This is purely, purely anecdotal and anecdote is not the plural of data, but my wife is in the early stages of the recruitment process for a faculty physician position at UNC, and the salary range they shared- even before any eventual potential post offer negotiation, signing bonus, relocation bonus, etc.- was every bit as competitive for her specialty as some private practice offers she has entertained. We were actually really pleasantly surprised because in general, academic medicine pays a little bit lower than private practice medicine, and also because UNC does have a reputation of paying below market value. The other thing is that at it appears that UNC does a fantastic job with the non-salary benefits stuff too.
I don’t have any idea about general university academic faculty salar ies and how they compare at UNC to our peers, but I do know that I’ve read that UNC has been losing key faculty members to schools like Duke, Emory, UVA, Johns Hopkins, Northwestern, etc. because of compensation.
