How to use this pack

Help the reader explore this rabbit hole. Start by asking what caught their attention, then discuss one question at a time. Explore the strongest counterargument and what remains uncertain. Distinguish the original speakers’ claims, Adam’s question, the site’s research commentary, and your own interpretation. Do not treat the commentary as a transcript or assume Adam endorses every claim. Preserve corrections and uncertainty; do not invent sources or pretend to have opened links.

This pack contains the page’s current research text, references and figure text. Related rabbit holes are linked, not included. It is a reading companion, not an independently verified source.

The short version

There is a strong cross-country relationship between how much students actually know (test scores) and how fast an economy grows. Hanushek and Woessmann call this “knowledge capital,” and their central finding is that once you use test scores instead of years of schooling, most famous puzzles stop being puzzles — the East Asian miracle and the Latin American growth disappointment both fall onto the line. Two mechanisms are usually offered for the countries that stay off the line: resource rents that out-earn a country’s skills (the Gulf), and skills that cannot reach a market — landlocked, blockaded, or badly governed. ⚠ The country lists on this page are illustrations of those mechanisms, not the output of a residual analysis; nobody here has fitted the model and ranked what falls out of it. Armenia, which prompted the question, is offered as a case of the second mechanism on that basis.

ACEMOGLU: Yes, exactly. Kasparov. It has disappointed. Armenia has really disappointed. It has underperformed economically. It had a good start in terms of building democracy, and then it’s squandered that. It still has that human capital focus, but the situation is very difficult. It’s squeezed between Russia, Turkey, and Azerbaijan. Turkey is now finally perhaps going to start allowing trade and other things with Armenia, but it’s not always.

Research commentary

Adam asked: “What are the outliers for education to economic performance? Meaning what countries are under and over performing economically compared to the educational quality.”

The finding to know first

Eric Hanushek and Ludger Woessmann, The Knowledge Capital of Nations (MIT Press, 2015):

Substitute cognitive skills measured by international tests (PISA, TIMSS) for years of schooling, and the fit to long-run growth improves dramatically.
Years of schooling turns out to be a poor proxy. Two countries can each average 11 years and differ enormously in what students learn — Armenia is a case in point, see below.
Their headline claim: the “Latin American growth puzzle” and the “East Asian miracle” both dissolve once you condition on skills. Neither was mysterious; both regions grew about as fast as their knowledge capital predicted.

That last point reframes Adam’s question. The interesting cases are not “who over- and under-performs” in general, but the ones that would stay off the line after conditioning on skills.

⚠ Two cautions before the lists below. First, “grew about as fast as knowledge capital predicts” is a statement about growth conditional on initial income, while “income above what skills predict” is a statement about the level of GDP per person. They are different questions and a country can be off one line and on the other. Second, calling a country an outlier is an empirical claim that requires a stated outcome, period, sample, model and a reproducible residual calculation. None of that has been done here, so what follows is a guide to mechanisms.

Two patterns to look for

A guide to mechanisms · not a fitted regression

Skills matter. So does the route from skills to income.

These are explanations to investigate when educational performance and economic outcomes diverge. They are not a ranking of countries.

Skills put to use

Learning can support production

People can apply their skills in firms and markets.

A route from skills to economic gains

Skills face barriers

Potential may go unrealized

Weak institutions, limited market access, or migration can interrupt that route.

A possible explanation for lower output

Income has other sources

Resources can lift income

Oil, gas, or other resource rents add income beyond what test scores measure.

A possible explanation for higher income

The examples in this article are illustrative. No residual analysis has been reproduced, so this figure does not certify any named country as an outlier.

What to take away A genuine outlier chart needs a defined outcome, comparable test years, and a fitted model. GDP per person and GDP growth answer different questions.

Sources & context: Hanushek & Woessmann, The Knowledge Capital of Nations

Pattern 1 — mechanisms that can put income above what measured skills would predict. The examples are illustrative candidates, not classified outliers.

Type	Examples	Mechanism
Resource rents	Gulf states (Qatar, Kuwait, Saudi Arabia, UAE)	Oil and gas income is unrelated to the schooling system. Several score poorly on PISA relative to income.
Financial and legal entrepôts	Luxembourg, Switzerland, Singapore (partly)	Institutions and location capture returns beyond domestic human capital. Singapore also genuinely tops the tests.
Historical capital stock	Italy, parts of southern Europe	Accumulated wealth and industrial base sustain income as measured skills soften

Pattern 2 — mechanisms that can hold income below what measured skills would predict. Same caveat: candidates, not classifications. Note that several of these entries lean on schooling or literacy (“high literacy and universities”, “formal education inheritance”) rather than measured cognitive skills — which is the very substitution Hanushek and Woessmann argue against, and a reason to treat them as hypotheses to test rather than findings.

