In this paper we focus on the analysis of the effect of prediction and estimation risk on the loss distribution, risk measures and economic capital. When variables for the determination of probability of default and loss distribution have to be predicted because they are not available at the...

Estimating quantile sensitivities is important in many optimization applications, from hedging in financial engineering to service-level constraints in inventory control to more general chance constraints in stochastic programming. Recently, Hong (Hong, L. J. 2009. Estimating quantile...

Microfinance in Mexico has developed at an accelerated pace and the efforts in credit risk management in this sector are scarce. The goal of this work is the construction of a Transition Probability Matrix in the rating of microcredits which can be used in the estimation of Value at Risk (VaR),...

Modern risk management systems were developed in the early 1990s to provide centralized risk measures at the top level of financial institutions. These are based on a century of theoretical developments in risk measures. In particular, value at risk (VAR) has become widely used as a statistical...

The objective of this paper is to study the effect of importance sampling (IS) techniques on stochastic credit portfolio optimization methods. I introduce a framework that leads to a reduction of volatility of resulting optimal portfolio asset weights. Performance of the method is documented in...

Im vorliegenden Beitrag wird untersucht, wie die Assetkorrelation zwischen zwei Sektoren auf einfache Weise berechnet werden kann und wie sich unterschiedliche Korrelationsannahmen auf die Form und Risikomaße von Verlustverteilungen auswirken. Dazu werden Ausfallzeitreihen von zwei...

Die Messung und Bewertung von Kreditrisiken stellt sich aktuell als ein sehr bedeutsames (Stichworte : Basel II, Solvency II, Kreditderivate) Gebiet dar. Allerdings hat sich hierbei keine einheitliche Vorgehensweise herausgebildet, sondern es existieren eine Vielzahl unterschiedlicher...

The paper analyzes, on the base of a presented sampling, the trends of population crediting by the banks in the Siberian Federal District in the periods of the pre-crisis, crisis and post-crisis restoration. We can state that in the crisis a sex structure of borrowers (physical persons) has...
