About the problems of resonance and cyclicity in economic dynamics

This article is devoted to cyclical problems in economic dynamics. The imposition of cyclic waves is possible, both in the same and in different frequency characteristics. The total cyclic wave can both amplify and decrease. However, if the frequencies of the internal oscillations coincide with the frequencies of the external oscillations, a nonlinear increase in the amplitude of the total oscillations can be observed and can lead to resonance in the economic system. The article also explains the resonance problem using a conditional example. Under certain conditions the system can change the state trajectory. The work also substantiates an appeal to the methods of the theory of deterministic chaos, since it is impossible to describe the nonlinearity of turbulence and bifurcation using the methods of classical economic analysis. An analysis of the causes and consequences of the recent economic and financial crises showed that their suddenness, is primarily associated with outdated scientific approaches to forecasting socio-economic development...
