The Effect of Business Risk on Corporate Capital Structure: Theory and Evidence
在企业和个人税收背景下，发现最优债务水平与商业风险呈U型关系，并通过实证检验支持这一预测。
ABSTRACT Under corporate and personal taxation, we demonstrate that the relation between optimal debt level and business risk is roughly U‐shaped. This result follows from the fact that the tax liability is an option portfolio that is long in the corporate tax option and short in the personal tax option. Therefore, the net effect of a change in business risk on the optimal debt level depends upon the relative magnitudes of the resultant marginal changes in the values of these two options. Results of empirical tests offer support for the predicted U‐shaped relationship.
