paper analyzes the impact of model complexity on the valuation of project financed investments along two dimensions: The NPV distribution and the expected default probability of the project. Model complexity is separated in forecast and simulation complexity. Thereby, we aim to identify elements...

Der Beitrag beginnt mit einer Darlegung der Entstehungsgründe für die Nutzung von Finanzkontrakten als Instrumente des versicherungswirtschaftlichen Risikomanagements ...

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 authors determine the time horizon on the risk of stock investments.

In the ideal Black-Scholes world, financial time series are assumed 1) stationary (time homogeneous) and 2) having conditionally normal distribution given the past. These two assumptions have been widely-used in many methods such as the RiskMetrics, one risk management method considered as...

Over recent years, study on risk management has been prompted by the Basel committee for regular banking supervisory. There are however limitations of some widely-used risk management methods that either calculate risk measures under the Gaussian distributional assumption or involve numerical...

Risk management technology applied to high dimensional portfolios needs simple and fast methods for calculation of Value-at-Risk (VaR). The multivariate normal framework provides a simple off-the-shelf methodology but lacks the heavy tailed distributional properties that are observed in data. A...
