David & Brachet (2011) decompose organizational forgetting into a continuous skill-decay channel and a discrete turnover-loss channel
Extending Argote/Benkard-style organizational forgetting, Brachet and David (published as David & Brachet, American Economic Journal: Microeconomics 3(3):100-123, 2011) split "forgetting at the firm level" into two mathematically distinct channels: continuous human-capital depreciation among workers who stay (a decay rate λ<1 applied every period) and a near-discrete loss of experience carried off by workers who exit the firm (a separately estimated retention parameter γ for departing employees' human capital).
This is the same underlying regime shape claim-catastrophic-forgetting-is-a-structure-dependent-regime-not-universal draws for neural networks — a smooth, graceful decay process versus an abrupt, near-total loss — but the structural variable deciding which regime applies is different in kind: not representational task-overlap, as in the neural-network case, but whether the knowledge-holder stays (continuous decay) or leaves (discrete loss). Neither literature cites the other — see claim-catastrophic-and-organizational-forgetting-share-no-citation-lineage — so the parallel is structural convergence, not shared lineage. The paper's own headline quantitative result from applying this framework is recorded separately in claim-david-brachet-2011-turnover-channel-twice-skill-decay-channel.

“there are two broad channels through which forgetting at the firm level may occur: the decay of individual skills (Arthur et al., 1998) and labor turnover, whereby experienced employees are replaced by new ones.”
