After controlling for size, sector and other firm and executive characteristics, CEOs in the US earn 45% higher cash compensation and 190% higher total compensation. The calculated effective ownership percentage in the US implies that the median CEO receives 1.48% of any increase in shareholder wealth compared to 0.25% in the UK. The differences, can be largely attributed to greater share option awards in the US arising from institutional and cultural differences between the two countries.
