We conduct a systematic comparison of confidence intervals around estimated probabilities of default (PD), using several analytical approaches from large-sample theory and bootstrapped small-sample confidence intervals. We do so for two different PD estimation methods

In this paper, we analyze the impact of a decline in property prices that leads to stressed recovery rates for collateral on the loss given default (LGD) parameter in portfolios of mortgage loans. We prove that the average LGD's stress sensitivity depends on the portfolio's loan-to-value (LTV-)...

This paper examines the impact of regulatory reform on TFP growth and its sources and on the relationship between ownership and cost efficiency for Indian banks in 1992-2004. The methodology consists of the joint use of parametric and non-parametric techniques to estimate efficiency frontiers....

Value at risk (VaR) has become a standard measure of portfolio risk over the last decade. It even became one of the corner stones in the Basel II accord about banks' equity requirements. Nevertheless, the practical application of the VaR concept suffers from two problems: how to estimate VaR and...

A flexible framework for the analysis of tail events is proposed. The framework contains tail moment measures that allow for Expected Shortfall (ES) estimation. Connecting the implied tail thickness of a family of distributions with the quantile and expectile estimation, a platform for risk...

The goal of integrated risk management in a financial institution is to measure and manage risk and capital across a range of diverse business activities. This requires an approach for aggregating risk types (market, credit, and operational) whose distributional shapes vary considerably. In this...

The derivation of the bi-variate Payoff Distribution model by Kat and Palaro (2005) represents an interesting contribution to the performance evaluation and asset pricing literature. Nonetheless, their approach for evaluating the function is significantly flawed. Recently, Papageorgiou et al....

In this paper, we present a new alternative performance measure (APM) which evaluates not only for the marginal distribution of a given fund but also its' dependence (correlation) with a reference portfolio. This performance measure is of particular value in assessing hedge fund return as the...

This paper conducts an empirical analysis with regard to those methodologies proposed by the Basle Committee for the estimation of the operational capital charge. More specifically, we compare an advanced measurement approach, as the Loss Distribution Approach (LDA), versus the so called...
