Quote from the article: "Generally, the recession has made colleges and universities want to keep undergraduate or professional school enrollments level, or even to increase them. But doctoral education at elite universities operates on a very different economic model. Students are almost always fully supported, so they don't bring tuition dollars with them. And while states provide some support to public universities for graduate education, private universities are more likely to be footing the full bill."
