Market Selection, Reallocation, and Restructuring in the U.S. Retail Trade Sector in the 1990s
利用美国零售贸易部门的企业数据，量化了1990年代该部门的重组与重新配置如何推动劳动生产率增长，发现几乎全部增长来自高生产率新企业替代低生产率退出企业，尤其是大型全国连锁店替代小型单店。
The U.S. retail trade sector underwent a massive restructuring and reallocation of activity in the 1990s with accompanying technological advances. Using a data set of establishments in that sector, we quantify and explore the relationship between this restructuring and reallocation and labor productivity dynamics. We find that virtually all of the labor productivity growth in the retail trade sector is accounted for by more productive entering establishments displacing much less productive exiting establishments. The productivity gap between low-productivity exiting single-unit establishments and entering high-productivity establishments from large, national chains plays a disproportionate role in these dynamics.
