We propose a fast algorithm for computing the expected tranche loss in the Gaussian factor model with arbitrary accuracy using Hermite expansions. No assumptions about homogeneity of the portfolio are made. The algorithm is a generalization of the algorithm proposed in \cite{PO}. The advantage...

We provide a fast algorithm to calculate the m-dimensional distance histogram on which Brock, Dechert, and Sheinkman's (1987) BDS-type statistics are based. The algorithm generalizes a fast algorithm due to LeBaron by calculating the histogram for any finite set of distances simultaneously, and...

Исследованы зависимости между ковариационными матрицами, вычисляемыми в процессе многомерной рекурсии Левинсона. Показано, что учет выявленных взаимосвязей...

This paper examines the marginal distributions of stocks and bonds, and a copula between the movement of stock prices and interest rates. Because some widely used aggregation methods such as variance-covariance tend to underestimate the risk of an aggregated portfolio, a copula is utilized for...

A framework is identified for modeling credit risk in agriculture. A CreditRisk+ type model is deemed most suitable for agricultural lending. The CreditRisk+ model is modified to overcome its drawbacks by incorporating recent research that accounts for sector correlations and uses a more stable...

The concept of reputation was introduced to management literature from sociological literature on impression management. Fombrun developed an understanding of reputation in business by introducing several aspects of corporate reputation. However, attempts at making it all-inclusive resulted in...

This study provides responses to the question of the effectiveness of Loan-To-Value (LTV) and Debt Service-To-Income (DSTI) caps to contribute to financial stability. Using a lender’s risk management perspective, the paper provides a new methodology extending the standard asymptotic single...
