Abstract
AbstractThe routine task intensity of occupations is a concept frequently used to analyse the impact of technological change on employment. However, existing studies disagree on whether it can explain the observed job polarization in advanced economies. This article first shows that these seemingly contradictory results can be explained by the different routine task measurements used in these studies. Subsequently, the validity of these measurements is discussed. Preliminary results suggest that all measurements have conceptual weaknesses but that some appear more valid than others. Job polarization may therefore be explained by occupations' routine task intensity, but only to a limited extent.
