I investigate the impact of Say on Pay (SOP) voting on CEO compensation in the U.S. The results show that prior year’s SOP against rate, prior year’s voting recommendation from Institutional Shareholder Services (ISS), and the frequency of SOP voting are negatively associated with the growth rate of the CEO compensation respectively. Besides, I apply the two-stage least squares method (2SLS) to mitigate the endogeneity problem and the results are inferentially similar to my main results. Overall, the findings of this study suggests that SOP voting mitigates the excessive growth of the CEO compensation.
