ارزیابی سهامداران از بدهی های بلند مدت و کاهش نسبت سرمایه گذاری شرکت ها

The median U.S. non-regulated firm reports a 47% decline in leverage ratio between 1980 and 2010. We investigate whether the cost-benefit tradeoff to shareholders, captured by the valuation impact of an additional dollar of debt on owners' equity, is an explanation for the observed change in leverage. Using Faulkender and Wang (2006) methodology, we find that shareholders view increasing debt to have a negative impact on their wealth, that is, shareholders perceive firms to be over-levered. Further, the net cost of issuing additional debt has increased steadily for three decades beginning in 1980 before declining marginally after 2010. This trend holds for different groups of firms classified on factors known to affect capital structure decisions. Managers respond to the changing cost to shareholders by reducing (increasing) leverage when the cost of debt increases (decreases). The time-series pattern in the marginal cost of debt persists after controlling for firm-specific characteristics. We find that macroeconomic factors, such as federal debt, play a role in explaining the marginal value of debt.
