Wages and Unemployment in an Urban African Labour Market
利用科特迪瓦数据，发现非洲城市劳动力市场存在工资曲线：失业率上升会压低工资，这与发达国家类似，支持效率工资理论。
This paper argues that urban labour markets in Africa exhibit a wage curve similar to those found in the United States, Britain, Canada and other Developed Countries. Drawing on data from Côte d'Ivoire, it finds that urban wages are depressed by higher levels of unemployment. This result is robust to changes in model specification and level of aggregation. It is consistent with the model of wage determination developed by Shapiro and Stiglitz (1984) and Blanchflower and Oswald (1995), but not with claims that urban wages are invariant to unemployment.
