Across small-scale societies, the exercise of about males taking multiple wives is idea to hold upward associated amongst extreme disparities of wealth. But inwards fact, polygyny has been to a greater extent than mutual amid relatively egalitarian low-tech horticulturalists than inwards highly unequal, capital-intensive agricultural societies. This surprising fact is known every bit the polygyny paradox, in addition to a novel report from the Santa atomic issue 26 Institute's Dynamics of Wealth Inequality Project provides a possible resolution of the puzzle.

Their principal finding is that where wealth is highly concentrated, few men are wealthy plenty to afford to a greater extent than than a unmarried wife, in addition to the really wealthy, patch ofttimes polygynous, create non create got on wives inwards proportion to their wealth.
Cody Ross (Max Planck Institute for Evolutionary Anthropology), a quondam Santa atomic issue 26 Institute postdoctoral boyfriend along amongst Santa atomic issue 26 Institute Professor Samuel Bowles in addition to University of California anthropologist Monique Borgerhoff Mulder led the squad of 34 anthropologists in addition to economists conducting the study.
"In many capital-intensive farming societies," Bowles explained, "there are then few sufficiently wealthy men that unless they were to create got a really extraordinary issue of wives, exclusively a small-scale fraction of all women volition hold upward married polygynously."
Like previous studies, including those yesteryear Laura Fortunato (Santa atomic issue 26 Institute, University of Oxford) in addition to others, the model developed yesteryear the squad takes job organisation human relationship of the fact that taking on additional wives reduces the sum of a male's textile wealth -- land, cattle, equipment -- available to each wife.
But the novel report showed that the impediments to polygyny fifty-fifty amid the really rich went agency beyond the necessitate to part the male's wealth amid competition wives. "This is what actually surprised us," said Borgerhoff Mulder. "Our estimates demo that a really rich human being amongst iv wives volition create got far fewer kids than ii men amongst ii wives in addition to amongst the same full wealth divided betwixt them."
The report is published inwards the Journal of the Royal Society Interface.
