The dynamics of two linearly coupled Goodwin oscillators
Анотація
In this paper the Puu model of the interaction of Goodwin’s business cycles for two regions is reconsidered. We investigated the effect of the accelerator coefficients and the Hicksian ’ceiling’ and ’floor’ parameters on the time dynamics of incomes for different values of marginal propensity to import. The cases when the periods of isolated Goodwin’s cycles are close, and when they differ approximately twice are considered. By perturbation theory we obtained the formulas for slowly varying amplitudes and phase difference of weakly nonlinear coupled Goodwin oscillations. The coupled oscillations of two Goodwin’s cycles with piecewise linear accelerators with only ’floor’ are considered.
