A framework for an optimized capital structure for state-owned natural monopolies
Nxumalo, Khulekani Sydwell
This study empirically examines whether the capital structure for natural monopolies (parastatals) dynamically responds to macroeconomic conditions. It further examines whether the balance sheet channel theory holds for this industry sample. The study adopts a double sampling approach from the population of water boards in South Africa (SA), which raise their capital in open financial markets. A quantitative research approach is adopted with a descriptive design to achieve relevant deductions. Panel techniques are used in the descriptive design for the regressions. The study finds that leverage partly dynamically responds to macroeconomic conditions. Furthermore, the evidence shows that inflation is an exception that has no significant relationship with leverage. The balance sheet channel theory is found to hold for water boards that access capital in open financial markets. Specifically, empirical evidence shows that changes in the interest rate have a delayed impact on the companies’ characteristics, including capital structure. Overall, our evidence suggests that water boards in SA need to consider the benefits of linking financial policies to the business cycle and that their policies should consider the delayed effect of interest rate changes.
