Fwiw, I remember reading an ad fairly recently from a middle eastern university that specified a salary equal to the current AACSB average + 25%, w/ the usual additional benefits on top of that (e.g., housing, annual two-way airfare, health / life insurance, professional memberships, conference attendance expenses, assistance with children's tuition, etc.).
Now, I've no idea if "AACSB average" refers to U.S. AACSB averages or the lower Int'l AACSB averages, research institution averages or 3/3 institution averages, public or private averages, etc.; perhaps they're referring to the flat out 'grand' average of all schools responding to the AACSB's annual survey.
I did quickly look for that specific ad so that I could offer you a link, but I could not find it. (I usually peruse the ads here, in the Chronicle's 'Jobs' classified section, and also at HigherEdJobs.com and the Academy of Int'l Business site. It's possible the ad was pulled, but I assume I just missed it.)
Here's an ad I did find, that pays less. They claim to be AACSB competitive (no 25% premium) and specifically list salaries from $70-130k. With your publication record, I'd hope you might get something closer to $130k, but that may be a naive assumption.
http://www.higheredjobs.com/search/details.cfm?JobCode=175488105If that assumption does happen to be fairly realistic, though, and if that income is tax exempt locally, w/ the first $90k or so also exempt from U.S. taxes, you'd probably do quite well on an after-tax basis. (For example, say $140,000 earned in the U.S. is roughly equivalent to $90k after federal income taxes. $130,000 abroad might be worth $125,000 or so after U.S. federal income taxes, assuming no local income tax. And any offer of, say, $95k or up might actually net you more money, after tax, than you currently make.)
If you're interested, and don't already have a copy, 2010 AACSB averages can be found here, on p. 35 (I assume this is all respondents, btw, not just 2/2 respondents):
