The Leland-Toft optimal capital structure model under Poisson observations

Abstract

We revisit the optimal capital structure model with endogenous bankruptcy first studied by Leland Leland94 and Leland and Toft Leland96. Differently from the standard case, where shareholders observe continuously the asset value and bankruptcy is executed instantaneously without delay, we assume that the information of the asset value is updated only at intervals, modeled by the jump times of an independent Poisson process. Under the spectrally negative L\'evy model, we obtain the optimal bankruptcy strategy and the corresponding capital structure. A series of numerical studies are given to analyze the sensitivity of observation frequency on the optimal solutions, the optimal leverage and the credit spreads.
