Now Swat adds one student, a full payer. They were going to have 1450 students, but at the last minute, the school decided they really wanted this student. The student is a full payer. Does Swat lose $30,000 (the subsidy) on this student?

<p>Yes. It's called "diluting the endowment".</p>
<p>Of the $73k per student Swarthmore spends, only $29k comes from the average student in tuition, room/board, fees. $44k comes from other sources ($36k from endowment returns and $8k from annual giving, grants, and miscellaneous revenue).</p>
<p>To the extent that you can add students without increasing costs (more professors, more dorms, more health care, etc.) each incremental student increases the bottom line. But, with Swarthmore's 8:1 student/faculty ratio, as soon as you add eight incremental students, you have to add a professor or allow the quality to decline (student/faculty ratio being a huge component of Swarthmore's "quality).</p>
<p>As a result of this math, many schools understand that, to improve their financial position, they need to decrease enrollment. For example, Oberlin currently believes that they are spending too much from the endowment. So, their strategic plan includes reducing enrollment by 100 students.</p>
<p>Likewise, Williams College found that its endowment had been eroded by the near doublind in size of the student body with the arrival of women between 1970 and 1980. This was noted in their strategic planning and they have corrected it (quite nicely, I might say) by not increasing enrollment by even 1 student over the last decade.</p>
<p>As you are probably expecting, there's an Economics paper on this very topic, which I would be glad to link for you when the Williams website when these higher education financing papers starts working.</p>
<p>Suffice to say, that's the reason that all of these big endowment colleges don't expand in the face of increased demand. "Per student endowment" is the whole enchilada in college finance.</p>
