Inflexibility and Leverage

Firms' inflexibility to adjust their scale persistently explains capital structure variations in a comprehensive sample and randomly-selected sub-samples. Higher inflexibility leads to lower financial leverage, potentially due to higher default risk and lower value of tax shields. Contraction inflexibility determines leverage more than expansion inflexibility. Moreover, inflexibility explains financial leverage on top of operating leverage variability and cash flow variability. Interestingly, the substitution effect between financial and operating leverage is much weaker among flexible firms. In addition, inflexible firms increase leverage more than flexible firms following a positive credit supply shock, which supports our main findings.
