Macroeconomic problems and approach of the parametric control theory

The paper presents the results of the approach to the solution of some macroeconomic problems of the regions (economic growth, reduction of regional disproportions, reduction of trade deficits and growth of the agricultural, forestry and fishery sector outputs) based on the developed Model and the approach of the parametric control theory. The developed Model is a global multi-country dynamic computable general equilibrium model (CGE model) which was built based on the known static CGE model Globe 1. The assessment of the fulfillment of the conditions for transferring the results of computational experiments based on the Model was carried out both by the approach of the parametric control theory and by other known methods. The problems of dynamic optimization that allow solving these macroeconomic problems at the level of individual countries, the economic union and the world economy were solved based on the Model, with methods of the parametric control theory. The greater benefit from joint concerted actions to solve the problems under consideration in comparison with the corresponding solutions of such problems at the level of individual regions (countries) is corroborated.
