Psychic Stock: An Independent Variable Category of Inventory

The supply‐side or demand‐servicing functions of inventory are well‐known in the inventory,logistics, and retailing literature.

This article introduces the concept of psychic stock, defined as retail display inventory for stimulating demand. Psychic stock is a minimum inventory level, which is modelled by a partitioning of psychic, cycle, and safety stock.
