This paper develops an analytical model of contagion in financial networks with arbitrary structure. We explore how the probability and potential impact of contagion is influenced by aggregate and idiosyncratic shocks, changes in network structure and asset market liquidity. Our findings suggest that financial systems exhibit a robust-yet-fragile tendency: while the probability of contagion may be low, the effects can be extremely widespread when problems occur. And we suggest why the… Expand

Contagion in Financial Networks
The recent financial crisis has prompted much new research on the interconnectedness of the modern financial system and the extent to which it contributes to systemic fragility. Network connectionsExpand
FINANCIAL CONTAGION DYNAMICS IN RANDOM INTERBANK NETWORKS
The purpose of this study is to assess the resilience of financial systems to exogenous shocks using techniques drawn from the theory of complex networks. We investigate by means of Monte CarloExpand
Inhomogeneous Financial Networks and Contagious Links
We propose a framework for testing the possibility of large cascades in financial networks. This framework accommodates a variety of specifications for the probabilities of emergence of “contagiousExpand
How Likely Is Contagion in Financial Networks?
Interconnections among financial institutions create potential channels for contagion and amplification of shocks to the financial system. We estimate the extent to which interconnections increaseExpand
Financial Contagion and Network Analysis
Network models of interbank exposures allow the mapping of the complex web of financial linkages among many institutions and address issues of system stability and contagion risk. Although existingExpand
Simulating financial contagion dynamics in random interbank networks
TLDR
This study investigates by means of Monte Carlo simulations the fragility of several network topologies using a simple default model of contagion applied on interbank networks of varying sizes, and analyzes the interplay of several crucial drivers of interbank contagion. Expand
Complexity, concentration and contagion
This paper develops a network model of interbank lending in which unsecured claims, repo activity and shocks to the haircuts applied to collateral assume centre stage. We show how systemic liquidityExpand

Contagion in Heterogeneous Financial Networks
TLDR
It is found that when banks redistribute assets following an initial mild contagion it increases the stability, on average, of the system to subsequent shocks originating at weakened banks. Expand
