Why Tuition Outruns Inflation: Cost Disease, Aid, and State Retreat

The companion calculator projects today's tuition forward at an inflation rate you choose. The reason it needs a rate higher than general inflation, and the reason families are told to assume tuition climbs faster than the cost of everything else, is a genuinely interesting economic puzzle. College is a service that has resisted the productivity gains that made most goods cheaper over time, and several forces push in the same direction. Understanding them helps you pick a realistic projection rate and see where the money actually goes.

Cost Disease: The Core Explanation

The most fundamental reason is an idea economists call Baumol's cost disease. In manufacturing, technology lets a worker produce far more per hour than a generation ago, so wages can rise without prices rising. Teaching resists this: a seminar of fifteen students still needs an instructor for the same hours it did decades ago. Productivity barely rises, yet salaries must keep pace with the wider economy to attract talent, so the cost per student inexorably climbs. Labor-intensive services, education, healthcare, live performance, all suffer the same disease, which is why their prices outrun general inflation year after year.

The Administrative Explosion

A second force is what colleges spend on beyond instruction. Over recent decades, staffing in administration, student services, technology, compliance, counseling, and amenities has grown faster than teaching faculty at many institutions.

Some of this spending genuinely serves students; some reflects an amenities arms race, where schools compete on climbing walls and lavish dorms to attract applicants. Either way, it lands in the price.

The State Retreat

For public universities specifically, much of the tuition increase is a shift, not an increase, in total cost. As state legislatures cut per-student appropriations, especially after recessions, universities replaced the lost public funding with tuition. From the student's side it looks like a soaring sticker price; from the university's side, total spending per student may have barely moved, the burden simply migrated from taxpayers to families. This is why public-college tuition often spikes hardest in the years after a state budget crisis.

The Bennett Hypothesis

A more contested idea holds that readily available financial aid itself enables higher prices. Named for a former education secretary, the Bennett hypothesis argues that when students can borrow more, colleges face less resistance to raising tuition, capturing part of the aid in higher prices. The evidence is mixed and the effect varies by sector, but the intuition is straightforward: subsidize demand for a good in limited supply, and some of the subsidy shows up as a higher price rather than more access. It is one reason tuition and aid have risen together.

Choosing a Realistic Projection Rate

These forces are structural, not temporary, which is why planners routinely assume tuition rises a few points faster than general inflation. When you set the rate in the calculator, lean toward the historical college-cost trend rather than the consumer inflation figure, and consider running a slightly higher and slightly lower rate to bracket the uncertainty. The projection is only as realistic as the rate you feed it, and cost disease suggests that rate stays stubbornly above ordinary inflation.
