Dpto. Economía y Empresa

Our evidence suggests that Spanish public firms adjust slowly toward their capital structure target, with the typical firm closing approximately one-fifth of the gap between its current and target debt ratios each year. This finding is in contrast with previous evidence; however, we employ econometric techniques specially designed for highly persistent dependent variables, like market debt ratios. Moreover, our evidence does not seem to indicate that macroeconomic conditions, at least under the conditions experienced by the Spanish economy during our sample period, affect the speed of adjustment. If anything, our results are consistent with faster adjustments during economic states in which the distance between the current and target leverage is the greatest.

We analyze the relevance of adjustment costs in keeping Spanish public firms away from their target leverage. We argue that firm's cash flow outcomes determine the importance of the adjustment costs on capital structure changes. Then, we estimate capital structure adjustment speeds across three different cash flow realizations. We report that during years in which either over-levered or under-levered Spanish public firms make changes in their financing decisions, as a result of their high cash flow realizations, they close significantly more of the gap between current and target capital structure than those firms with intermediate and low cash flow observations. Moreover, independently of the cash flow level, we find that leverage adjusts more quickly for over-levered than for under-levered firms.
