Economics of machine intelligence

Which located texts, from 1952 to 2026, state, contest or bear on propositions about the economics of machine intelligence? Three strands are recorded. The first is the debate over whether machine intelligence could make economic growth explosive. The second is how mainstream economics treated automation, computers and AI. The third is how economists took up recursive self-improvement, superintelligence and existential risk from AI, ideas mostly discussed outside economics. For each proposition, which text by an economist is the earliest located, and which text outside that group?

Each proposition has one criterion. It is phrased generically and attributed to no one. A text that meets the criterion articulates the proposition. A text that disputes it, or a premise it depends on, contests it, and the record says whether the passage gives a reason against a premise or states the contrary only. A text that comes close bears on it, and its record names what is missing. A result from a formal model is shown with the conditions under which the model derives it. Each text carries a tier: tier 1 for scholarly work by economists and for the core economics journals and working-paper series, tier 2 for other texts. Texts are listed in date order. The page records what texts say and when. It does not assess whether an argument or a model is right.

A machine selected and arranged these records. No human review of the selection or framing is recorded.

How to read a record
Articulates
A passage meets the proposition’s criterion.
Contests
A passage disputes the proposition or a premise it depends on.
Bears on
A passage comes close without meeting the criterion; the record names what is missing.
Earliest located
The earliest articulation the searches found, dated by its wording. It is not a claim that no earlier text exists. The earliest located text that contests a proposition is chosen by the same rule.
Tier 1, tier 2
Tier 1: Scholarly work by economists in any venue, including their essays in magazines, and any text in a core economics venue, whoever wrote it. An economist has an economics appointment, degree, address or affiliation shown in or near the text, or an established record as an economist when the text was written. The core venues are the five leading general economics journals, the Journal of Economic Perspectives, the Journal of Economic Literature, AER Papers and Proceedings, NBER working papers and the NBER Economics of AI volume, and Kansantaloudellinen aikakauskirja for the Finnish texts. Tier 2: Texts by non-economists, whatever the venue, and short-form commentary even by economists: blog comments, forum replies, and magazine or online debates, unless a turn is itself a substantive scholarly argument. Earliest located is named within tier 1, and the earliest located tier-2 text separately. A tier is not a ranking of quality.
Earliest located use of the name
The earliest located text that uses the proposition’s usual name. A title can carry the name without stating the proposition.
Conditions
The model assumptions or stated conditions under which a passage holds. A conditional result is not a forecast.
Model scenario
A case of a formal model, under its conditions, that meets the criterion. It is not the author’s own claim, and it is shown only with its context.
Estimate
An estimate as the text states it, with its holder, horizon and the text’s own definition. Estimates from different texts are not converted or combined.
Engages a premise, states the contrary
A contesting passage engages a premise when its paragraph, message or dialogue turn gives a reason against it. Otherwise it states the contrary conclusion only.
Shown only with its context
A passage that would mislead on its own, such as an earlier view without the later text that rejects it. The evidence inspector shows it only together with the context it needs.
Dates
The first date is the one the work is dated by. “Wording attested” gives the date from which the quoted wording is known, when it survives only in a later copy. “Claimed” gives an earlier talk, draft or presentation that does not date the wording.
Register: the kind of text
Fiction, satire, a dream frame or a relay of another author is labelled. A passage in fiction records what the work says, not its author’s view. Unlabelled records are nonfiction.
Limits of this page
  • “Earliest located” means the earliest text found by the searches described under “How we searched”, by economists unless the page says tier 2. It is not a claim that no earlier text exists.
  • A record documents what a text says. It is not evidence that the proposition is true or that a model is right, and no record links one text to another.
  • A tier records who wrote a text and in which form, judged when it was written. It is not a ranking of quality.
  • A model result holds only under its recorded conditions. An estimate is its author’s, under the author’s definition and horizon, and estimates from different texts are not comparable without them.
  • Each record carries the date its work is dated by. Where the quoted wording is known only from a later copy or revision, the date from which it is attested is shown, and that date decides which text is earliest located.
  • A passage that would mislead on its own is marked “shown only with its context” and is never shown without that context.
  • Codes such as M05-20 in qualifications refer to the passages of the research packs the records come from.
  • A machine selected and classified these records, and machine checks from two model families re-examined them. No person has reviewed them.

