Abstract

This paper aims to examine the effect of ownership structure on the cost of equity capital in the Tunisian context. Using panel data, the study provides evidence for a negative relationship between ownership concentration and cost of equity capital. However, most ownership composition variables validate the entrenchment effect. Results show an inverted U-shaped relationship between institutional ownership, foreign ownership and cost of equity capital. However, a U-shaped relationship is found between state ownership and the dependent variable. To alleviate endogeneity concerns and establish that the results are robust, the authors re-estimated the regressions using a dynamic approach. It supports the entrenchment effect of ownership concentration. A U-shaped relationship between this variable and the cost of equity capital is confirmed. However, a concave relationship is found when considering ownership composition variables. As for family ownership, the results from static and dynamic approaches are convergent and in favour of entrenchment effects.
