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...

We develop a model in which a financial intermediary's investment in risky assets - risk taking - is excessive due to limited liability and deposit insurance, and characterize the policy tools that implement efficient risk taking. In the calibrated model, coordinating interest rate policy with...
