A University's Online M.B.A. Is Less Expensive -- and Purposely Different

Many of the universities that have created lower-priced online graduate programs in recent years have gone out of their way to make the case that the digital versions are equivalent to their (more expensive) in-person equivalents.  Boston University makes no such promises about its new online master's in business administration degree in conjunction with edX, which will cost $24,000 compared to tuition and fees of $56,000-plus for its in-person, full-time version (more than $76,000 with room and board).
