How much money does a business professor (with a PhD) expect to earn
each year at an American college or university?  I've found websites
listing faculty salaries averaged across all majors, but none that
specifically list business PhD salaries.  I'd also like to get an idea
of how much they normally earn each year from outside sources
(consulting, journal articles, etc.).  Also, how much of a difference
in faculty pay is there among the various business subjects (finance
vs. marketing vs. manangement, etc.)?

My ideal answer would be something like
http://chronicle.com/free/v50/i33/33a01301.htm, geared toward
business, and listing average outside compensation.  And it would
explain the differences in pay among business subjects.

But any answer that provides a realistic estimate of the total annual
compensation for both assistant and full professors of business at
both prestigious and non-prestigious colleges/universities will be
sufficient.

Thanks

Because many states have public employee salaries posted (or
available), you might try to look for your information this way.  The
top tier public schools pay competitively with what the privates
pay--at least for faculty who are in demand and for new faculty.

I believe the order is Finance > Accounting >> Management > Operations
> Marketing  but that might vary from institution to institution.

Oh, and there is "off budget" salary that comes from the research
account. This might be as small as $1500/year, but can be much, much
larger for top faculty.  This can be used for books, office, postage,
travel, grad students, conferences, or electronic gadgets.
