ИСПОЛЬЗОВАНИЕ СРАВНЕНИЯ МОДЕЛЕЙ СОЛОУ И ХАРРОДА – ДОМАРА В СТРАТЕГИЧЕСКОМ МАКРОЭКОНОМИЧЕСКОМ ПЛАНИРОВАНИИ

Abstract

The validity of the basic economic identity is assumed, i.e. equality of income to the sum of consumption and investment. All quantities depend on continuous time. Income is understood both in its pure form and as gross domestic product, or national income. Consumption is also understood in different ways: both pure consumption and total consumption. First, we consider the Harrod – Domar macromodel with the time-dependent capital intensity of income growth. A new variable is introduced - the relative increase in income of the Cobb – Douglas production function and the balance equation for capital is considered. As a result, we obtain confirmation that the capital intensity of income growth in the Solow model can depend on time. It is shown that the balance equation for accumulated household savings also satisfies the basic economic identity and the capital intensity of income growth can depend on time. The interpenetration of these two macromodels can be used in strategic planning.
