Productivity dispersion, wage dispersion and superstar firms
基于2000-2016年14个欧盟国家的企业数据，研究发现生产率、工资离散度和超级明星企业均上升，且超级明星企业主导的行业生产率向工资的传导更弱，这一现象在可贸易部门和集体谈判力量弱的市场中更明显。
Abstract Using a rich sample of firms in 14 EU countries from 2000 to 2016, we confirm increases in productivity dispersion, wage dispersion and superstar firms. Beyond reaffirming an incomplete pass‐through from productivity to wages, we present novel empirical evidence of an even weaker pass‐through in industries dominated by superstar firms. This effect is observed in both the lower and upper parts of the productivity and wage distributions, and is stronger for tradable (versus non‐tradable) sectors and markets with low (versus high) collective bargaining power. These findings point to different mechanisms, consistent with theoretical work and various underlying structural changes in the economy.
