Corporate governance: issues related to executive compensation, corporate boards and institutional investor monitoring

摘要

This dissertation contains five research projects within the context of two distinctive issues that concern the effectiveness of executive compensation in aligning executive interests with shareholders and how institutional investors play a role in structuring corporate governance mechanisms. The objective of this dissertation is to first determine how institutions should exert their influence if they are serious about alleviating agency problems and improving firm performance. Second, the thesis seeks to determine whether institutional investors use their influence to shape executive compensation and corporate governance mechanisms in a manner consistent with aligning managerial interests with shareholders and increasing shareholder wealth. The thesis finds that CEOs with option incentives increase the likelihood that a firm will increase risk by undertaking both major real investments and acquisitions. Moreover, CEO option grants are positively related to measures of firm valuation and operating performance suggesting option incentives are an important mechanism to align CEO interests with shareholders. This is robust to alternative measures of firm valuation and operating performance, also various estimation techniques. Using these findings to motivate the direction of institutional influence on executive compensation, it is found that institutional investors, particularly smaller activist traders, significantly increase option grant incentives received by executives. Institutional influence also raises CEO pay which is consistent with preservation of reservation CEO utility levels. Addressing the role of institutional investors in the context of other corporate governance mechanisms, it is found that institutional investor influence is also negatively related to board size and positively related to board independence, which is achieved by removal of inside directors. Such actions are consistent with empirical studies that show smaller boards and increased levels of independent directors improve firm performance and board decision making.The main conclusion from this dissertation is that option incentives are an effective mechanism to align CEO interests with those of shareholders. Institutional investors appear to recognise this importance, and effectively use their influence to increase options received by executives. Combined with institutional investors putting in place corporate boards that provide better oversight of management, institutional investors appear to be effective monitors of the firms in which they invest.
