Definition
Input-Output Coefficient (also technical coefficient) is any of the numerical elements of an Input-Output Matrix. 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).
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).
