Cycles in the two-sex problem:  an investigation of a nonlinear demographic model.
"A fundamental shortcoming of classic stable population theory is its failure to handle populations differentiated by sex.  The classic theory is linear while the two-sex problem is inherently nonlinear.  Previous two-sex investigations have focused on equilibrium conditions rather than dynamics, and ignored competition between age groups for marriage partners. This study makes a start at analyzing dynamics and models that incorporate competition, which can play an important role in any realistic marriage model and can turn a model with a stable equilibrium sex ratio into one with a cycling equilibrium."  This is a revised version of a paper originally presented at the 1990 Annual Meeting of the Population Association of America. (SUMMARY IN FRE)
