We study how corporate governance affects firm value through the decision of whether to fire or retain the CEO. We present a model in which weak governance - which prevents shareholders from controlling the board - protects inferior CEOs from dismissal, while at the same time insulates the board from pressures by biased or uninformed shareholders. Whether stronger governance improves retain/replace decisions depends on which of these effects dominates. We use our theoretical framework to assess the effect of governance on the quality of firing and hiring decisions using data on the CEO dismissals of large U.S. corporations during 1994-2007. Our findings are most consistent with a beneficent effect of weak governance on CEO dismissal decisions, suggesting that insulation from shareholder pressure may allow for better long-term decision-making.



From Adam Smith (1776) and Berle and Means (1932) to Hermalin and Weisbach (1998), economists have expressed concern about entrenched CEOs’ ability to pursue personal gain at the expense of shareholders. The prevailing belief is that firms risk value destruction by self-serving CEOs, if they are left unchecked by weak boards or weak shareholders. At the same time, many companies have actively chosen to weaken shareholders’ powers with the explicit aim of ensuring that long-term profits are maximized. Most recently, Facebook, LinkedIn, and Groupon completed initial public offerings (IPOs) with dual class share structures—with * We thank Ren´e Adams, Thomas Chemmanur, Bruce Greenwald, Steve Kaplan, Bengt Holmstrom, Vinnay Nair, e

super-voting shares retained by insiders. In Google’s case, the company introduced a new class of nonvoting shares, saying, “outside pressures [from stockholders] too often tempt companies to sacrifice long term opportunities to meet quarterly market expectations.”1 Google’s concern about too much shareholders influence seems at odds with the traditional notion that entrenchment—the insulation of CEOs from shareholders—is bad for firms’ performance. In this paper, we incorporate both of these views into a theory of entrenchment that distinguishes between the ability of CEOs to control the board (the “CEO Protection” view) versus the board’s ability to ignore shareholders (the “Board Protection” view). The literature on entrenchment largely ignores this distinction, assuming that board dependence on the CEO and insulation from shareholders have the same effect—protecting inferior CEOs. In our model, the CEO Protection and Board Protection views have differing effects on the firm. Specifically, we examine the quality of the board’s decision to retain or fire CEOs. We focus on this decision because it one of the board’s primary functions, one that is made solely by the board, and one that lies at the heart of the debate on the costs of board entrenchment. We formally present and empirically examine a model that establishes distinct predictions for the CEO Protection and Board Protection views of entrenchment, and find evidence that limiting shareholder power over boards—that...
