title: [Post-transitional cycles and prey-predator models].
abstract: "This paper investigates the logical consistency of the mathematical models used in the analysis of fertility fluctuations since the end of [the] demographic transition.  Two main families of models may be distinguished: those related to demographic 'cinematics', including the well known Easterlin model; and those related to the 'dynamics' of the reproduction system, among which Volterra's prey-predator model takes a particular place.  The possibilities of operationalizing the latter model are also discussed."  (SUMMARY IN ENG AND SPA)
