How Big Is Too Big? Critical Shocks for Systemic Failure Cascades

Claudio J. Tessone, Antonios Garas, Beniamino Guerra, Frank Schweitzer
2013 Journal of statistical physics  
For three different threshold distributions P(\theta), we derive analytical results for the size of the cascade, X(t), which is regarded as a measure of systemic risk, and the time when it stops.  ...  If the shock hits only one agent initially and causes it to fail, this can induce a cascade of failures among neighoring agents.  ...  The complex network approach was also used to describe cascading processes in power grids and in Internet services [4, 5] , and was also applied to data storage services [6] .  ...
