Local Volatility Enhanced by a Jump to Default
نویسندگان
چکیده
A local volatility model is enhanced by the possibility of a single jump to default. The jump has a hazard rate that is the product of the stock price raised to a prespecified negative power and a deterministic function of time. The empirical work uses a power of −1.5. It is shown how one may simultaneously recover from the prices of credit default swap contracts and equity option prices both the deterministic component of the hazard rate function and revised local volatility. The procedure is implemented on prices of credit default swaps and equity options for General Motors and the Ford Motor Company over the period October 2004 to September 2007.

Credit Spreads, Optimal Capital Structure, and Implied Volatility with Endogenous Default and Jump Risk
We propose a two-sided jump model for credit risk by extending the Leland-Toft endogenous default model based on the geometric Brownian motion. The model shows that jump risk and endogenous default can have significant impacts on credit spreads, optimal capital structure, and implied volatility of equity options: (1) The jump and endogenous default can produce a variety of non-zero credit sprea...
متن کاملModeling Credit Risk in the Jump Threshold Framework
Abstract The jump threshold framework for credit risk modeling developed by Garreau and Kercheval (2016) enjoys the advantages of both structural and reduced form models. In their paper, the focus is on multi-dimensional default dependence, under the assumptions that stock prices follow an exponential Lévy process (i.i.d. log returns) and that interest rates and stock volatility are constant. E...
متن کاملInterpreting Recent Changes in the Credit Spreads of Japanese Banks
This paper examines the recent period of relatively low credit spreads in Japan, with particular emphasis on the market’s assessments of the credit risks of large Japanese banks implicit in the prices of credit derivatives. We extract the market-price implied likelihood of a credit event in the future, and explore the nature of the default risk premiums underlying recent changes in bank bond an...
متن کاملPricing Model of Credit Default Swap Based on Jump-Diffusion Process and Volatility with Markov Regime Shift
By introducing the Jump-Diffusion Process and Markov Regime Shift, the paper explores Monte Carlo simulation to examine the pricing problem of single name Credit Default Swaps (CDS), which the price of CDS is affected by both unpredictable idiosyncratic risk and system risk caused by the macroeconomic change. The study shows that the price of CDS increases as the intensity and the amplitude of ...
متن کاملTime Changed Markov Processes in Unified Credit - Equity Modeling ∗
This paper develops a novel class of hybrid credit-equity models with state-dependent jumps, local-stochastic volatility and default intensity based on time changes of Markov processes with killing. We model the defaultable stock price process as a time changed Markov diffusion process with state-dependent local volatility and killing rate (default intensity). When the time change is a Lévy sub...
