We show that there is a negative relation between leverage and future
growth at the firm level and, for diversified firms, at the business s
egment level. This negative relation between leverage and growth holds
for firms with low Tobin's q ratio, but not for high-q firms or firms
in high-q industries. Therefore, leverage does not reduce growth for
firms known to have good investment opportunities, but is negatively r
elated to growth for firms whose growth opportunities are either not r
ecognized by the capital markets or are not sufficiently valuable to o
vercome the effects of their debt overhang.
