An examination of the executive compensation structure of 153 randomly
-selected manufacturing firms in 1979-1980 provides evidence supportin
g advocates of incentive compensation, and also suggests that the form
rather than the level of compensation is what motivates managers to i
ncrease firm value, Firm performance is positively related to the perc
entage of equity held by managers and to the percentage of their compe
nsation that is equity-based. Moreover, equity-based compensation is u
sed more extensively in firms with more outside directors. Finally, fi
rms in which a higher percentage of the shares are held by insiders or
outside blockholders use less equity-based compensation.
