Note(s): *Significance level p ≤ 0.10, **Significance level p ≤ 0.05, ***Significance level p ≤ 0.01
aIntercept for the smallest company in the reference industry (Energy) with log of income equal to 9.6588
bThis coefficient would be applied to the difference between the log of the company’s size and 9.6588
Key: Expected Direction = Expected Sign; “+ve” = positive; “ −ve ” = negative; “?”: direction is unpredictable
