mpm: Multiplier Product Matrix

In jjpwade/ioanalysis: Input-Output Analysis

Description

mpm calculates the multiplier product matrix using an InputOutput object calculated from as.inputoutput. The method is described below.

Usage

mpm(io)

Arguments

io	An InputOutput class object from as.inputoutput

Details

Let L be the Leontief inverse. Then the multiplier product matrix M is calculated as follows:

M = 1/v L_c L_r

where v = t(1) L 1 such that 1 is a column matrix of ones, L_c = L 1 is a column matrix of row sums, and L_r = t(1) L is a row matrix of column sums.

Value

M	Multiplier Product Matrix
