The empirical literature on executive compensation generally fails to
specify a model of executive pay on which to base and test hypotheses
regarding its determinants. In contrast, this paper analyzes a simple
principal-agent model to determine how well it explains variations in
CEO incentive pay and salaries. Many findings are consistent with the
basic intuition of principal-agent models that compensation is structu
red to trade off incentives with insurance. However, statistical signi
ficance for some of the effects is weak, although the magnitudes are l
arge. Also, there is little evidence of the use of relative performanc
e pay. Nevertheless, while puzzles remain, it seems clear that princip
al-agent considerations play a role in setting executive compensation.
