Capital accumulation, aspiration adjustment, and population growth:  limit cycles in an Easterlin-type model.
"One of the recent interesting hypotheses of population growth is due to Easterlin who suggests the possibility of self-generating fluctuations in birth numbers.  The present paper tries to answer the question whether feedback mechanisms produce persistent oscillations in population growth.  A system of two nonlinear differential equations for the per capita capital stock and the aspiration level is studied by a phase portrait analysis.  Using the Poincare-Bendixson theorem we derive sufficient conditions for the existence of a stable limit cycle." (SUMMARY IN FRE)
