This paper makes use of two types of extreme value distributions, namely: the generalised extreme value distribution often referred to as the block of maxima method (BMM), and the peak-over-threshold method (POT) of the extreme value distributions, to model the financial tail risks associated...

There is a vast literature on the selection of an appropriate index of income inequality and on what desirable properties such a measure (or index) should contain. The Gini index is, of course, the most popular. There is a concurrent literature on the use of hypothetical statistical...

Following Bali and Weinbaum (2005) and Maillet et al. (2010), we present several estimates of volatilities computed with high- and low frequency data and complement their results using additional measures of risk and several alternative methods for Tail-index estimation. The aim here is to...

This paper is the result of the author's many years of multidisciplinary research in the areas of quality management and operational risk management. The main focus of the research is aimed at strengthening the model of the "three lines of defence" in terms of more efficient management of...

Operational risk is defined as the potential losses resulting from events caused by inadequate or failed processes, people, equipment, and systems or from external events. One of the most important challenges for the management of the company is to improve its results through its operational...

This paper proposes a methodology to analyze the implications of the Advanced Measurement Approach (AMA) for the assessment of operational risk put forward by the Basel II Accord. The methodology relies on an integrated procedure for the construction of the distribution of aggregate losses,...

Operationelle Risiken (OpRisiken) haben in den letzten Dekaden sehr viel an Aufmerksamkeit in Finanzinstituten erregt und dadurch zunehmend an Bedeutung gewonnen. Zahlreiche milliardenschwere Verluste wurden aufgrund von Nichtbeachtung bzw. Fehleinschätzung solcher Risiken in der...
