Primes¶
- Adverse Selection
- The construct was introduced in its modern form by Akerlof in "The Market for 'Lemons'" — which together with the subsequent work of Spence
This sourcePorts the information-asymmetry pattern into the labor market, showing costly signals (education) can establish a separating equilibrium when employers cannot observe productivity — and that such signaling can be wasteful even when it works; supports the prime's job-market-signaling and 'signaling is wasteful' claims.

- Asymmetry
- Recognizing the shared structure lets a reader who knows one instance read a problem in a far substrate and immediately ask the useful questions — which side is privileged, in what currency, and what would re-balance the relation, a cross-substrate transfer Spence (1973) demonstrated when he ported the information-asymmetry pattern from used-car markets into the labor-market signaling problem.
This sourcePorts the information-asymmetry pattern from product markets into the labor market, showing that costly signals (education) can establish separating equilibria when employers cannot directly observe worker productivity — a canonical cross-substrate transfer of the asymmetry structure.

The only text held for Spence (1973) is the publisher's table of contents, which names hiring under uncertainty and applicant signaling but says nothing about used-car markets or a cross-substrate port.
“2. Hiring as investment under uncertainty, 356. — 3. Applicant signaling, 358.”

- Certification
- A degree is a certification; wearing an expensive suit is a signal.
This sourceDistinguishes a costly self-revealing signal (e.g., education as a signal) from third-party-routed attestation, grounding the certification-versus-signaling contrast.
- A degree is a certification; wearing an expensive suit is a signal.
- Information Asymmetry
- Once a situation is recognized as information asymmetry, the standard responses become candidate interventions regardless of domain: the informed party can signal (incur a cost that is only worth bearing if the hidden fact is favorable), the uninformed party can screen (offer a menu that induces self-sorting), a third party can certify or audit, or the informed party can bond (post something forfeit if the hidden fact proves unfavorable).

Spence's TOC shows the paper treats 'Applicant signaling' — the informed party's costly signal — but gives no text for the cost condition or the other three responses.
“3. Applicant signaling, 358.”

- Relevance Substitution
- It is distinct from statistical confounding (a spurious association from an unmeasured variable) and from signalling (conveying private information through costly action, where relevance substitution is receiving a signal that does not carry the information it appears to).
This sourceFoundational model of signaling, where a costly action conveys private information — contrasted with receiving a non-informative substituted signal.

- Revealed Preference
- It connects to the cost-of-signal logic shared with signaling theory: signals the sender pays for carry information that cheap talk cannot, and revealed preference is the consumer-theory instance of an insight that recurs in biology and game theory.
This sourceEstablishes the cost-of-signal logic that costly acts carry information cheap talk cannot — the kin insight to revealed preference.

- Signal Devaluation
- Review-star and engagement inflation. Platform star ratings drift toward the top of the scale, and follower or like counts drift upward, with recipients adapting by reading ratios and review text rather than scalar scores. Certification and biological display. Consumer certifications proliferate and weaken as low-bar bodies compete for issuance, while runaway sexual selection inflates costly displays — a structural, not merely metaphorical, parallel.
This sourceOriginates the separating-equilibrium theory of costly signaling whose breakdown under elastic supply is signal devaluation; supplies the levers (cost gradient, supply constraint).

Domain-specific¶
- Bayesian Persuasion
- Bayesian persuasion turns on a binding signal structure; remove the commitment and the whole result collapses to cheap talk. Not Spencean signalling. In signalling, the sender's own type is the private information, revealed through a costly action
This sourceThe founding signalling model, in which a job applicant's unobserved productivity is conveyed by a costly signal whose cost falls with productivity.

- Cheap Talk
- In Spence-style signaling, a message is credible because producing it imposes a cost that is differentially lower for higher-quality senders, making mimicry unprofitable

Mechanisms¶
- Anchor Customer or Anchor Tenant Strategy
- Its strength is leverage from a single well-chosen commitment: a credible anchor's visible adoption lowers the perceived risk for everyone who follows, because their willingness to commit signals private information the crowd can't see for itself
This sourceModels a visible commitment as a signal that conveys information unavailable to the observing side.

- Costly Demonstration
- This is the classic costly-signaling logic — a signal is separating only when it is far cheaper for the high type to produce than for the low type.
This sourceModels separating job-market signals through type-dependent signaling costs, with education less costly for higher-productivity workers than for lower-productivity workers.
- This is the classic costly-signaling logic — a signal is separating only when it is far cheaper for the high type to produce than for the low type.
- Costly Signal Requirement
- The discipline that keeps it honest is checking that the signal still separates types and still tracks what you care about, and retiring it when either fails.
This sourceModels signals that separate hidden types by remaining informative about an attribute the receiver values.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 7 of 20 citations: 1 supported, 6 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
