Shareholder activism reshapes corporate governance and stock prices react accordingly.
Corporate governance issues are important for financial managers and shareholders. Shareholders use proposals to influence firm policies. Stock prices react negatively to proposal announcements but positively to settlements. Institutional ownership influences voting outcomes, while managerial ownership and firm size have an inverse relationship with proposal success. Large firms with powerful owner-managers are resistant to shareholder proposals. Rights plans help firms defend against takeovers, especially when combined with high debt levels.
