This paper presents non-parametric estimates of spectral risk measures applied to long and short positions in 5 prominent equity futures contracts. It also compares these to estimates of two popular alternative measures, the Value-at-Risk (VaR) and Expected Shortfall (ES). The spectral risk...

This paper applies the Extreme-Value (EV) Generalised Pareto distribution to the extreme tails of the return distributions for the S&P500, FT100, DAX, Hang Seng, and Nikkei225 futures contracts. It then uses tail estimators from these contracts to estimate spectral risk measures, which are...

This paper examines the precision of estimators of Quantile-Based Risk Measures (Value at Risk, Expected Shortfall, Spectral Risk Measures). It first addresses the question of how to estimate the precision of these estimators, and proposes a Monte Carlo method that is free of some of the...

One of the most important developments in portfolio risk management in the 1990s was the increased use of Value at Risk (VaR). VaR has enjoyed a spectacular rise, from being largely unknown at the beginning of the 1990s, to prominence among financial institutions and, more recently, also in the...

One of the most significant recent developments in the risk measurement and management area has been the emergence of value at risk (VaR). The VaR of a portfolio is the maximum loss that the portfolio will suffer over a defined time horizon, at a specified level of probability known as the VaR...

This article outlines a subjective approach to estimating value at risk (VaR) and its related confidence intervals based on priors of the profit/loss distribution and its parameters. In the tradition of Bayesian statistics, this pro‐duces probability density functions for VaR that allow for...

This article uses a Value‐at‐Risk approach to derive an estimator of the failure probability of a financial institution. The proposed approach can be applied to any profit/loss distribution, although Extreme Value (EV) theory also tells us that the most appropriate distributions are EV. The...

The pre‐commitment approach to bank capital regulation proposes that banks self‐select capital reserve requirements, facing penalties ex post for incurring losses in excess of reserves, hence providing incentives for high‐ risk banks to choose higher capital requirements. In order to...

Purpose – The purpose of this paper is to review the way in which auditing issues have been raised and addressed during the credit crunch and developing global financial crisis. Design/methodology/approach – Analysis is based on a review of the academic auditing literature, regulatory and...
