Guy David and Tanguy Brachet (University of Pennsylvania), "On the Determinants of Organizational Forgetting" (MPRA Paper No. 21464, 2009 working paper; published as David, Guy and Tanguy Brachet, *American Economic Journal: Microeconomics* 3(3):100-123, 2011). Using a 1991-2005 panel of Mississippi ambulance companies and their paramedic workforce, the paper splits [[entity-organizational-forgetting|organizational forgetting]] into a continuous skill-decay channel and a discrete labor-turnover channel, finding turnover contributes roughly twice the forgetting that skill decay does. It had recurred across three claim-notes with no hub of its own before this session's bibliometric check made the paper itself, and its position in the citation graph, the subject of two more.

A direct, complete read of its 26-entry reference list and of the 60 papers that cite it (Semantic Scholar Graph API, both queried 2026-08-12) found zero contact with the ML catastrophic-forgetting literature in either direction — the strongest evidence in the vault for [[claim-catastrophic-and-organizational-forgetting-share-no-citation-lineage]], though confirmed only for this one founding pair, not the full six-paper comparison the question behind it names.
