Wages and Labor Management in African Manufacturing
利用十个非洲国家的雇主-雇员匹配数据，研究工资、工人监督与劳动生产率的关系，发现监督和工资对努力程度及生产率有显著影响，且非洲的监督比例和弹性高于其他地区。
Abstract Using matched employer-employee data from ten African countries, we examine the relationship between wages, worker supervision, and labor productivity in manufacturing. Wages increase with firm size for both production workers and supervisors. We develop a two-tier model of supervision that can account for this stylized fact and we fit the structural model to the data. We find a strong effect of both supervision and wages on effort and hence on labor productivity. Labor management in sub-Saharan Africa appears problematic, with much higher supervisor-to-worker ratios than elsewhere and a higher elasticity of effort with respect to supervision than in Morocco.
