It’s the perceived value. Masters in Lit is not likely to generate a great salary post grad. MBA had better or they’ve wasted the degree.
At many schools actual unit/hour/credit must be priced the same, but the additional fees vary wildly. Other schools allow the business school to set the price for units.
Also, business school faculty are typically more expensive. A Business School program is more expensive to run than other (non R&D/Lab) departmental Master Programs. Starting salaries for Finance Faculty have to be at least not-crappy when compared to the Wall Street/PE/Hedge Fund base salaries.
BSchool pricing makes a good business case study.
