This paper examines the effects of growth opportunities and monitoring mechanism on the sensitivity of CEO compensation to performance measures. Our results are based on 1996~ 1999 CEO compensation data from companies listed on the Taiwan Stock Exchange. We find that the sensitivity of CEO pay in growth firms is significantly higher than that in other firms. In addition, we find that in large firms, the monitoring mechanism and the sensitivity of CEO pay are complementary mechanisms, while the monitoring mechanism is a substitute for the sensitivity of CEO pay in small firms.
