Purpose
The purpose of this paper is to explore the impact of leverage on firms’ discretionary investment in Africa.
Design/methodology/approach
The authors employ a dynamic panel data model estimated with generalised method of moments (GMM) estimation techniques on the panel data of listed African non-financial firms. A dynamic model and the generalised methods of moments estimations are handy in controlling for unobserved heterogeneity, endogeneity, autocorrelation, heteroscedasticity, etc.
Findings
In spite of different settings, markets, leverage levels and methodologies, the authors found evidence that leverage constrains investment in African firms. The negative impact is more pronounced in firms with low-growth opportunities than in firms with high-growth opportunities. The results are inclined to the theory that leverage plays a disciplinary role to avoid overinvestment.
Research limitations/implications
African firms’ investment policy does not solely depend on the neoclassical fundamentals determinants of profitability, net worth and cash flows. Financing strategy also has a considerable bearing on the investment policy. The results provide evidence that leverage is a negative externality to the firm’s discretional investment policy for both lowly levered and highly leveraged firms. African firms’ should consider maintaining their low debt levels and rely more on internally generated funds so as not to suppress any available cash flows to interest payments and loan covenants from debt holders.
Originality/value
The study contributes to the literature on investment and financial leverage by the authors providing evidence from Africa, a developing continent, that has not been explored. It shows how conservative leverage levels of African firms, which have been reported to be rising, are impacting on investments. Pertaining to empirical methodology, the authors employ a dynamic panel data model, the GMM estimation technique, which is robust in controlling endogeneity, and a possible bi-directional causality between leverage and investment which have not been used in literature. The study also enables a comparison of the effect of high leverage and low leverage on firm’s discretional investment.
