The literature on corporate credit risk modeling for privately-held firms is scarce. Although firms with unlisted equity or debt represent a significant fraction of the corporate sector worldwide, research in this area has been hampered by the unavailability of public data. This study is an...

A family of credit risk models is proposed to capture three salient features of Latin American (LA) Sovereign Bond Markets: individual Long Range Dependence in volatility---Long Memory (LM)---, high fractional comovement and time varying risk premia. Evidence in favor of LM is uncovered and the...

Recently there has been some interest in the credit risk literature in models which involve stopping times related to excursions. The classical Black-Scholes-Merton-Cox approach postulates that default may occur, either at or before maturity, when the firm's value process falls below a critical...

In this paper, we develop a generalized affine model to characterize correlated credit risk of multi-firms. When valuing credit derivatives, this new approach allows to incorporate correlative market and credit risk, interdependent default risk structure and counterparty risk into consideration....

In this paper we have combined fundamental analysis and contingent claim analysis into a hybrid model of credit risk measurement. We have extended the standard Merton approach to estimate a new risk neutral distance to default metric, assuming a more complex capital structure, adjusting for...

We extend the credit risk valuation framework introduced by Gatfaoui (2003) to stochastic volatility models. We state a general setting for valuing risky debt in the light of systematic risk and idiosyncratic risk, which are known to affect each risky asset in the financial market. The option...

Farmer Mac is the GSE charged with creating a secondary market in loans backed by agricultural real estate. The Farm Credit Administration (FCA) has estimated a credit risk model for agricultural mortgages. This model is a key determinant of Farmer Mac’s risk based capital (RBC) requirement....

This paper examines the role and determinants of collateral in emerging markets compared to mature ones. Analyzing a data set of 560 credit files of Thai commercial banks, we find that both the incidence and degree of collateralization are higher there than in developed markets. Thai banks use...

The purpose of this paper is to see whether and how G-10 banks have complied with the 1988 Basel Accord. The interest of this study lies in the fact that the standardized approach to credit risk in the New Basel Accord is conceptually similar to the 1988 agreement. However, very little is known...

In this paper, by applying the potential approach to characterizing default risk, a class of simple affine and quadratic models is presented to provide a unifying framework of valuing both risk-free and defaultable bonds. It has been shown that the established models can accommodate the existing...
