This paper studies communication and intervention as mechanisms of governance. I develop a model in which a privately informed principal can overrule the decisions of the agent (intervention) if the agent disobeys the principal's instructions (communication). The main result shows that intervention can be counterproductive, as it undermines the principal's ability to resolve the conflict with the agent through communication. I show that the possibility of intervention creates additional tension between the principal and the agent by providing the agent with opportunities to challenge the principal to "back her words with actions". This result provides a novel argument as to why a commitment not to intervene can be beneficial to the principal, echoing the common wisdom that the capacity to make unilateral decisions can discourage effective deliberation, cooperation and compliance. The analysis sheds new light on the effectiveness of different governance arrangements and provides novel predictions about expected patterns of intervention.
This paper studies the corporate governance and asset pricing implications of investors owning blocks in multiple firms. Common wisdom is that multi-firm ownership weakens governance because the blockholder is spread too thinly. We show that this need not be the case. In a single-firm benchmark, the blockholder governs through exit, selling her stake if the firm underperforms. With multiple firms, the blockholder may sell even a value-maximizing firm, to disguise her exit from another underperforming firm as being motivated by a portfolio-wide liquidity shock. This reduces the manager's effort incentives and weakens governance. On the other hand, governance can be stronger, because selling one firm and not the other is a powerful signal of underperformance. Common ownership leads to firms' stock prices being correlated, even if their fundamentals are uncorrelated. We derive empirical predictions for the direction of correlation and for whether governance is stronger or weaker with multiple firms.
This paper examines how the labor market for directors and directors' reputational concerns affect corporate governance. We develop a model in which directors can influence corporate governance of their firms, and corporate governance, among other things, affects firms' demand for new directors. Whether the labor market rewards directors for having a reputation of being shareholder-friendly or management-friendly is endogenous and depends on the aggregate level of corporate governance. We show that directors' desire to be invited to other boards creates strategic complementarity of corporate governance decisions across firms. Directors' reputational concerns amplify the corporate governance system in the sense that strong systems become stronger and weak systems become weaker. We derive implications for director appointments, multiple directorships, transparency of the corporate governance system, and board size.
This paper studies informal communications and exit as alternative ways through which investors can influence managers when obtaining control is not feasible or too costly. The first result shows that exit relaxes the tension between investors and managers, and thereby enhances the effectiveness of communications as a form of shareholder activism. The second result shows that public communications are more effective than private communications if and only if managers are concerned about the stock price and their decisions are observed by the market. Overall, the analysis relates the effectiveness of communications to market liquidity; entrenchment and compensation structure of managers; and investors' expertise, investment horizon and ownership size.
This paper studies the optimal structure of the board with an emphasis on the expertise of directors. The analysis provides three main results. First, the expertise of a value-maximizing board can harm shareholder value. Second, it is optimal to design a board whose members are biased against the manager, especially when their expertise is high. Third, directors' desire to demonstrate expertise can shift power from the board to the manager on the expense of shareholders. In this sense, the "friendliness" of the board is endogenous. The effect of these reputation concerns is amplified when the communication within the boardroom is transparent.
This paper studies the advisory role of the board in takeovers. Corporate boards can alert target shareholders when a takeover offer is inadequate and assist them to coordinate their collective decision. The analysis relates the characteristics of the bidder and the target firm to the influence the board has on target shareholders and the value of their shares, and shows that they can both increase with the board's bias. Importantly, the board can be influential even if in equilibrium its recommendation is uninformative and ignored by shareholders. The analysis also provides a novel rationale against the use of takeover defenses.
