This paper investigates the role of accounting earnings in top executi
ve compensation contracts. It provides evidence in support of the hypo
thesis that earnings-based incentives help shield executives from mark
et-wide factors in stock prices. The paper demonstrates that earnings
reflect firm-specific changes in value, but are less sensitive to mark
et-wide movements in equity values. As a result, the inclusion of earn
ings-based performance measures in executive compensation contracts he
lps shield executives from fluctuations in firm value that are beyond
their control. The hypothesis is shown to explain cross-sectional vari
ation in the use of earnings-based incentives.
