Tables 9 and 10 present the Model 2 regression results using the subsamples for 2007 and 2008, respectively.
13 The results show a significant negative relationship between corporate governance and audit fees
in the moderate growth sample for both 2007 and 2008. The coefficients for both years are near 10%. This
relationship is insignificant in the negative growth and overly fast growth subsamples. The sign of Gov is
inconsistent between the two samples, possibly because corporate governance and corporate growth have
opposing effects on audit fees. In other words, audit risk’s positive effect on audit fees in negative and overly
fast growth firms offsets the negative effect of corporate governance on audit fees to some extent. For this reason,
we observe a mixed and insignificant result.
