Abstract

This paper brings together and analyses the results of empirical analyses which, in contrast to most other studies, find that trade has been a significant cause of labour market inequality in various industrialised countries. The approach is based upon the concept of outsourcing – whereby the low-skill parts of the production chain are ‘outsourced’ to low-wage countries. A distinguishing feature of the empirical work is the use of highly detailed trade data, which allow imports from high- and low-wage countries to be separately identified at the industry level. Using cost minimisation framework, we show that imports from low-wage countries have made a significant contribution to the decline in the wage-bill share and/or relative employment of less-skilled workers in the UK, the USA, Sweden and Italy. We also show how the country-specific characteristics of outsourcing can lead to quite different inequality outcomes in different countries. In line with other studies, we also find that technology has played an important role in causing the increase in inequality in many countries. However, there is also some evidence that some of the rapid increase in the application of new technologies in recent decades has been trade-induced through mechanisms such as 'defensive innovation'.
