Primes¶
- Adverse Selection
- .
This sourceFounding formalization of adverse selection: a seller-held quality fact unverifiable by buyers drives good products out of the market (the unraveling mechanism), with counteracting institutions (guarantees, brand names, reputation) showing the distortion is a pressure rather than a deterministic outcome — supports every Akerlof/lemons/unraveling citation in the prime.
Supported in partVerified against the publisher's abstract
Akerlof (1970) is the cited founding paper, and its title and contents page confirm a model built on automobiles plus counteracting institutions, but no text is held, so the lemons mechanism and the priority claim are unverified.
“II. The model with automobiles as an example, 489.”

- Arbitrage (Generalized)
- Asymmetry
- Akerlof (1970) showed that information asymmetry alone can collapse a market into adverse selection, demonstrating that the structural property has stark equilibrium consequences.

- Exchange
- Green-Beard Effect
- In institutional and professional trust, licensing badges, association seals, certifications, and fair-trade marks license a cooperative posture, with the marker's value protected by enforcement against false displayers.
This sourceIdentifies brand names, guarantees, and licensing/certification as counteracting institutions whose value depends on enforcement against false displayers of quality.

Confirms only that Akerlof 1970 contains a section on 'Counteracting institutions' (p. 499); we hold no prose showing he ties badged licensing or certification to cooperative posture or in-group cost.
“IV. Counteracting institutions, 499.”

- Gresham's Law
- Adverse selection is the nearest sibling rather than a parent or instance: Akerlof's used-car market also loses its better grade, but hidden quality forces its pooling price, whereas an external rule imposes Gresham's parity.
This sourceDerives the unraveling of a market under unobservable quality at a single price, generalizing the withdrawal-and-concentration structure to information-asymmetric markets; supplies the used-car worked example and the adverse-selection sibling relation.

Akerlof's paper has a section on 'Counteracting institutions' - the locus of guarantees and licensing-like devices - but the packet holds only its table of contents, which does not state that these remedies repair adverse selection.

- Information Asymmetry
- Information asymmetry is the structural condition in which the parties to an interaction hold unequal private knowledge relevant to that interaction — one side knows something material that the other cannot observe or verify without cost.
Supported in partVerified against the publisher's abstract
Akerlof (1970) is the founding formalization of a seller-held quality fact buyers cannot verify; the only text we hold is the article's table of contents, which states no definition of information asymmetry.
“I. Introduction, 488. — II. The model with automobiles as an example, 489. — III. Examples and applications, 492. — IV. Counteracting institutions, 499. — V. Conclusion, 500.”

Mechanisms¶
- Reputation and Verification System
- Its strength is that it lets a platform grow a side safely — converting quantity into quality-preserving quantity — and it directly counters adverse selection, the tendency for a market with hidden quality to fill up with the worst participants
This sourceShows how buyers' inability to distinguish hidden quality can drive higher-quality goods out and leave a lower-quality market pool.

- Seller Rating or Quality Grading
- An online marketplace faces a market-for-lemons problem: buyers cannot tell reliable sellers from unreliable ones before purchasing, so they won't pay a premium for quality they can't verify, good sellers can't distinguish themselves, and average quality erodes toward the bottom.
This sourceWhen buyers cannot verify individual quality, they price against average quality, weakening rewards for good sellers and allowing average quality to deteriorate.

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 4 of 12 citations: 4 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
