Abstract:
The main aim of the study is to analyze the procedure for constructing differential equations used to model macroeconomic processes. The correctness of the model of economic growth in differential form is investigated. The inadequacy of the exponential growth of the economy is established. An alternative result is obtained in the form of a hyperbolic growth of significant economic indicators. A discrepancy between the proportional growth of capital and income is revealed. Considerations are put forward to identify the moment of occurrence of crisis phenomena. Corresponding adjustments to economic growth models are made. An approach to the use of balance equations for modeling economic dynamics for the purpose of obtaining prediction estimates is generalized.

Keywords: international trade, bifurcation, chaos, balance, resource, dynamics, stability, equilibrium.
