In this paper we examine the problem of partially hedging a given credit risk exposure. We derive hedges which satisfy certain optimality criteria: For a given investment into the hedge they minimize the remaining risk, or vice versa. This is motivated by the fact that it is a core business of...

The aim of this paper is the valuation and hedging of defaultable bonds and options on defaultable bonds. The Heath/Jarrow/Morton-framework is used to model the interest rate risk, and the time of default is determined by the first jump time of a point process. (...)

The authors develop a simple binomial model of liquidity and credit risk in which a bondholder has the option to time the sale of his security, given a distribution of potential buyers, bids and liquidity shocks.

This paper invesitigates the influence of various fundamental variables on a cross-section of credit default swap transaction data.

Starting from the Merton framework for firm defaults, we provide theanalytics and robustness of the relationship between defaultprobabilities and default correlations. We show that loans with higherdefault probabilities will not only have higher variances but also highercorrelations with other...

In this paper, we examine the dynamic behavior of credit spreads on corporate bond portfolios. We propose an econometric model of credit spreads that incorporates portfolio rebalancing, the near unit root property of spreads, the autocorrelation in spread changes, the ARCH conditional...

In this paper, we investigate the pricing of Japanese yen interest rate swaps during the period 1990-96. We obtain measures of the spreads of the swap rates over comparable Japanese Government Bonds (JGBs) for different maturities and analyze the relationship between the swap spreads and credit...

In this study, we examine whether changes in the investment opportunityset stemming from interest rate and credit risks are priced in the US, theUK and the Swiss equity premia by estimating both two-factor and three-factor versions of Merton’s ICAPM. The systematic pricing of credit riskis...

In this paper we analyze the source and magnitude of marketing gains from selling structured debtsecurities at yields that reflect only their credit ratings, or specifically at yields on equivalently ratedcorporate bonds. We distinguish between credit ratings that are based on probabilities of...

The payoff of many credit derivatives depends on the level of credit spreads. Inparticular, credit derivatives with a leverage component are subject to gap risk, a riskassociated with the occurrence of jumps in the underlying credit default swaps. Inthe framework of first passage time models, we...
