|Cascading processes in complex networks: From systemic risk in banking networks to the collapse of F|
speaker : Frank Schweitzer[ETH Zurich, Switzerland]
date : 2013-11-13
The term systemic risk commonly denotes the risk that a whole system consisting of many interacting agents fails. We describe it as a macroscopic property that emerges from the nonlinear interactions of agents, quite often via cascading processes in which the failure of a few agents is amplified. For this, we have to model (a) the internal dynamics of the agents, which is largely neglected in other approaches, (b) the mechanisms that spread the failure to neighboring agents in the network. As we will show, details matter to distinguish e.g. the debt relations between banks from contagious deseases, or the friendship relations in an online social network.
