Some Applications of Matrix Theory in Economics
The paper provides some applications of matrix theory in economics. In particular, when the industry is connected by production and consumption of different products, the number of planned gross product of industries, inter-industry delivery of products, and net products of industries is calculated. The task of finding the budgets of states, with the specified structural matrix of trade of these states and the sum of their budgets, is also being considered. In addition, the application of the concept of eigenvector and eigenvalue to find the ratio of state budgets to balance the trade of participating states is considered.
