This paper develops a model of dynamic capital structure choice in the presence of recapitalization costs. The theory provides the optimal dynamic recapitalization policy as a function of firm-specific characteristics. We find that even small recapitalization costs lead to wide swings in a firm's debt ratio over time. Rather than static leverage measures, we use the observed debt ratio range of a firm as an empirical measure of capital structure relevance. The results of empirical tests relating firms' debt ratio ranges to firm-specific features strongly support the theoretical model of relevant capital structure choice in a dynamic setting.

This paper develops a model of dynamic capital structure choice in the presence of recapitalization costs. The theory provides the optimal dynamic recapitalization policy as a function of firm‐specific characteristics. We find that even small recapitalization costs lead to wide swings in a firm's debt ratio over time. Rather than static leverage measures, we use the observed debt ratio range of a firm as an empirical measure of capital structure relevance. The results of empirical tests relating firms' debt ratio ranges to firm‐specific features strongly support the theoretical model of relevant capital structure choice in a dynamic setting.

In a recent article, MacMinn [5] argues that the presence of forward markets eliminates the incentives of the firm's manager to choose production levels that maximize firm value. In this comment, we show that his results do not depend on the presence of forward markets. The critical assumptions are that the manager is endowed with money rather than stock in the firm and that there is no competitive labor market for managers. In addition, his results require time‐inconsistent behavior on the part of the firm's manager.
