kwam - I see where you are coming from but it is difficult to argue there is such a trend.
LBS is in there because of a Europe skew more than anything. They contact alumni to fill out surveys - I would bet most UK based alumni would be more interested in contributing to the FT than BW or whatever. LBS always shines high in the FT.
NYU is a funny one with the FT. The others are standard high performers. Wharton gets tradition on its side more than Finance, GSB will probably feel maligned with its ranking here. Stanford & Harvard are management and never rank at all for Finance.
What is more interesting are the uncharacteristic showings. Columbia is always low on alumni recommendations, which is weird. If you want value for money, Coppead in Brazil (62nd) is your school! Only non-US schools seem to rank high on International mobility, which maybe reflects on the motives of those outside the US persuing MBAs.
There is nothing in their first derivative data set that links to Finance - they will doubtless protect their algorithm to calculate the ranks (I know that the schools will have first seen this the same time as me. Well, maybe later, I was in early).
Maybe I will do a regression analysis on what data each table shows to get you the basis of their calculation (obviously lacking non-shown data).
I am sad, aren't I.
