In ignaciomsarmiento/ioanalysis: Input-Output Analysis

Description

Computes the first order field of Influence

Usage

influence(mip,X, col,row, write.xlsx=FALSE, name="Field_of_Influence.xlsx")

Arguments

mip	Matrix. Input output matrix
X	Vector. Input in each column
col	Numeric. Column where the change is occurring
row	Numeric. Row where the change is occurring
write.xlsx	Logical. If TRUE writes an excel file
name	String. Name of the excel file

Details

The Field of influence assesses the changes in the Leontief inverse matrix resulting from the change in one or more direct input coefficients in the inverse Leontief matrix.

The first order field of influence deals with a single change in one elements of the coefficient matrix.

Value

Returns a matrix.
