A Growth Type Explanation for Capital Structure Persistence

Abstract:     
Recent research has revealed a persistent cross-sectional pattern in leverage ratios but found it difficult to explain. We show that growth-type (largely revealed early on) can parsimoniously explain the persistent dispersion in leverage. Using a two-way independent sort on firm initial market-to-book ratio and asset tangibility in early IPO years, we classify firms into three growth-types (low, mixed and high). We find that on average, low-growth firms have significantly higher leverage, high-growth firms have significantly lower leverage, and mixed-growth firms are in the middle. Growth-type is persistent and characterizes firms in profound ways. For example, throughout the years, low-growth firms focus on more tangible investments while high-growth firms tilt overwhelmingly towards R&D investments. Interestingly, while heavy issues of new equity by high-growth firms push their low leverage ratios even lower, it is the huge decreases in retained earnings - due to the expensing or amortizing of relentless R&D or intangible investments that pay off slowly - instead of issues of new debt that pull the leverage ratios back and help sustain leverage persistence. As the growth-type story suggests, we find that growth-type predetermines firms' persistent pecking order preference in external finance. We are able to show that it is growth-type rather than market timing that best explains leverage persistence.
