Since Berle and Means’ (1932) study, the agency problems caused by the separation of ownership and control, and the effects of different types of shareholders on firm value, have received considerable attention in finance literature. According to Jensen and Meckling (1976), the agency problems normally stem from the divergence of interests of managers who run the firms and those of outside investors who supply the capital. Rather than maximise shareholders’ wealth, a manager might expropriate corporate resources for his own benefits such as spending company’s cash for a lavish office, setting excessive salaries, and undertaking negative Net Present Value projects in order to build empires. These counterproductive activities are definitely detrimental to shareholders’ wealth. One method to reduce agency problems is for large shareholders to exert their powers to control and monitor managers. Hence, large shareholders can play crucial roles in providing effective corporate governance mechanisms, thereby increasing corporate value.
