Modelling and Identification of Macroeconomic System Dynamic Interindustry Balance
Languages of publication
The article describes the constructing process of interindustry balance model of macroeconomic system. The method of determining the oscillation period of macroeconomic dynamics was proposed. It also sets interrelations between number of significant harmonics and number of sectors. This approach is based on the decomposition of trajectories of outputs movement and non-productive consumption of certain sectors and economy as a whole. This allows receiving of qualitative simulation and predictive characteristics for macroeconomic development. Non-productive consumption was calculated using feedback. The unknown matrices of Leontief's model were evaluated based on inequality constraints on the parameters. Approbation of the model was carried out on example of the French economy. Analysis of the input data and the separation of macroeconomic system on sectors were made. The parametric identification of trajectories outputs and non-productive consumption were conducted.
