Biological Market examples
mating markets

For many years I have been rather sceptical about the need of invoking biological market theory (BMT) alongside sexual selection theory (SST). A first paper that made clear that BMT can at least add something to SST, was the paper by Metz et al (2007) on red bishops (see separate page).
Recently, more and more papers on human mating markets citing BMT were published and I still wondered whether anything was added that wasn't already covered by SST. Reading those papers, I started to realise that BMT indeed highlights the strategic adaptation to the agent's own market value, usually dependent on the local operational sex ratio (OSR) better than traditional sexual selection theory does. BMT treats mating markets as dynamic, changing within and between seasons, while SST tends to deal with the effects of the population- or species-typical OSR over evolutionary time scales.
So, finally I wrote a review: Noë, R. (2017). Local mating markets in humans and non-human animals. Behavioral Ecology and Sociobiology, 71(10), 148. In this paper I argue, among other things, that the Operation Sex Ratio (OSR) is the relevant papameter to use when one wants to understand what happens on local mating markets, rather than the Adult Sex Ratio (ASR) that is so heavily promoted lately, notably in a theme issue of the Philosophical Transactions of the Royal Society B: ‘Adult sex ratios and reproductive strategies: a critical re-examination of sex differences in human and animal societies’ compiled and edited by Ryan Schacht, Karen L. Kramer, Tamás Székely and Peter M. Kappeler. For an interesting example of local mating markets in humans see the paper by Prall & Scelza (2022) in Science Advances.
As is well-known for humans, power differentials on mating markets can also have consequences for the power differentials between males and females in aspects of life other than those connected to mating and reproduction (see Chen et al 2024 listed below for a nice example). Rebecca Lewis and colleagues (2023) analysed the connection between sex ratios and the balance of power between males and females in a large sample of extant non-human primate species. They found that females are likely to have more power, when there are relatively few receptive females per male and mating opportunities are therefore in high demand (see also Lewis et al 2022).
Human mating markets
This literature is enormous and new papers are published daily, so this is just a small sample (in chronological order with latest on top)
Chen, Y., Ge, E., Zhou, L., Du, J. & Mace, R. (2024). Gender inequality in workloads explained by operational sex ratio. iScience, 110063 . This paper is not strictly about mating markets but about the influence of the Operational Sex Ratio (OSR) on the division of labour in small villages in China. Thanks to a 'quasi-natural' experiment, a shift in the OSR as a result of men leaving the village to live as monks in monasteries, the authors could show that the men remaining in the villages work less hard the more the sex ratio is female-biased.
