Definition
An Output-to-Output Multiplier indicates how total production will change as Final Demand is changed in any one sector of the economy. This output multiplier measures the amount of output generated by a $1 change in final demand for the output of the jth sector.[1]
Output multipliers are an example of the questions tackled by Input-Output Analysis.
Formula
The output multiplier for sector j is the sum of column j of the Leontief Inverse Matrix. If we represent the elements of the Leontief Inverse Matrix 
as 
, then the output multiplier is defined as the column sum:
