Tyler Cowen:

There are a lot of numbers, but here is the comparison I find most impressive: Adjusting for grants, rather than taking sticker prices at face value, the inflation-adjusted tuition cost for an in-state freshman at a four-year public university is $2,480 for this school year. That is a 40% decline from a decade ago…

As might be expected, the trajectory for student debt is down as well. About half of last year’s graduates had no student debt. In 2013, only 40% did. That famous saying from economics — if something cannot go on forever, it will stop — is basically true. Due to changes in the formula, aid for Pell Grants is up, which helps to limit both student debt and the expenses of college.
