Dispersion in Dispersion: Measuring Establishment‐Level Differences in Productivity
介绍了美国劳工统计局和人口普查局联合发布的新实验性生产率离散统计数据集DiSP，该数据补充了官方行业层面生产率统计，揭示了制造业行业内企业间生产率的巨大差异，并发现1997至2016年间离散度上升且呈逆周期特征。
Abstract We describe new experimental productivity dispersion statistics, Dispersion Statistics on Productivity (DiSP), jointly produced by the Bureau of Labor Statistics (BLS) and the Census Bureau, that complement the official BLS industry‐level productivity statistics. The BLS has a long history of producing industry‐level productivity statistics, which represent the average establishment‐level productivity within industries when appropriately weighted. These statistics cannot, however, tell us about the variation in productivity levels across establishments within those industries. Dispersion in productivity across businesses can provide information about the nature of competition and frictions within sectors and the sources of rising wage inequality across businesses. DiSP data show enormous differences in productivity across establishments within industries in the manufacturing sector. We find substantial variation in dispersion across industries, increasing dispersion from 1997 to 2016, and countercyclical total factor productivity dispersion. We hope DiSP will enable further research into understanding productivity differences across industries and establishments and over time.
