Input-Output Coefficient
From Open Risk Manual
Definition
Input-Output Coefficient (also technical coefficient) is any of the numerical elements of a symmetric Input-Output Matrix.
Interpretation
The input coefficients can be interpreted as the percentage share (%) of costs for intermediate inputs (goods and services) and primary inputs in Total Output (production value).[1]
Formula
The input-output coefficients, are calculated by dividing each value in the IO table by the corresponding column total (i.e., the production value).
where
- are the input coefficients for intermediate inputs,
- are the input coefficients for other primary inputs,
- is the flow of commodity i to sector j (transaction bloc of the IO table),
- is the flow of Primary Input i to sector j (Value Added bloc of the IO table)
- is the output of sector j (production value).
