Double Exponential Jump Diffusion Process: A Structural Model of Endogenous Default Barrier with Roll-over Debt Structure
نویسندگان
چکیده
In this paper, we extend the framework of Leland (1994b) who proposed a structural model of roll-over debt structure in a Black-Scholes framework to the case of a double exponential jump diffusion process. We consider a trade-off model with firm’s parameters as firm risk, riskfree interest rate, payout rate as well as tax benefit of coupon payments, default costs, violation of the absolute priority rule and tax rebate. We obtain the equity, debt, firm and credit spreads values in closed form formulae. We analyze these values as functions of coupon, leverage and maturity.

Closed formulas for the price and sensitivities of European options under a double exponential jump diffusion model
We derive closed formulas for the prices of European options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by S. Kou in 2002. This author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...
متن کاملEfficient Pricing Routines of Credit Default Swaps in a Structural Default Model with Jumps
In this paper, we present two efficient algorithms for pricing credit default swaps based on a structural default model. In our model, the value of the firm is assumed to be the exponential of a jump-diffusion process. Our first algorithm to price a credit default swap within this framework is an efficient and unbiased Monte Carlo simulation. An excellent performance is obtained by first simula...
متن کاملRethinking dynamic capital structure models with roll-over debt∗
Dynamic capital structure models with roll-over debt rely on widely accepted arguments that have never been formalized. This paper clarifies the literature and provides a rigorous formulation of the equity holders’ decision problem within a game theory framework. We spell out the linkage between default policies in a rational expectations equilibrium and optimal stopping theory. We prove that t...
متن کاملOn the modeling of Debt Maturity and Endogenous Default: A caveat∗
We focus on structural models in corporate finance with roll-over debt structures in the vein of Leland (1994) and Leland and Toft (1996). We show that these models incorrectly assume that the optimal default is defined by the first time such that the firm’s assets reaches a sufficiently low positive threshold that must be optimally determined. We characterize the optimal default policy and exp...
متن کاملCredit 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...
