@sgopal2 The first one is is actually a negative. Harvard’s endowment went from 26 billion in 2005 to 36 billion in 2015. Yale’s has gone from 15 billion to 24 billion. Stanford from 12 billion to 21 billion.
If we talk about peer schools, Columbia from 5.2 to 9.2, CMU from 0.8 to 1.6, Dartmouth from 2.7 to 4.4, Penn from 4.3 to 9.6. Duke is nothing special in those terms. In fact, the endowment increase has been absolutely minimal.
