good insights, pelihu. Actually, this past october, the UC Regents is allowing all UC professional schools (thus Haas and Anderson) to control their own tuition rates and their money to a greater extent (the details I do not know right now and will have to find out hopefully at Super Saturday). I think the main goal is exactly what you said (and what Darden has done), to increase autonomy to compete with the private schools out there.
I was looking up some endowment information, and Haas seems to have $200+M at the moment, not bad as a per capita number (of course, nothing compared to Darden), but UCLA seems to have a pitifully low $60+M endowment. Tuck actually only has about $200M according to Wikipedia, I wonder why it has the ability to recruit all the great faculty.
Anyway, the future looks brighter for Haas and Anderson with the break-off from UC policies. I know Haas is going to increase its student population once they build the joint business-law school building on campus. Anderson still has a lot of excess capacity, as evidenced in their recent expansion from 300 to 340 students 3-4 years ago. I heard from the students that there are still plenty of rooms for study/group projects/classes on campus.
