Double Deflation
From Open Risk Manual
Definition
Double Deflation refers to a two-step process by which Intermediate Input, Final Demand, and Total Output valued at current prices in the accounting period are “deflated” by using commodity price indices (CPI) and subsequently deriving a value added price index that enforces the fundamental identity that the value of total outputs must always be equal to the value of total inputs. [1]
Issues and Challenges
If deflators for intermediate inputs and/or gross output are not perfect, however, deflated value added figures will be distorted.
