<p>You really have to look at each school in detail to understand their pricing strategy and distribution of financial aid discounts. Some details to look at would include percentage of students qualifying for need-based aid and the average amount of that aid, the percentage of students receiving merit aid and the amount, the percentage of low income students (Pell Grant) and so forth.</p>
<p>Need-based aid tends to favor lower income students (although certainly not exclusively). Merit aid tends to favor wealthier students (because it typically requires high SAT scores). A high sticker price and signficant need-based aid would tend to be a more progressive pricing policy: sticking it to the rich to fund lower income students. Haverford, Wellesley, Smith, and Swarthmore are all examples of progressive pricing and they all have quite a bit of diversity as a result (along with a lot of wealthy students).</p>
<p>A lower sticker price (within this tier of schools) tends to be a less progressive pricing structure because the wealthiest full-fare customers pay a lower price, especially when combined with large amounts of merit aid. Davidson is an example of this and the result is a student body with relatively little diversity.</p>
<p>Of course, you really can't look at just one side of the equation (price) without looking at the other (per student operating expenditures). In other words, you have to look at what you are paying and what you are getting. The difference is, in effect, an across the board hidden merit discount funded primarily by the endowment. Schools with very high operating spending (big endowments) tend to have large numbers of applicants (for obvious reasons) and, therefore, very high admissions selectivity. </p>
<p>There is a much larger spread between schools on the expense side. The biggest single component of per student operating expense is faculty and staff salaries.</p>
