This paper presents a quantitative analysis of the model developed in Galor and Moav, Natural Selection and the Origin of Economic Growth (2002), in which agents vary genetically in their preference for quality and quantity of children. We simulate a parametric form of the model, enabling examination of the transition from Malthusian stagnation to modern rates of economic growth. The simulations allow an assessment of the strength of the biological foundations of the model and demonstrate the susceptibility of the modern high-growth state to invasion by cheaters. Extending the model from two to three genotypes suggests the possibility of a return to Malthusian conditions rather than a permanent state of modern growth.
