ONE-HOSS SHAY

Statistics Directorate    
Definition:
A model of depreciation, in which the durable delivers the same services for each vintage: a chair is a chair, no matter what its age (until it falls to pieces and is scrapped). Also known as the light bulb model of depreciation.

Context:
A one-hoss shay is a colourful term taken from the poem, “The Deacon's Masterpiece”, by Oliver Wendell Holmes (in nineteenth century American dialect, a “one hoss shay” is a cart drawn by a single horse.) “Shay” is a corruption of the French “chaise” or “postchaise”.

The term is used to designate a capital asset that exhibits neither input decay nor output decay during its lifetime.
