterise the 'key class', when agents in a network are sorted into … role-equivalent classes, such that its removal results in an optimal change in the network activity. The notion of role … theoretical applicability. Players in the network engage in a non-cooperative game with local payoff complementarities. We …

This paper develops a framework for analyzing the effect of arbitrary changes to network structure in linear …-quadratic games on networks. Changes to network structure which increase total activity and total utility are studied for the case of … centrality which counts the total length of walks from a node.Two optimal network design problems are then considered. Total …

many well-known results from the contest literature can be obtained by varying the structure of the network. Our framework …

I present a behavioural model of network formation with positive network externalities in which individuals have …

We consider an incomplete information network game in which agents’ information is restricted only to the identity of … walks they have in the network. Our model clearly demonstrates how asymmetric information based on network position and the … identity of agents affect strategic behavior in such network games. We also characterize agent behavior in equilibria under …

We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network … structure. We discuss, in particular, the impact of the structure of the network on individuals' behaviors. We focus on game …
