rsp: Regional Supply Percentage Updating

In ioanalysis: Input Output Analysis

Description

rsp uses the RSP technique to update the matrix of technical input coefficients A from an InputOutput object created from as.inputoutput. The function calls upon import.total and export.total to calculate the imports and exports.

Usage

rsp(io)

Arguments

io	An InputOutput class object from as.inputoutput

Details

The new matrix of technical coefficients is calculated as follows:

A_{new} = \hat{p} A

where \hat{p} is a diagonal matrix with each diagonal componenet calculated as

p_i = \frac{X_i - E_i}{X_i - E_i + M_i}

Value

Anew	The updated matrix of technical input coefficients
