Historical VaR, CVaR and ES (Expected Shortfall) to LIQUIDATION Software is a model characterized by its straightforwardness, allowing regulators measure risk using a standard database of primitive factors and portfolio positions only, leaving little error margin in comparing market risk for...

In measuring its Operational Risk VaR, a bank needs to pay attention when including external data in its internal loss collection. In principle, these data should be scaled consistently to the specific nature of the bank's risk, but this is not done by the majority of institutions with advanced...

We put climate risks in the perspective of model risk using a model in the wide sense. Climate risks are systemic risks and may be clustered according to so-called volatilities, uncertainties, complexities and ambiguities (VUCA) criteria. The dominating VUCA component of climate risk is...

limate variability and extremes, socio-economic conditions, crisis and market shocks are among the main factors determining risk in the agricultural sector. Drought, heat stress, flood, market volatility among the others, have caused heavy losses in the recent past and both the occurrence and...

At a 2019 retirement security conference in Brazil, one of the authors proposed that Brazil introduce a low-cost, low-risk, simple and liquid bond innovation: “SeLFIES”— Standard of Living indexed, Forward-starting, Income-only Securities. SeLFIES would serve as the relative safe asset for...

In modern frameworks for financial regulation such as Basel III, IV as well as Solvency II, financial institutions are regulated to maintain a certain level of capital to prepare for potential future losses. In this paper, we take the perspective of a regulator who designs regulatory capital...

Der Beitrag enthält eine anreiztheoretische Analyse der Versicherungssysteme, die zur Entschädigung von Kosten und Verlusten aus Tierseuchenausbrüchen in den EUMitgliedsländern eingerichtet sind. Es wird gezeigt, dass Kompensationszahlungen zur Erzielung effizienter Schadenverhütungsanreize...

This paper considers the financial optimization problem of a firm with several sub-businesses striving for its optimal RORAC. An insightful example shows that the implementation of classical gradient capital allocation can be suboptimal if division managers are allowed to venture into all...
