Macroeconomic indicators forecasting based on the matrix balancing method and its modifications
The matrix balancing method is used in the Republic of Belarus to predict the Input-Output table. The input parameter in this method is only the target value of GDP for the forecast year, and it is assumed that all elements of the considered matrices are positive. In practice, such assumption is not applied for matrices with a high level of detail of economic activities types. Various modifications of the MMB (algorithms b , 8 , j , y ) are proposed, which make possible removal the assumption and simplifying the computational process implemented the MMB. Based on the reporting inter-sectoral balances of the Republic of Belarus for 20032018 computational experiments were carried out, the results of experiments indicate the acceptable forecasting accuracy of the proposed algorithms and the possibility to use them within forecasts and programs design of the country's socio-economic development.
