By using short-term direct finance firms of the highest credit quality exposethemselves to rollover risk in the public debt markets. Firms insure themselvesagainst this risk by securing backup lines of credit from banks that they mayuse should market liquidity dry up. In a first step, this paper...

In der vorliegenden Studie wird das Pricing aktiengebundener Lebensversicherungen mit Mindestgarantiezins in einem Gleichgewichtsmodell untersucht. Dazu werden Modelle zur Berechnung der Default-Option und der Ausfallwahrscheinlichkeiten eingeführt. Die Modelle binden Angebot- und...

Loss Given Default (LGD) is a major element for pricing credits and bonds. As there has beena substantial amount of research during the last years, this paper aims to give an overview.Initially, defaults and recovery definitions for credits and the differences to bonds are discussed.A survey of...

Financial institutions are faced with the challenge to forecast future credit portfolio losses.It is common practice to focus on portfolio models consisting of a limited set of parameters,such as the probability of default, asset correlation, loss given default or exposure at default.A simple...

The validation of probability calibration is an inherently difficult task. We develop a testing procedure for credit-scoring models. The models comprise two components to check whether the ex-ante probabilities support the ex-post frequencies. The first component tests the level of the...
