Treating natural and human-made systems as networks allows the interdependence of their parts to be addressed in a tractable way; considering dynamic networks also allows systemic risks to be addressed and resilience investigated.
In 2014 ASA studied the branch of systems ecology known as systems ecology where species or functional groups interact through predation; examined “femtorisks” or risks that are perceived as extremely unlikely or small, but because of interconnections or changes in systems, can lead to major collapses or crises; it also made theoretical advances on so-called generalized mini-max solutions to non-zero-sum games of two large groups of agents interacting randomly with each other.
Advanced System Analysis (ASA) Program researchers develop methods and case-studies analyzing ecological, economic, energy, financial and other networked empirical systems. These methods often originate in the natural science disciplines (e.g., physics, ecology) and then transfer to social sciences disciplines (e.g., economics). More
Advanced Systems Analysis (ASA) Program researchers develop dynamic network models of ecological, economic, and social systems. There is a particular focus on the issue of financial systemic risk and cascading failures in the inter-bank lending network. More
Advanced Systems Analysis (ASA) Program researchers are advancing game theory approaches and applying them to the study of stylized models of social interactions. More
