Contagion in networks
Downloadable! This paper provides an introduction to the literature on financial contagion in networks. In the first part, we consider contagion via transmission of shocks, i.e. an abrupt drop in the flow of revenue to one firm, which affects other firms connected to it through financial linkages. We then study informational contagion, by which we mean the process whereby a …Definition 1. Given a network configuration σ, a liquidity shock of size θ at bank i, d ( j; σ, θ, i) is the least number of steps a shock can transmit via a directed path in the network from bank i to bank j, that is, the geodesic path from bank j to bank i through insolvent banks. By definition, d ( i; σ, θ, i ) ≡ 0.

in the network theory literature, and then consider empirical studies that investigate the relationship between centrality measures and the inherent vulnerability of the network to contagion. We argue that thus far the empirical work has not produced a compelling link between traditional network measures and financial stability.4 Some studies analyse financial contagion using random or fat-tailed networks. For instance, Gai and Kapadia (Citation 2010) reveal features of an interbank network exhibiting a robust-yet-fragile property, whereby high connectivity increases risk-sharing and reduces the probability of contagious failure, but when contagion occurs, more links allow the possibility of widespread …Fig. 1.

Final remarks. In this paper, we have investigated the stability and efficiency properties of networks where agents derive benefits only from other agents linked directly with them but suffer losses when any other agent who is either directly or indirectly connected to them is hit by a shock.

Our model of contagion relaxes the assumption that actors can only transition from an inactive to an active state. We also allow the effects of each activation to vary over time to the extent that they coevolve with the contagion dynamics taking place in the rest of the network. blox fruits usopp hatcongressional bill templatediamond joseline cabaret ig Abstract.

This paper studies intertemporal asset pricing in network economies when distress shocks can propagate through the network, similarly to epidemic outbreaks. Two classes of equilibria exist. In the first, idiosyncratic shocks are diversifiable and do not affect valuations; the consumption capital asset pricing model applies.
