Number 11#
11. Why might one expect managers to act in shareholders' interests? Give some reasons. 12. Many firms have devised defenses that make it more difficult or costly for other firms to take them over. How might such defenses affect the firm's agency problems? Are managers of firms with formidable takeover defenses more or less likely to act in the shareholders interests rather than their own? What would you expect to happen to the share price when management proposes...
