Baumol in the scriptorium

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Cost disease — the modern observation that string quartets and haircuts get relatively dearer because their productivity cannot rise while wages elsewhere do — is usually thought a phenomenon of industrial economies. Join it to the copyist: hand-copying was the archetypal stagnant sector for two thousand years, so wherever cloth, metal, and building grew more productive across the medieval centuries, books should have grown relatively dearer against manufactured goods even while tracking wages, a slow-motion cost disease ending only with the press. Stationers could not speed the hand, so they could only ride the wage. If this holds, the common assumption that pre-modern relative prices were roughly static breaks, and the book's rising relative price becomes an index of everyone else's progress.

Prediction clause (verbatim)

Primary clause (carries the verdict): the price of a comparable plain book relative to a fixed bundle of manufactured goods (an ell of cloth, a pound of nails, a pound of candles) rises by at least 25% between the 12th and mid-15th centuries in at least two independent regional series, while the same book's price in unskilled day-wages stays within plus-or-minus 20%. Secondary clause: an ancient anchor point from Roman Egypt sits below the medieval relative-price trend line.

Kill-dataset (verbatim)

SDBM price series with published commodity price deflators, anchored by papyri.info (in-house) book and commodity prices for the ancient comparison; the kill is a statistical trend test.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

Baumol himself names handicrafts/custom clothing as stagnant sectors and hand-copying is the archetypal one, but no one has explicitly fitted the cost-disease prediction to manuscripts—book price rising >=25% against a manufactured-goods bundle from the 12th to mid-15th c. while flat in day-wages.
