In our paper, A Theory of Debt Maturity: The Long and Short of Debt Overhang, forthcoming in the Journal of Finance, we study the effects of the debt maturity on current and future real investment decisions of an owner of equity (or a manager who is compensated by equity). Our analysis is based on debt overhang first analyzed by Myers (1977), who points out that outstanding debt may distort the firm’s investment incentives downward. A reduced incentive to undertake profitable investments when decision makers seek to maximize equity value is referred to as a problem of “debt overhang,” because part of the return from a current new investment goes to make existing debt more valuable.
Myers (1977) suggests a possible solution of short-term debt to the debt overhang problem. In part, this extends the idea that if all debt matures before the investment opportunity, then the firm without debt in place can make the investment decision as if an all-equity firm. Hence, following this logic, debt that matures soon—although after relevant investment decisions, as opposed to before—should have reduced overhang.
