The Study That Got Halfway There

A new college-value study making the rounds fixed three flaws skeptics spent years flagging, then stopped before the money math. Discount its own headline number at my 7.8 percent rate and $86,806 becomes about $24,800. The debate is not over. It finally has its real starting point.

A new study of college value is making the rounds, and the people sharing it are calling it the end of the debate.

The Postsecondary Commission hired the policy research firm Mathematica to measure what enrolling in a Texas public college adds to a student’s earnings.[1] The researchers linked the school records, college records, and paychecks of hundreds of thousands of Texans. The headline finding: students who enrolled seeking a bachelor’s degree came out $86,806 ahead after fifteen years.

The posts write themselves. College pays. The skeptics should apologize.

I read all 126 pages. Here is what I found.

This is the best at-scale study of college value I have seen. I mean that without qualification. The authors fixed three of the flaws I have spent years documenting in the famous numbers. And the victory lap being run on its behalf still gets the study wrong, because the authors stopped at the halfway point. They measured the earnings difference with real care. They never ran the investment arithmetic. Run that second half on their own numbers and the comfortable headline becomes a conditional one: real value for many students, decided by program, completion, and price, and much smaller than $86,806 the moment you treat money the way money works.

Let me show you both halves.

The half they fixed

The numbers families usually get handed, the $1.2 million lifetime premium and its cousins, share three defects. They compare graduates to non-graduates without asking whether the two groups were similar to begin with. They count only the people who finished. And they ignore the years of earnings a student gives up while enrolled.

This study repairs all three. It compares each entering cohort to a matched group of similar Texans who did not enroll, matched on age, prior schooling, and home county, and checked for balance on test scores, family income status, and prior earnings.[2] It counts the students who started and never finished, alongside the graduates. And it starts the meter in the year of entry, so the earnings surrendered during the college years count against the degree.

Then the authors did something genuinely useful. They measured what happens when you skip the matching, the way the marketing numbers do. The answer: for students entering in 2008–09, the unmatched comparison inflated the bachelor’s earnings gain by a third. For associate’s degrees the inflation was 77 percent. For certificates it was 98 percent.[3]

Stop and absorb that. The most rigorous study on the pro-college side of the ledger that I know of, funded by the Gates Foundation and the ECMC Foundation, just priced the head start that a raw comparison builds in, what researchers call selection bias, at a quarter to a half of the gain that comparison claims.[1]

Students who go to college would likely have out-earned the average non-student anyway. Comparing the two groups raw credits the college with what the student brought to campus. That argument used to get me called a cynic. It is now a finding, printed in the appendix of the study everyone is celebrating.

The half they skipped

So why not take the $86,806 at face value?

Because that number is a raw sum.

The study adds up earnings differences across fifteen years in inflation-adjusted dollars and reports the total.[4] A dollar received in year fifteen counts exactly the same as a dollar today.

Investors, lenders, and pension funds do not treat money this way, and neither does the federal government’s own guidance for weighing an investment’s costs and benefits. For most of the past three decades, and again today, its rule of thumb for judging investments has been 7 percent a year after inflation, because that is roughly what private money earns elsewhere.[5] My model uses 7.8 percent, set near that benchmark, a choice I defend at length in A Degree Is Not a Treasury Bond.

I rebuilt the study’s year-by-year stream from its own Exhibit 1 and discounted it. At a 3 percent rate, below today’s federal student loan rates, $86,806 becomes about $55,300. At my 7.8 percent rate it becomes about $24,800, and the break-even point slides from year ten into year eleven.[6]

Texas Study at Various Rate Assumptions: First Adjustment

The deflation does not stop there. The earnings in the study are pre-tax, straight from unemployment insurance wage records. The extra earnings college brings are taxed, and the tax code takes a bigger bite of bigger paychecks, so the students lose more to taxes than the workers they are compared against. A family keeps the after-tax difference, not the printed one.

The study is even gentler on the cost side. It subtracts tuition, fees, and books, net of every grant and waiver the student received, and nothing else.[7] To be fair, the authors make a defensible choice on room and board. People pay to live whether or not they enroll, and the researchers could not observe housing costs cleanly, so they left them out rather than guess. I accept that reasoning as far as it goes. But the study also counts every cost at face value, as if families paid cash. The family that borrows at today’s federal rates, 6.52 percent for undergraduates and up to 9.07 percent on parent loans, pays interest on every dollar it borrows, and that interest is real money the study’s undiscounted total never sees.[8]

One more omission is worth naming, because the authors flag it themselves. The wage records miss employer benefits entirely, the health insurance and retirement money on both sides of the comparison.[9] Which way that cuts is less obvious than it sounds. Benefits go with the employer and the job, not the diploma. A union card, a military career, or a counter job at a chain known for generous benefits all come with packages no credential produced, and in my experience, at a firm that employs both, the standard package does not check for a degree. Whatever benefits gap exists between the two matched groups is unmeasured, in size and in direction. Subtract taxes and the printed gap shrinks. Count benefits and nobody knows. My point is not that every correction cuts against college. My point is that the study ran none of them.

