Massive economic growth comes, in large part, from men’s competition to sexually attract women, sort of, suggests this study:
“Sexual selection, conspicuous consumption and economic growth,” Jason Collins, Boris Baer, Ernst Juerg Weber [pictured here], Journal of Bioeconomics, epub May 19, 2015. The authors at the Business School, University of Western Australia, Crawley, Australia, and at the Centre for Integrative Bee Research (CIBER), ARC CoE in Plant Energy Biology, University of Western Australia, Crawley, Australia, explain:
We propose that the evolution by sexual selection of the male propensity to engage in conspicuous consumption contributed to the emergence of modern rates of economic growth. We develop a model in which males engage in conspicuous consumption to send an honest signal of their quality to females. Females prefer males who express the costly and honest signal, leading males who engage in conspicuous consumption to have higher reproductive success than those who do not, increasing the prevalence of signalling males in the population. As males fund their conspicuous consumption through participation in the labour force, an increase in the prevalence of signalling males gives rise to an increase in economic activity that leads to economic growth.
