Importance sampling for portfolio credit risk
WitrynaImportance Sampling for Estimating Risk Measures in Portfolio Credit Risk Models Zhao Li October 2009 Abstract This paper is the report of a Master’s Degree project carried out at Royal Institute of Technology and in this paper we mainly apply the estimators and methods derived by P. Glasserman and J. Li (2003, 2005) of importance Witrynaportfolio credit risk, an important step toward active risk management is to measure risk contributions of individual obligors to the overall risk of the portfolio. In practice, value-at-risk is often used as a risk measure for credit portfolios, and it can be decomposed into a sum of the risk contributions of individual obligors.
