Editorial commentary

Endowment income is a major source of restricted and unrestricted funding for large research universities (Harvard, Yale, Oxford colleges, Stanford) and for foundation grant-making programmes. Spending is governed by donor restrictions, fiduciary duties, and board-set spending rules (typically a smoothed percentage of the trailing multi-year endowment value). Endowment income is a critical input to discretionary funding, named chairs, named research centres, and bridge funding pools.
