What are the specific statistical estimates behind Barnett & McKendrick (2004)'s hard-disk-drive Red Queen finding?

This capture is a direct follow-up to the vault's routed question question-verify-barnett-mckendrick-2004-disk-drive-hazard-estimates, which asks for the coefficients, hazard ratios, sample size, and years-of-data behind the finding already captured at the directional level in claim-barnett-mckendrick-2004-tested-red-queen-on-disk-drive-makers (large firms led the technology race but failed to become stronger competitors than small rivals, per Barnett & McKendrick's own abstract, Tier 1). That existing note is not duplicated here — see it directly.

Claim: The full text of Barnett & McKendrick (2004) was not reached this session; the specific statistical estimates remain unconfirmed

Every located route to William P. Barnett & David G. McKendrick, "Why Are Some Organizations More Competitive than Others? Evidence from a Changing Global Market," Administrative Science Quarterly 49(4):535–571 (2004), returned a paywall or an access error during direct, first-hand fetch attempts on 2026-07-28:

• Durham Research Online / Durham University's institutional repository (Worktribe platform) — both the abstract page (https://durham-repository.worktribe.com/output/1631157/) and the direct PDF (https://durham-repository.worktribe.com/preview/1631176/2516.pdf) returned HTTP 403 to both extract_pdf and direct fetch, despite this being the repository Semantic Scholar's metadata records as the paper's open-access, CC-BY-licensed copy.

• An r.jina.ai reader-proxy retry on the Durham PDF returned HTTP 401.

This is a first-hand, direct-observation record of access attempts (this researcher's own fetch results), so it clears its own floor as an uncontested, present-tense fact about access, not about the paper's content. It does not stand in for the paper: no coefficients, hazard ratios, model specification, sample size, or years-of-data were recovered. The routed question stays open and unresolved [unverified — could not confirm or deny after search] for its quantitative core. The directional finding (large firms lead technologically but do not gain relative competitive strength) remains the only part of this paper's content confirmed at Tier 1, and that was already established in claim-barnett-mckendrick-2004-tested-red-queen-on-disk-drive-makers from the authors' own abstract on the Stanford GSB faculty page.

Claim: Semantic Scholar's bibliographic record lists the paper as openly available via Durham Research Online under a CC-BY license, though the repository itself refused direct access this session

Querying the Semantic Scholar Graph API by DOI (https://api.semanticscholar.org/graph/v1/paper/DOI:10.2307/4131490 — this exact query URL returned live JSON content, confirmed resolving) returned title, year, and author metadata matching the known citation, plus an openAccessPdf field pointing to https://durham-repository.worktribe.com/output/1631157 with license "CC BY." This is a definitional/administrative claim about where the paper is catalogued as hosted, not a claim about the paper's statistical content, so it clears the floor at Tier 3–4 (aggregator metadata) for that limited purpose. It does not override the fact that the repository itself returned 403 to every fetch attempt this session — the CC-BY licensing claim and actual public reachability are two different things, and only the latter was tested directly.

Entity candidates

• David G. McKendrick — person — co-author of the 2004 ASQ paper and sole/lead author of at least two other hard-disk-drive-industry studies (2001 SMJ paper; From Silicon Valley to Singapore); no entity note currently exists for him despite his recurring role alongside entity-william-barnett.
• Glenn R. Carroll — person — co-author (with Barnett and McKendrick) on the related 1965–1998 hard-disk-drive-population working paper; organizational-ecology scholar, not yet in the vault.
• J. Richard Harrison — person — co-author on the same related working paper; not yet in the vault.
• Albert C. Y. Teo — person — co-author on the same related working paper; not yet in the vault.
• Note on the "foundational figure" blind spot: the figure this whole Red Queen line of work measures itself against is Leigh Van Valen, already present in the vault as an entity — flagged here explicitly so it isn't missed, though no new page action is needed since it already exists.
