Is U.S. CEO Equity and Cash Compensation Aligned with Agency Theory to Maximize Shareholder Returns?

Recent international studies on CEO pay in Europe, Japan, and South Korea reveal significant differences from the U.S. in the use and effectiveness of equity-based CEO compensation, raising questions about the ability of conventional contracts based on agency theory to align with actual CEO compensation practices. Our study contributes to this debate by evaluating nine hypotheses from an extended principal–agent framework in which CEO equity and cash incentives are jointly determined in the shareholder return-maximizing contract. The extended model also incorporates the noisy market valuation relationship between firm income and its market equity value, and distinguishes between firm ‘business risk’ and ‘equity risk’. Our empirical results show that CEO cash incentives increase with firm growth prospects and equity risk and decline with firm business risk and firm scale as predicted by the model; meanwhile, CEO equity incentives are partially consistent. Overall, given the dominance of equity compensation in U.S. CEO pay, our results show that cash pay tied to firm business performance (e.g., operating cash flow) is efficient and plays an important role in aligning CEO and shareholder interests and reducing corporate governance risks associated with agency misalignment.
