Systemic risk describes the likelihood of an entire system breaking down—a situation caused by cascades of failures in the networks that make up the system. Knowledge of such risk can be invaluable. The global economic crisis brought to light the importance of understanding how disturbances spread through financial systems, for example. Epidemics of infectious diseases and the spread of forest fires also illustrate the underlying principals, and importance, of systemic risk.
Crucially, although all systems have unique characteristics, they also share common features. This project will draw together these commonalities to create a general framework for analyzing systemic risk. Once this framework is in place it can be used to assess and reduce risks in a diverse array of applications.
This cross-cutting project aims to develop methods to measure and reduce systemic risk and to provide tools to assess the potential for system collapse, even under uncertainty. This is vital because situations in which specifics about a network’s dynamics are unknown are common in the real world. The researchers will also investigate techniques for guiding the system back to normal after a cascade of failures.
The project will assess risk in ecological systems (under the IIASA Evolution and Ecology program), financial systems (under the Advanced Systems Analysis program), and the global insurance system (under the Risk, Policy and Vulnerability program).
Specifically, three case studies will be examined in depth:
