Optimal connectivity for a large financial network

Abstract: Abstract. We investigate network formation for a set of financial institutions represented as nodes.Linkages are source of income, and at the same time they bear the risk of contagion. The optimal connectivity of the nodes results from a game, in which the risk of contagion depends on the choices of all nodes in the system. Our financial network model can be interpreted as a set of banks connected through funding relations, in which a node's threshold to contagion is represented by its external funding capacit… Show more

“…We are now ready to define the nodes' reward. In the case without growth, the analysis of the optimal connectivity is treated in [20]. For its tractability, we keep the same reward definition here and we analyze the effect of growth on the network in equilibrium.…”
