We examine the relation between the cost of debt financing and a governance index that contains various antitakeover and shareholder protection provisions. Using firm-level data from the Investors Research Responsibility Center for the period 1990–2000, we find that antitakeover governance provisions lower the cost of debt financing. Segmenting the data into firms with the strongest management rights (strongest antitakeover provisions) and firms with the strongest shareholder rights (weakest antitakeover provisions), we find that strong antitakeover provisions are associated with a lower cost of debt financing while weak antitakeover provisions are associated with a higher cost of debt financing, with a difference of about 34 basis points between the two groups. Overall, the results suggest that antitakeover governance provisions, although not beneficial to stockholders, are viewed favorably in the bond market.

This paper examines optimal capital structure choice using a dynamic capital structure model that is calibrated to reflect actual firm characteristics. The model uses contingent claim methods to value interest tax shields, allows for reorganization in bankruptcy, and maintains a long-run target debt to total capital ratio by refinancing maturing debt. Using this model, we calculate optimal capital structures in a realistic representation of the traditional trade-off model. In contrast to previous research, the calculated optimal capital structures do not imply that firms tend to use too little leverage in practice. We also estimate the costs borne by a firm whose capital structure deviates from its optimal target debt to total capital ratio. The costs of moderate deviations are relatively small, suggesting that a policy of adjusting leverage infrequently is likely to be reasonable for many firms.
