[3] But what makes it particularly valuable is that it directly compares the impact of reducing sticker prices versus increasing
institutional spending per student — and does so using a rigorous methodology that allows an estimate of causal effects, rather than just correlations between tuition, institutional spending, and student outcomes.
Putting all of this together, the authors find that a 10 percent increase in
institutional spending per student leads to a 3 percent increase in enrollment and even larger percentage increases in degree completion one to three years later.
