摘要

We consider the macroeconomic model proposed by T. Puu, which describes fluctuations in gross income in a given region. Under a special combination of savings and investment rates, income deviations occur only for a finite period of time, after which the income returns to a stationary state. In mathematical physics, this effect is called the Huygens effect (principle). Results of the study of the model by statistical methods allow one to speak about the plausibility of the hypothesis about the presence of the Huygens effect in certain periods of the history of the Russian economy. The question on the structure of the set of stationary zeros of nontrivial solutions of a stationary equation is considered.
