As I have mentioned before, there appears to be no official "meat market" for legal studies positions in business schools. I found my current job through Higher Ed Jobs, and thought Higher Ed Jobs was the best source during my search. Also, the Chronicle of Higher Education's Vitae recently launched (though they have had a jobs board for quite some time) and is likely worth frequenting.
For those still on the market, I wanted to highlight two recent business law postings: Southeast Missouri State University and University of Alaska (Fairbanks). Both positions appear to be tenure-track legal studies positions in business schools. Also, both schools are AACSB-accredited. (There are multiple accrediting bodies for business schools, and AACSB is the gold standard).
I maintain that being a professor is the best job in the world (especially given that my childhood dream of becoming an NFL quarterback is looking less glamorous in light of all the talk about concussions and chronic traumatic encephalopathy (CTE)).
Wishing success for our readers who are on the professor market.