G · The explosive-growth debate

Whether machine intelligence could make growth far faster than historical rates, the constraints argued against it, the evidence offered on both sides, and each text’s own estimate. Thirteen texts from 1994 to 2024.

G01 Machine substitution for labour produces explosive growth

Criterion. The text states that if machines (AI systems or emulated minds) can substitute for human labour across all or nearly all tasks, so that labour can be produced like capital, the growth rate of output rises far above historical rates (by roughly an order of magnitude or more) or keeps rising. The conditions under which the text derives this are part of the record.

  • Erdil and Besiroglu’s review (2023), headlined as the earliest located tier-2 text. Re-tiered as tier 1 after the re-checks of 2026-10-25: Besiroglu held an economics degree before the text. Davidson’s report (2021), whose toy scenario of AI robots substituting for all human labour meets the criterion, is now the tier-2 earliest. Recorded 2026-10-25.

G02 Automated research produces accelerating growth

Criterion. The text states that if machines substitute for, or improve, the producers of ideas (researchers, inventors, engineers), feedback from output to research effort makes growth accelerate: super-exponential growth, growth rates rising without bound, or a finite-time singularity. The conditions under which the text derives this are part of the record.

  • Hanson’s comment on Vinge (1998), headlined as the earliest located text that contests it before texts were sorted into tiers. Short-form commentary is tier 2 under the rule of 2026-10-11, so it is now the tier-2 earliest. Aghion, Jones and Jones (2017) is the earliest located tier-1 text that contests it. Recorded 2026-10-11.

G03 Long-run history suggests a further acceleration

Criterion. The text infers from the long-run history of world output or population (hyperbolic or super-exponential growth, or a sequence of ever faster growth modes) that a future transition to much faster growth is plausible or expected.

  • Hanson’s undated “Economic Growth Given Machine Intelligence” (attested 2000-08-19), headlined as earliest located from 2026-10-10. Earlier text found by the re-checks of 2026-10-25: Hanson’s “Is a Singularity Just Around the Corner?” (June 1998, attested 1999-01-28) makes the inference itself; the 2000 paper relays his own 1998 projection. Recorded 2026-10-25.
  • Hanson’s “Long-Term Growth As A Sequence of Exponential Modes” (2000), headlined as earliest located in the first pass. Earlier text found by the audit: Hanson’s undated “Economic Growth Given Machine Intelligence”, attested 2000-08-19. Recorded 2026-10-10.
  • The Asterisk debate (2023), headlined as the earliest located text that contests it in the first pass. Reclassified as bearing on it after the cross-family check: the same turn grants that past acceleration is a reason to think it could happen again. Recorded 2026-10-10.

G04 Essential unautomated tasks bottleneck growth

Criterion. The text states that growth is constrained because essential tasks or inputs remain unautomated or unimproved, or are automated only slowly, so that automating many but not all tasks, or automating them gradually, does not by itself produce explosive growth (Baumol's cost disease; an elasticity of substitution below one between tasks or between information and other inputs). Reasons why automation stays incomplete or slow (technical difficulty, physical-world tasks, training data, regulation of AI training or deployment, slow adoption) belong here.

G05 Other constraints prevent explosive growth

Criterion. The text states that constraints that would still bind if machines performed all or nearly all tasks (physical laws or limits, natural resources and energy, the time that natural processes and experiments take, regulation of activities other than AI training and deployment, or demand for human-provided goods) can prevent or quickly end explosive growth.

G06 Current data show no approach to explosive growth

Criterion. The text states, on the basis of current or recent economic data, that the economy shows no sign yet of approaching a growth singularity or explosive growth.

  • Nordhaus (2015), headlined as earliest located in the first pass. Reclassified as bearing on it after the cross-family check: he reports two positive tests of seven and concludes that the singularity is not near, which is not “no sign yet”. No tier-1 text now articulates G06. Recorded 2026-10-10.

