Secondhand Depreciation Illustration
Canonical definition
The Secondhand Depreciation Illustration is the diagnostic natural experiment in which the price differential between a new and a secondhand unit of a materially identical Object isolates the non-transferable components of the Mimetic Premium (PM-visible acquired from primary-market theatre, PM-ownership of first-hand acquisition, and PM-portfolio signalling from visible primary-market purchase), by holding PA (A-function) and PI (I-enablement) constant across the two transactions and attributing the residual price collapse to the evaporation of non-transferable PM channels upon transfer from original purchaser to secondhand buyer.
Explanation
When a factory-sealed or materially identical Object is resold shortly after primary-market acquisition at a substantially lower price (typical ranges, 10 to 60 per cent depending on Object class), standard economic accounts must attribute the gap to information asymmetry, warranty loss, or depreciation from use. The Secondhand Depreciation Illustration exposes the inadequacy of these accounts when condition is stipulated as identical. The A-Functional Price of the Object (its capacity to satisfy the A-need the category serves, carrying items, providing transport, telling time) is unchanged. The I-Adequate Price of the Object (its I-enablement, whatever craft, interpretation, or process participation it supports) is unchanged. What has changed is the PM component, and specifically those PM channels that do not survive transfer, the "I bought this new from the flagship" signal, the primary-acquisition theatre, the receipt that authenticates the first-hand purchase, the visible first-hand acquisition within a reference group. The residual PM that persists in the secondhand price (brand recognition, model identification, visible logo) is PM-visible that is transferable because it operates through the Object itself rather than through the transaction that produced it. The diagnostic power of the illustration lies in its isolation of PM empirically, without requiring counterfactual estimation from rental yields, hedonic regression, or visibility manipulation, which is why it complements but does not replace the Housing PM Decomposition. The inverse case (collectibles, limited editions, discontinued models that appreciate on the secondhand market) confirms rather than refutes the account, secondhand appreciation occurs precisely when secondhand transaction itself carries PM (scarcity signalling, connoisseurship signalling) exceeding the PM lost in transfer. The direction of price movement tracks the direction of net PM transfer, as the PM decomposition predicts.
