The results of this intra-industry study p rovide provocative comparisons with previous
research findings. Some of the results here match previous work, others do not. This
could be due to the fact that the industry chosen here has some unique characteristics
that previous research did not uncover because a vertical sample was used here while
previous research sampled from a cross-section of many industries. The differences
also could be attributed to different economic and environmental conditions today and
the early 1990s. Whatever the reason for the differences and similarities, we can only
report that they exist and only speculate on the reasons why.
