"Stress tests are the most innovative regulatory tool to prevent and fight financial crises. Their use has fundamentally changed the mathematical modeling of financial systems, financial risk management in the public and private sector, and the policies designed to prevent and mitigate financial...

We review heterogeneous agent-based models of financial stability and their application in stress tests. In contrast to the mainstream approach, which relies heavily on the rational expectations assumption and focuses on situations where it is possible to compute an equilibrium, this approach...

Currently financial stress test simulations that take into account multiple interacting contagion mechanisms are conditional on a specific, subjectively imposed stress-scenario. Eigenvalue-based approaches, in contrast, provide a scenario-independent measure of systemic stability, but only...

We propose a structural framework for the development of system-wide financial stress tests with multiple interacting contagion, amplification channels and heterogeneous financial institutions. This framework conceptualises financial systems through the lens of five building blocks: financial...

What kind of models do we need to guide us through the next crisis? If past crises are any indication, we need to explore new approaches. During the Great Financial Crisis, the models that existed at the time were of little value because they focused on firm-level interactions and did not...
