The Lion’s Share: An Experimental Analysis of Polygamy in Northern Nigeria
通过在尼日利亚北部进行公共品博弈实验，研究一夫多妻家庭中配偶的行为，发现一夫多妻制并不比一夫一妻制效率低，但男性控制分配时自己获益更多。
We use simple public goods games to investigate spousal behavior in Kano, northern Nigeria, one of the modern heartlands of polygyny. Most partners keep back at least half of their endowment from the common pool, but we find no evidence that polygynous households are less efficient than their monogamous counterparts. When men control the allocation, equal treatment of wives is common, but senior wives often receive more from their husbands, no matter what their contribution. However, the clearest result is that when men control the allocation, polygynous husbands receive a higher payoff compared to their wives and their monogamous counterparts.
