Will money managers increase diversity?

"David Swensen is the veteran investment chief of Yale University’s $31.2 billion endowment. Earlier this month, he told the dozens of firms that manage Yale’s money they would be measured on their progress increasing the diversity of their investment staffs" (WSJ Oct. 2020).

Let's conduct a thought experiment. Suppose that the executives face incentives that encourage them to maximize returns on the money they manage. 

1. If executives know that diversity increases returns, would Yale need to measure progress on increasing diversity? Would the threat of moving to another company align the interests of Yale and the money managers?
2. Under what conditions would the threat compensation improve the alignment the interests between Yale and the money managers?
3. Under what conditions would the mandate and compensation misalign the interests?
