| Abstract: | The purpose of this analysis is to shed some light on the issue of how much economic growth, unaided by population control policies, can bring down fertility and defuse the population explosion in the less developed countries. The paper explores the demographic evolution of an ideal less developed country over a 100 years time span under alternative assumptions concerning capital accumulation, rate of technological progress, and returns to scale. The model used incorporates (a) a population projection matrix with coefficients which are a function of time and of endogenously generated levels of income per capita, and (b) a gross reproduction rate‐GNP per capita function with parameters estimated from a time series of cross sections spanning the period 1860 to 1959. This function was designed to reflect dominant traits of the historical experience concerning the effects of economic growth on fertility in a context characterised by the absence of population control policies. |
