Credit Derivatives and Risk Aversion
نویسندگان
چکیده
We discuss the valuation of credit derivatives in extreme regimes such as when the time-tomaturity is short, or when payoff is contingent upon a large number of defaults, as with senior tranches of collateralized debt obligations. In these cases, risk aversion may play an important role, especially when there is little liquidity, and utility indifference valuation may apply. Specifically, we analyze how short-term yield spreads from defaultable bonds in a structural model may be raised due to investor risk aversion.

Utility Valuation of Credit Derivatives: Single and Two-Name Cases
We study the effect of risk aversion on the valuation of credit derivatives. Using the technology of utility-indifference valuation in intensity-based models of default risk, we analyze resulting yield spreads for single-name defaultable bonds, and a simple representative two-name credit derivative. The impact of risk averse valuation on prices and yield spreads is expressed in terms of effecti...
متن کاملUtility Valuation of Multiname Credit Derivatives and Application to CDOs
We study the impact of risk-aversion on the valuation of credit derivatives. Using the technology of utility-indifference pricing in intensity-based models of default risk, we analyze resulting yield spreads in multiname credit derivatives, particularly CDOs. We study first the idealized problem with constant intensities where solutions are essentially explicit. We also give the large portfolio...

The paper gives an overview of mathematical models and methods used in financial risk management; the main area of application is credit risk. A brief introduction explains the mathematical issues arising in the risk management of a portfolio of loans. The paper continues with a formal overview of credit risk management models and discusses axiomatic approaches to risk measurement. We close wit...
متن کاملTime - inhomogeneous Lévy processes in interest rate and credit risk models
In this thesis, we present interest rate models and a credit risk model, all driven by time-inhomogeneous Lévy processes, i.e. stochastic processes whose increments are independent but in general not stationary. In the interest rate part, we discuss a Heath–Jarrow–Morton forward rate model (the Lévy term structure model), a model for forward bond prices (the Lévy forward price model) and a Libo...
متن کاملCredit Risk and the Role of Capital Adequacy Regulation
Using the industrial organization approach to the microeconomics of banking we model a large (Monti-Klein) bank which is risk neutral and faces credit uncertainty in its loan business. The impact of capital adequacy regulation and the effect of changes in risk on deposit and loan rates are analyzed. We then show that capital adequacy regulation induces the bank to behave as if it were risk aver...
