Question
1. The following equation was estimated using the data in CEOSAL1:
log(salary) = 4.322 + .276 log(sales) + .0215 roe – 00008 roe?
(.00026)
(.324) (.033)
n = 209, R? = .282.
(.0129)
This equation allows roe to have a diminishing effect on log(salary). Is this generality necessary? Explain why or
why not.
