Decomposing the Labour Productivity Gap between Migrant-Owned and Native-Owned Firms in Sub-Saharan Africa
利用20个非洲国家的企业数据，发现移民所有企业的劳动生产率比本土企业高78%，其中80%的差距由结构性因素解释，管理者教育回报是主要驱动因素。
Migration studies have been primarily based on the movement of individuals from developing to developed economies, with a focus on the impact of migrants on host country wages. In this study we take a different angle by exploring the labour productivity of migrant-owned firms versus native-owned firms in 20 African economies using firm-level data. We find that labour productivity is 78 per cent higher in migrant-owned firms than native-owned firms. Using the Oaxaca-Blinder decomposition method we find that structural effects account for 80 per cent of the labour productivity gap. Returns to manager education largely explain the productivity advantage of migrant-owned firms over native-owned firms. Interactions with the government, access to finance, informality, and power outages are also considerable contributors to the labour productivity gap.
