Columbia reported the following initial compensation for their most recent class (employment report pdf can be found on their website):
Investment Banking/Brokerage: $80k-$300k - 32.5% of class
Investment Management: $85k-$300k - 11.3%
PE/VC/Buyouts: $99k-$575k - 4.4%
Real Estate: $85k-250k - 5.5%
These include guaranteed bonuses, and not discretionary bonuses. It's definitely possible that many IB/IM types made substantially more in discretionary bonuses last year because the industry experienced a record year.
Also, as far as I know, Harvard and Stanford do not release their employment data; so the reason why you have not seen higher initial compensation numbers from them is because it hasn't been published. I will say that Stanford sends a large group into the local VC community and compensation is through the roof. Harvard also sends a sizable group into the Boston VC industry.
