A model of dynamic capital structure is proposed. Even though the optimal strategy is implemented over an arbitrarily large number of restructuring-periods, a scaling feature inherent in the framework permits simple closed-form expressions to be obtained for equity and debt prices. When a firm...

This article develops a model in which optimal capital structure and debt maturity are jointly determined in a stochastic interest rate environment. The model yields leverage ratios that are consistent in spirit with empirical observations. The optimal maturity and credit spread of an optimally...

This paper provides a closed-form density approximation when the underlying state variable is a one-dimensional diffusion. Building on Aït-Sahalia (2002), we show that our refinement is applicable under a wide class of drift and diffusion functions. In addition, it facilitates the maximum...

After September 11, 2001, there was a great deal of speculation that the terrorists or their associates had traded in the option market on advanced knowledge of the impending attacks. This paper generates systematic information about option market activity that can be used to assess the option...
