Price discrimination is an old story wrt private colleges and universities (in terms of it being recognized and studied),;
The interesting development is that as state support for higher education has decreased in many states, many affected public institutions have also turned to increasing use of price discrimination strategies, most typically seen in merit scholarship-type price reductions offered to OOS applicants. As long as the incoming student is paying above the marginal cost of providing the education, this helps the institution with improving revenues.
