I can only comment on accreditation for Econ departments as not being meaningful. Let’s go through a lengthy process to get accredited and this will improve the quality of our Econ major said no econ professor ever. Perhaps it means something more for accounting departments. For business schools overall, one thing accreditation brings is increased attention on who is teaching the courses. A certain percent have to have PhDs and faculties can’t rely too heavily on local business professionals to teach a lot of the courses. This has in the past been a bigger deal for small colleges with business Programs. Presumably there might be more uniformity across accredited accounting programs in required courses for a degree. These things are less relevant for Econ departments.
