Update on University of Michigan

The University of Michigan business school is not in this years's Forbes rankings because it declined to participate in the survey. Forbes did not make a mistake.

Forbes MBA Survey: Why Is Ross Unranked?
You may have noticed that Ross is not included in this year's Forbes ranking of full-time MBA programs. There's a simple reason for that: We declined to participate in the survey.Unlike surveys managed by such publications as BusinessWeek, The Wall Street Journal, and The Financial Times, the Forbes survey is concerned almost exclusively with a financial calculation of return-on-investment. We are certainly aware of the financial commitment made by our students. We also recognize that ROI is a factor to consider when evaluating an MBA program. However, we don't believe that an ROI calculation, by itself, is the most meaningful way to measure the full value of an MBA program. A world-class education is more than an economic transaction. The excellence of our full-time MBA program manifests itself in many ways: the distinctiveness of our action-based learning programs; the quality of instruction; the breadth and depth of our research; the esteem in which top recruiters hold our graduates; and, of course, the talent and commitment of our students and alumni.

Fair enough. I'm still wondering about the Economist though.
