Skaber overselvsikre CEO’er et højere afkast for aktionærerne – eller det modsatte?

“In our recent paper, Restraining overconfident CEOs through improved governance: Evidence from the Sarbanes-Oxley Act, forthcoming in the Review of Financial Studies, we use the joint passage of the Sarbanes-Oxley Act and changes to the NYSE/NASDAQ listing rules to analyze the impact of improved governance in moderating the behavior of overconfident CEOs. Overconfidence can lead managers to overestimate returns and underestimate risk. The literature suggests that while some CEO overconfidence can benefit shareholders, a highly distorted view of risk-return profiles can destroy shareholder value. An intriguing question is whether there are ways to channel the drive and optimism of highly overconfident CEOs while curbing the extremes of risk-taking and overinvestment associated with such overconfidence. We explore such a possibility in this paper. Specifically, we investigate whether appropriate restraints on CEO discretion and the introduction of diverse viewpoints on the board serve to moderate the actions of overconfident CEOs and, in the end, benefit shareholders.”
