Based on course offerings, CMC’s economics department has a fairly strong pre-professional emphasis. You can compare the CMC economics offerings to those at Pomona, which has are more traditional liberal arts / pre-PhD emphasis.
Note that economics at less selective schools may be more likely to tilt toward a pre-professional emphasis, particularly if there is no actual business major. But some more selective schools without actual business majors may have some more pre-professional type offerings.
Remember that business is the application of various social studies fields like economics, sociology, psychology, as well as some math and statistics. So a student at a school without a business major could take applicable courses in those departments to get some background in the topics normally associated with business.
Note that MBA programs do not require a specific undergraduate major, but the more selective ones tend to prefer students who have good post-BA/BS work experience.
