Price

A buyer reads the value of a coupling at her site, weighted by what she expects it to produce. A seller reads it at his. Where the readings overlap, the exchange runs.

A market is where many such readings pool. The price is where the pooled bids and the pooled asks meet.

The price is not the truth about value. It is the resolution of the readings actually present at the moment of clearing.

It carries what those readings carry. It does not carry what they leave out — costs nobody bid for, information one side had and the other did not, bargaining positions the structure had already tilted.

So the structure neither endorses nor refuses market pricing. It reads each market at the quality of its field. A rich field gives a price the structure can use. A compromised field gives a price the structure has reason to correct.

Administered, capped, internal, monopoly, algorithmic prices — all are constrained field resolutions. The field was narrowed before the bids met. The question is the same. What is the quality of the field that produced this number?

Nobody has to be rational for this to hold. The market reports the readings present. It does not clean them.