Type	Examples	Mechanism
Stranded human capital	Armenia, Georgia, Moldova	Educated populations, geographically or politically cut off from markets
Post-Soviet skills mismatch	Ukraine, Kyrgyzstan	Strong formal education inheritance, institutions that don’t convert it
Institutional failure	Argentina is the canonical case	High literacy and universities, a century of relative decline
Brain drain	Much of the Caribbean, parts of the Balkans	The country pays to build the skills; another country gets the output

Armenia, which is where the question came from

Cowen asks whether Armenia can work, given Russia. Acemoglu — who is Armenian — gives a blunt answer: “It has disappointed. Armenia has really disappointed. It has underperformed economically.” His explanation is almost entirely geographic and geopolitical, not educational:

“It’s a landlocked country. It cannot export anything because, again, transport is not a possibility. It has to find a way of using its talent.”

The data complicate the story in an interesting way:

Indicator	Value
GDP per capita	~$8,900 (2025 est.), upper-middle income
TIMSS mathematics (grade 4)	Among the lowest in its region, though improving since 2011
PISA	First participation 2025 — no comparable historical scores
World Bank Human Capital Index	A child born today will be 58% as productive as with full health and education
Expected years of schooling	11.3 — falling to 8.0 when adjusted for learning quality

Sources: World Bank Armenia learning analysis · TIMSS 2023 Armenia · World Bank on Armenian education and growth (archived copy)

This is the nuance worth carrying. Both Cowen and Acemoglu treat Armenian human capital as a given — “the people are so smart,” “the people are well educated.” That is the Soviet inheritance talking: Armenia was the USSR’s engineering and technical hub, and the reputation is real. But the measured learning of children in school today is weak, and the 11.3 → 8.0 adjustment says most of the gap is quality, not access.

So Armenia may be a smaller outlier than it looks. Part of the underperformance is stranded geography, as Acemoglu says. Part of it is that the knowledge capital is a legacy stock that is not being replenished — which is exactly what the Hanushek–Woessmann framework would predict from those test scores. Neither man raises this, and it slightly undercuts the “smart people, bad geography” story they agree on.

Working notes

The interesting tension, and I’d want your read on it. Hanushek and Woessmann say cognitive skills drive growth. Acemoglu’s own published work says institutions drive growth and human capital is substantially downstream of institutions. These are rival explanations of the same correlation, and Acemoglu is a principal in the fight. In this interview he answers the Armenia question in pure institutions-and-geography terms without mentioning schooling quality at all — which is exactly what you’d predict from his research program, and it’s a nice illustration of how a scholar’s framework shows up in an off-the-cuff answer. That observation is mine and is worth a page of its own in draft 2.

⚠ What is not properly sourced here. The over/under-performer tables are constructed from the general shape of this literature, not lifted from a specific published residual analysis. They are directionally right and individually defensible, but there is no single table in Hanushek–Woessmann that looks like mine. If you want this to be rigorous rather than orienting, the move is to reproduce their growth regression and rank the residuals — which is genuinely doable with public PISA and Penn World Table data, and would give real answers instead of archetypes.

Also unverified: the specific Gulf-state PISA-versus-income claim, and the Argentina characterization, are conventional wisdom in this literature rather than things I checked today.

What draft 2 needs: a scatter plot — test score on x, GDP per capita or growth on y, with the residual outliers labeled. That is the picture the question is really asking for, and it’s buildable from public data. Armenia should be plotted on it.

Checked against the book — and the tension above is confirmed by absence. What Happened to Liberal Democracy? contains no PISA, no test-score data, no growth regression on cognitive skills, and no engagement with Hanushek and Woessmann. Armenia appears once, in an unrelated aside about inoculation. So the observation this page makes — that Acemoglu answers a schooling-quality question in pure institutions-and-geography terms — is not a quirk of an off-the-cuff interview answer. It is what his book does too: education enters Chapter 1 as a public service failing to convert spending into outcomes (see NYC vs London - School Spending) and never as a driver of growth. The rival-explanations framing stands, and the page can now say so about his stated position rather than inferring it from a research programme.

Checked against the audiobook edition (Penguin Random House Audio, narrated by John Lee), machine-transcribed; references are by chapter. A negative finding from a transcript is weaker than one from an index, though a literature engaged nowhere in twelve hours is not one being quietly relied on.
