We consider an open Leontief (input-output) model such that the input-output matrix can be selected by a decision maker from a given finite set A of nonnegative matrices fulfilling the "product property." We present algorithmic procedures for testing if the set A contains feasible solutions ...
Leontief输入-输出分析模型说明书 Package‘leontief’October13,2022 Type Package Title Input-Output Analysis Version0.2 Date2020-09-01 Description An implementation of the Input-Output model developed by Wassily Leontief that represents the interdependencies between different sectors of a national economy or...
Matrix A is called input-output matrix or consumption matrix. A consumption matrix shows the quantity of inputs needed to produce one unit of a good. The rows of the matrix represent the p 1 = m 11 p 1 + m 12 p 2 +… + m 1n p n +d 1 p 2 = m 21 p 1 + m...
Matrix A is showing relationships of inputs consumed per unit of sector output. External demand for the economy is d = [ ] P = (I – A)-1d I – A = [ ] To find out (I – A)-1, first we need to know if inverse of (I-A) exists. In 3x3 matrix, B = [ ]. There ...

The student will be able to formulate and solve the three-industry model of input-output analysis. Leontief Input-Output Analysis In this section, we will study an important economic application of matrix inverses and matrix multiplication. This branch of applied mathematics is called input-output ...
