Balance, optimality and economic equilibrium in the open production systems
In mathematical modeling of economic equilibrium distinction between the gross output of production and its commodity component is usually ignored that isn't absolutely correct. It is shown that use of Leontyev's model when forming balance of Errou-Debra type leads to the products market where economic equilibrium exists if the Leontyev's matrix is productive, and a vector of the prices of all the types of production is included in it as the semipositive. It is shown also that monetary expenses on that part of products on which there is a consumer demand in equilibrium will always be positive (in the balance prices).
