This paper analyzes the robustness of standard techniques for risk analysis, with a special emphasis on the Basel III risk measures. We focus on the difference between value-at-risk and expected shortfall, their small sample properties, the scope for manipulating risk measures and how estimation...

This paper evaluates the model risk of models used for forecasting systemic and market risk. Model risk, which is the potential for different models to provide inconsistent outcomes, is shown to be increasing with market uncertainty. During calm periods, the underlying risk forecast models...

We investigate the effects of financial risk cycles on business cycles, using a panel spanning 73 countries since 1900. Agents use a Bayesian learning model to form their beliefs on risk. We construct a proxy of these beliefs and show that perceived low risk encourages risk-taking, augmenting...
