Abstract

We simulate the response of an age-structured population face to an abrupt increasing of fertility. Contrary to the exponential decay of original model, as reported by Coe and Mao, we have found that the relaxation to the equilibrium can be algebraic under certain conditions. We show results from computer simulation for a large range of parameters, although the fertility itself seems to be the most relevant factor.