G07 Machine substitution drives wages down

Criterion. The text states that once machines substitute for human labour at falling cost, the market wage of human labour falls (towards the cost of machine labour, or below subsistence), even while total output or wealth rises.

  • Hanson’s “If Uploads Come First” (1994), headlined as the earliest located tier-1 text on 2026-10-11. An author’s standing is judged when the text was written (2026-10-12). In 1994 he held no economics degree or appointment, so the essay is tier 2 and is now the tier-2 earliest. Recorded 2026-10-12.

G08 AI’s near-term aggregate productivity effect is modest

Criterion. The text estimates or states that the effect of AI on aggregate productivity or GDP over roughly the next decade will be modest: a small effect on the level of output, not a change in the growth regime.

G09 Estimates of explosive growth within a stated horizon

Criterion. The text states its own estimate of whether or when explosive growth (as the text defines it) occurs in the actual future, with machine intelligence or automation among the stated drivers. Each record gives the holder, the estimate as stated (a number or words), the horizon, the text's definition and the conditions. Records are not converted to a common threshold, combined or ranked; a low estimate and a high estimate both articulate this proposition.

Earliest located, tier 1
Not assigned. Withheld on 2026-10-25 by maintainer decision. The earlier holder, Hanson’s “Economic Growth Given Machine Intelligence”, relays his separate 1998 projection. His “Long-Term Growth As A Sequence of Exponential Modes” (December 2000; first version September 1998) is an unchecked lead for the role.

M · Mainstream economics, automation and AI

How economists and economics venues treated automation, computers and AI from 1952 to 2024: as ordinary technical change, as the automation of tasks, as a general-purpose technology or as cheaper prediction, and what they said about wages, policy, measurement and the field itself. M06 is split into M06a and M06b. M09 states the prior that mainstream economics took up machine intelligence only recently; it is tested against the dated record, not confirmed.

M01 Computers and AI as ordinary technical change

Criterion. A tier-1 text dated before 2015 that discusses computers, automation or AI and analyses them with the tools used for technical change in general (factor-augmenting or skill-biased change, capital deepening), with no separate category for machine cognition.

Headlines replaced

  • Nordhaus (2015), headlined as earliest located. Reclassified as bearing on it after the cross-family check: his remark concerns the singularity in macroeconomics. The introduction to the NBER volume of 2019 is now earliest located. Recorded 2026-10-12.

E · Superintelligence and existential risk

Whether economists took up machine intelligence that improves itself, machine intelligence beyond human level in essentially all domains and existential risk from AI, how developers’ incentives bear on safety, and what texts say about the state of economics on these questions. Texts from 1998 to 2026, mostly NBER working papers, with Robin Hanson’s texts of 1998 to 2000 and posts from his 2008 debate with Eliezer Yudkowsky. E05 counts only explicit statements about the state of economics; economists’ engagement itself is recorded under E01 to E04.

E01 Machine intelligence improving itself accelerates its capability growth

Criterion. A text that states or models AI systems improving AI (their own capabilities, their successors' design, or AI research itself) so that capability growth accelerates. Accelerating output growth from automated idea production without AI improving AI is G02 and only bears on E01.

E02 Machine intelligence exceeding human cognition in essentially all domains

Criterion. A text that states or models the possibility of machine intelligence that surpasses humans across essentially all cognitive tasks (superintelligence, AGI beyond human level). Machines doing all economically valuable work more cheaply is M05 and bears on E02 only if cognitive superiority is stated.

E05 Economics’ engagement with superintelligence, AGI and the singularity

Criterion. A passage articulates E05 only if it explicitly says something about the state of economics on the topic: that it is new, neglected, speculative, now on the agenda of economics, or beyond economists' existing tools. Economists' engagement itself is recorded under E01–E04 and in the timeline (the dated record), not here. Machine intelligence that does human jobs is not counted as AGI for E05, as for E02. Maintainer decision of 2026-10-15.
