title: Self-generated fertility waves in a non-linear continuous overlapping generations model.
abstract: In this paper, Samuelson's simplified version of the Easterlin theory is extended to a continuous-time model with 3 age groups.  This approach enables one to apply the qualitative theory of nonlinear differential equations to show the existence of Easterlin-type cycles.  In contrast to the discrete time model we obtain information about the period length of the cycle.
