Claim

Under Coasean economics transaction costs determine firm size, so transaction costs falling to zero implies firm size falling toward zero.

Assessment

Supported

Score: 0.8336 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 3 counted

6 independent evidence lineages · review checks 3 of 4 · stability LOW

Main unresolved issue: 10 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:358d1424-ecb3-8826-b5a2-cbec9cf46c17

Not yet independently audited.Evidence points both ways.This assessment depends heavily on modeling choices.A quoted passage from python-advanced.quantecon.org was not found on the page when Galedra fetched it.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted support: A firm expands until an extra allocative measure costs more internally than by market contract. weight 0.918000 evidence

Strongest counted contradiction: Coase wrote that inventions bringing factors of production nearer together tend to increase firm size. weight 0.918000 evidence

Suppressed as dependent: The Nobel committee states that if transaction costs were zero, no firms would arise.; The excerpt says transaction costs determine firm size and that if transaction costs approach zero, firm size is pushed toward zero.; The passage says Coasean economics holds transaction costs determine firm size, so zero transaction costs push firm size toward zero.

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

prior 0.50 → log-odds 0.000000 + 1.611000 (the counted weights) = 1.611000 → probability 0.8336

Under neighbouring settings of the same model: 0.7554 to 0.8903, a spread of 0.1349. The result sits on a rounding boundary.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Directly supports transaction costs shaping firm scope; it does not explicitly state the zero-cost limiting case.
QuantEcon’s exposition supports the theoretical link between transaction costs and firm size, including the limiting case where firms have zero size in a zero-transaction-cost model; it is a stylized implication, not a prediction that all real-world firms will vanish.

The same speaker argues that walled-off frontier capability would drive firms larger, cutting against his own zero-size reasoning.
When transaction and organizational costs both fall, no simple prediction about firm size follows.

From The Myth of Diminishing Firms Read 2026-09-21 Relevance STRONG Steps 1 Counted

Cuts against the inference rather than the limit. Firm size is set by the ratio of transaction to organizational costs, and technology that lowers one generally lowers the other, so falling transaction costs do not imply falling firm size. Source is an opinion column in CACM by a computer scientist, not an economics journal article; weigh accordingly.
Coase wrote that inventions bringing factors of production nearer together tend to increase firm size.

Coase's own 1937 text going the other way: cost-reducing invention tends to increase firm size. Quoted from a review page rather than from Economica, whose publisher refused access, so the attribution to Coase rests on that page's accuracy.

Qualifications

QuantEcon’s exposition says Coasean firm size is determined by balancing market transaction costs against internal management costs, rather than by transaction costs alone; therefore lower transaction costs do not by themselves entail firm size falling to zero.

From Coase’s Theory of the Firm — Advanced Quantitative Economics with Python Read 2026-09-28 Relevance DIRECT Steps 0 Counted

This directly narrows the claim’s zero-limit inference while supporting its transaction-cost premise.
Coase’s original account makes firm size a marginal comparison between internal organizing costs and market costs, and also emphasizes rising internal organizing costs; it therefore qualifies a simple zero-market-cost implication.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
