Sometimes you hear something that sounds so much like common sense that you end up missing how it overturns everything you were actually thinking, and points in a far more interesting and disturbing direction. That’s how I’m feeling about the coverage of a recent paper on student loans and college tuition coming out of the New York Federal Reserve, “Credit Supply and the Rise in College Tuition: Evidence from the Expansion in Federal Student Aid Programs,” by David Lucca, Taylor Nadauld, and Karen Shen.
They find that “institutions more exposed to changes in the subsidized federal loan program increased their tuition,” or for every dollar in increased student loan availability colleges increased the sticker price of their tuition 65 cents. Crucially, they find that the effect is stronger for subsidized student loans than for Pell Grants. When they go further and control for additional variables, Pell Grants lose their significance in the study, while student loans become more important.
There’s been a lot of debate over this research, with Libby Nelson at Vox providing a strong summary. I want to talk about the theory of the paper. People have been covering this as a normal debate about whether subsidizing college leads to higher tuition, but this is a far different story. It actually overturns a lot of what we believe about higher education funding, and means that the conservative solution to higher education costs, going back to Milton Friedman, will send tuition skyrocketing. And it ends up providing more evidence of the importance of free higher education.
