Whether or not large shareholders actively monitor managers’ behaviours depends not only on their equity stakes but also on the country’s quality of legal rules and enforcement. Jensen and Meckling (1976) and Shleifer and Vishny (1986) posit that controlling shareholders have strong incentives to monitor managers when they have substantial investments in the firm. According to La Porta, Lopez-de-Silanes, Shleifer, and Vishny (2000), in emerging countries where ownership structure of firms is highly concentrated and legal protection of minority shareholders is weak, the controlling shareholders will actively monitor managers to protect private benefits of control. However, the controlling shareholders may also expropriate company resources at the expense of minority shareholders when the controlling shareholders are involved in or connected to the management of the company. Therefore, the net effects of major shareholders in creating or destroying firm value are largely dependent on the contexts of investigation.
