Compute output multipliers from a Leontief inverse matrix.
Arguments
- input_coefficient_matrix
A technology–coefficient matrix as returned by
input_coefficient_matrix_create().
Value
A one-row data.frame (or tibble) with:
The first column a label
"output_multipliers".Remaining columns the multipliers for each industry.
Details
The output multipliers are defined as the column sums of the Leontief inverse \((I - A)^{-1}\), where \(A\) is the input coefficient matrix. They measure the total direct and indirect output generated in each industry per unit increase in final demand.
