Price Shares (sA, sI, sM)

Canonical definition

Price Shares (sA, sI, sM) are the fractions of a transaction price contributed by each component of the Price Decomposition: sA = P\<sub\>A\</sub\>/P\<sub\>total\</sub\>, sI = P\<sub\>I\</sub\>/P\<sub\>total\</sub\>, and sM = P\<sub\>M\</sub\>/P\<sub\>total\</sub\>, non-negative and summing to 1. They are the price-register analogue of the AIM Weights: where wA, wI, and wM partition the pull on a Decision Hub at the moment of choice, sA, sI, and sM partition the money in a transaction. The two triples are related but not equal: sM coincides with wM only where the source-specific utilities of the Object are equal, and the divergence between them is itself informative, since a good bought by Individuals of modest wM can still carry a large sM where its Mimetic utility dominates its A-function and I-enablement. sM is the natural object of M-targeted policy (the M-Tax base) and of any good-level or firm-level measurement of Mimetic Premium extraction, because it is defined on the observable transaction rather than on any Individual's Decision Hub.
