Question
Would you include ros in a final model explaining CEO compensation in terms of firm performance?
Consider an equation to explain salaries of CEOs in terms of annual firm sales, return on equity (roe,
in percentage form), and return on the firm's stock (ros, in percentage form):
log(salary) = Po + P₁ log(sales) + B₂roe + B3ros + μ
Using the data in CEOSAL1, the following equation was obtained by OLS:
log(salary) = 4.32 +0.28 log(sales) + 0.0174roe + 0.00024ros
(0.0041) (0.00054)
(0.32) (0.035)
n = 209, R² = 0.283
