On Kin Groups and Wages in the Ghanaian Labour Market
研究加纳劳动力市场中亲属群体偏袒对工资的影响，发现私营部门按人力资本付薪，而公共部门存在约25%的亲属群体工资溢价。
A common feature of African societies is that individuals belong to kin groups which impose reciprocal obligations upon their members. In the modern economy, where large scale production is required, forms must employ multiple kin groups. In such cases kin groups will try to favour their own members in the assignment of good jobs. We analyze the effects of kin group patronage in the modern sector. We set out a model in which kin group favouritism is shown to give rise to a wage premium for the largest kin group. We then use an unusually rich data set from Ghana to test for kin group favouritism, empirically distinguishing it from ‘taste for discrimination’. We find that in the private sector there is no evidence for kin group patronage and earning functions (corrected for selection into the various sectors) reveal that workers are paid according to their human capital attributes. By contrast, public sector workers are rewarded for their credentials and membership of the right kin group, not for their productive characteristics. The kin group premium is about 25 percent and is statistically robust to alternative specifications.
