Idiosyncratic volatility, executive compensation and corporate governance: examination of the direct and moderate effects

摘要

Entrenchment of private benefits by the CEO or dominant owners can lead corporations to avoid riskier but more private benefits resulting in greater idiosyncratic volatility and information flow trading. Using a unique database of 806 listed firms, we investigate the impact of CEO compensation and corporate governance on idiosyncratic volatility and information flow trading. We find strong and robust evidence that equity-based (fixed income) CEO compensation is negatively (positively) related to volatility and information trading. Incorporating an agent principal-principal perspective into our models of managerial discretion provides us with an accurate prediction of how the proportion of CEO compensation and the degree of entrenchment will influence risk-taking decisions as well as how equity-based compensation interacts with related-party transaction and ownership dispersion to influence stock volatility. Finally, we find that idiosyncratic volatility and information flow trading are also affected by CEO compensation and corporate governance, which act as instrumental variables, while subject to environmental variants and the jointly determined.
