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

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 …

Interconnected banks are prone to the propagation of negative shocks. In a network with banks borrowing from each other …

network properties are presented. Motivated by the behavior of some nodes with histories of large transactions, we propose a … a source and destination of a node. Using this Flow Index, we study the global structure of the XRP network and …

We study the optimal welfare maximising intervention in a multiple activity network model taking into account both … within-activity network spillovers and cross-activity interdependences. We analyse the effects of a restriction in the … terms of the eigenspaces of the network matrix, and provide a simple choice of intervention for the planner that achieves an …

Most literature in strategic network formation shows that there is a substantial tension between stability and … (2000a) and De Jaegher and Kamphorst (2015). Specifically, I show that every link receiver in a Nash network serves as an …

We consider network games in which players simultaneously form partnerships and choose actions. Players are …. We find that, despite the symmetry and simplicity of the setting, quite irregular network structures can arise in …

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 …

particular, if the linking costs are not too low and not too high, at least one such network is pairwise stable. Moreover, in … explanation for many core-periphery structures observed in real life social networks. -- Network Formation ; Heterogeneity …
