Sexual economic theory and the human mating market

In this study, we apply economic principles to the heterosexual human mating market using data on the socio-demographics, biology, attractiveness, sexual behaviour, and reproductive history of 3,261 Australian online dating participants. More specifically, by using survey participants attractiveness ratings as a proxy for market value, we are able to quantitatively explore theories of sexual economics (SET), which conceptualizes sexual access as an economic resource supplied by women in the human mating market. Our study tests this theory further by incorporating heterosexual market substitutes (namely, 953 bisexual and pansexual individuals) to more accurately integrate the relevant supply and demand forces impacting market value and the commodity of sexual access. We find not only that bisexual and pansexual women (but not men) enjoy a market premium (7.3% higher; p < 0.001) relative to their heterosexual counterparts, but that, contrary to SET, women’s market value in our sample does not diminish with age. We further find that in line with theory and evidence from evolutionary studies, men with (proxied) resources realize a higher market value (6.1% higher for every increased level of educational attainment; p < 0.001) than those without. In conclusion, SET is just one possible model that seeks to understand the complex multi-dimensionality of modern human sexuality and reproduction through an economics lens. As the internet and online dating now provide a low-cost conduit for human mating market participants, so to can it facilitate further large sample scientific studies of mating market dynamics such as this.
