[We compute and compare risk-adjusted CEO pay in the United States and United Kingdom, where the risk adjustment is based on estimated risk premiums stemming from the equity incentives borne by CEOs. Controlling for firm and industry characteristics, we find that U.S. CEOs have higher pay, but also bear much higher stock and option incentives than U.K. CEOs. Using reasonable estimates of risk premiums, we find that risk-adjusted U.S. CEO pay does not appear to be large compared to that of U.K. CEOs. We also examine differences in pay and equity incentives between a sample of non-U.K. European CEOs and a matched sample of U.S. CEOs, and find that risk-adjusting pay may explain about half of the apparent higher pay for U.S. CEOs.]

ABSTRACT This paper examines when information asymmetry among investors affects the cost of capital in excess of standard risk factors. When equity markets are perfectly competitive, information asymmetry has no separate effect on the cost of capital. When markets are imperfect, information asymmetry can have a separate effect on firms’ cost of capital. Consistent with our prediction, we find that information asymmetry has a positive relation with firms’ cost of capital in excess of standard risk factors when markets are imperfect and no relation when markets approximate perfect competition. Overall, our results show that the degree of market competition is an important conditioning variable to consider when examining the relation between information asymmetry and cost of capital.
