<p>Nice-try:</p>
<p>Actually very few schools outside of HYPSM have the endowment to admit an unlimited number of students on financial aid. All colleges (including HYPSM) have a financial aid budget that they try to stick to at the beginning of each admissions cycle. When that budget starts running out, they will definitely favor full freight students as opposed to those with heavy financial needs. </p>
<p>Most endowment funds are restricted funds meaning they have to be allocated for specific purposes such as funding a new department, a new building, a research program as specified by the donor. Most large contributions are effectively restricted. The smaller contributions from alumni are typically those that make into the unrestricted pools. </p>
<p>I know for fact that several Ivy League schools are currently scrambling to match the aid program announced by Harvard in the fall and subsequently emulated by Yale, Stanford, Princeton and MIT. When you ponder the fact that the annual endowment increase at Harvard is greater than the TOTAL endowment at Brown for instance, you realize that few colleges can truly compete with the big boys. A billion dollar endowment may sound like a big number on paper, but funding a new state of the art science building for instance, which may be required to attract top faculty and research dollars can easily cost several hundred million dollars. Most colleges will want to fund any increase in operating expenses such as financial aid from the interest accrued by the endowment not from the principal. </p>
<p>Much of the colleges endowments are also tied up in long term investments that cannot be easily be liquidated. With big positions in stocks and real estate, many endowments are currently taking a beating. Many have invested in heavily leveraged hedge funds some of which have collapsed. The major growth in endowments from the past few years has come to an abrupt halt for many colleges and the road ahead looks very rough.</p>
