ABSTRACT

This paper investigates the effects of automation on job polarisation. Automation has been claimed to be one of the main causes for the job polarisation observed in many countries such as the US since the mid-1980s. Using the US Census data, we show that between 1980 and 2007 the increase in the usage of ICT capital is not statistically associated with changes in the employment and wage bill share of routine workers, although there is heterogeneity across industries. The main findings imply that ICT capital per se might not be the main factor driving job polarisation in the US.

就业两极分化是由ICT驱动的吗？来自美国的证据

摘要

本文研究了自动化对工作两极分化的影响。自1980年代中期以来，自动化已被认为是导致许多国家（例如美国）出现工作两极分化的主要原因之一。使用美国人口普查数据，我们可以看到，尽管各行业之间存在异质性，但从1980年到2007年，ICT资本使用量的增加与常规工人的就业和工资账单份额的变化没有统计学关系。主要发现表明，ICT资本本身可能不是导致美国就业两极分化的主要因素。