Discounting, taxes, and the cost of borrowed money are what analysts apply to cash flows everywhere else in the economy. The study measured the gain well and then declined to price it.

An average is not the bet your family is making

There is a second, quieter problem with the headline, and you can see it in the shape of the curve.

The study reports that the average bachelor’s entrant hit bottom five years in: down $33,925.[10] Read that as the cost of attending college and it sounds almost painless. Now compare it to the bet made by a student who enrolls full-time and does not work. Four years out of the workforce, at the full-time high school starting wage my model assumes, is roughly $148,000 in forgone earnings alone, before taxes and before the first dollar of attendance costs.[11]

How does a $148,000 bet produce a $34,000 dip in the data? Because the study’s number is a cohort average, and the cohort is not one family. The comparison group earned far less than a full-time wage: the study’s matched non-students made about $53,000 over those four years, partly because anyone missing from Texas payroll records counts as earning zero. The enrolled students earn money while in school, and those earnings offset the gap. And about three in ten across the study’s cohorts did not finish a degree during their follow-up window[12], and those who left school could go back to work sooner, which pulls the average hole shallower. All of that is correct measurement of the group. None of it describes the exposure of one student who enrolls full-time, borrows, and stays the course. The average is a fact about Texas. Your decision is a fact about your kid.

Texas Study Drawdown Comparison

The study’s exhibits show what the average smooths over. Liberal arts and social science majors were still underwater ten years after enrolling and broke even only sometime between years ten and fifteen, before any discounting.[13] About a quarter of certificate-granting institutions were still negative five years out, even before discounting.[14] Students who entered from the bottom quarter of high school math achievement were, on average, $7,668 behind their non-college peers a full decade in, and were ahead of them by year fifteen.[15] The losing end of this range is enrolled, and it is the population the accountability debate claims to protect.

Across every degree type, cohorts in which more students finished a degree had more value, even after the authors accounted for the institution’s size, price, and other traits. For bachelor’s cohorts, each additional point of completion went with about two thousand dollars more value per student, and the same pattern showed up for associate’s degrees and certificates at smaller amounts.[16] Program choice mattered more than institution choice. Which is to say: the study’s own findings put the risk where my book puts it. What you study and whether you finish show up in their analysis. What you pay is subtracted in their own definition of value. Whether college pays turns largely on those three choices, not on the act of enrolling.

The fine print the victory laps skip

Three boundaries, all disclosed by the authors, and none of them in the posts I have seen.

The fifteen-year headline rests on a single entering class: 28,614 students who started in the 2008–09 year at 29 public universities, matched at a 64 percent rate.[17] Their earnings story runs from the financial crisis through the tightest labor market in decades. The authors show that later cohorts track a similar path through year fourteen, and the trade-off is structural, since a long window forces old data. Fair enough. But a 2026 applicant deciding at 2026 prices, in a labor market being rearranged in real time, is not the 2008 cohort, and honest uncertainty about that gap should run in both directions.

The study covers Texas public institutions only. The authors note that prior research suggests private and for-profit colleges show more variable and more frequently negative returns, and they warn readers not to generalize.[18]

And the estimates are sensitive to a quiet choice about missing records. Anyone absent from Texas payroll records counts as earning zero, and anyone with no Texas earnings in the years after college should have ended is dropped from the study. Change only that second rule, and results for each degree type move by anywhere from nearly a fifth to nearly half.[19] The authors report the swing themselves.

What the study proves

Here is the state of the argument after this study, as I read it.

The uncontrolled marketing numbers no longer hold up. A research team funded by college’s own champions has now measured the inflation the skeptics alleged and printed it. What remains standing is a conditional claim: enrolling in a Texas public college added real earnings value for many students, before discounting, before taxes, before borrowing costs, on average, in one state, in one era.

That sentence will not fit on a college-night slide. It fits on a spreadsheet, which is where a six-figure family decision belongs.

The authors got halfway to that spreadsheet, and the half they completed was the hard half. The half they skipped, the money math, requires no administrative data and no matching algorithm. It requires only the willingness to treat a family’s money with the same rigor everyone else’s capital gets. Their study plus that arithmetic equals the argument of my book: the question was never whether college pays on average. The question is when, for whom, at which school, and at what price.

The family asking those four questions is not cynical. It is doing what this study did, and then finishing the job.

For a Texas family, the next step is already public. My model’s Texas summary page prices the state’s institutions at full cost, at typical net cost, and at zero cost. Every other state has a page of its own at collegeroi.org.
