We examine how changes in task content over time condition occupational wage development. Using survey data from Germany, we document substantial heterogeneity in within-occupational changes in task content. Combining this evidence with administrative data on individual employment outcomes over a 25-year period, we find important heterogeneity in wage penalties amongst initially routine intensive jobs. While occupations that remain (relatively) routine intensive generate substantial wage penalties, occupations with a decreasing routine intensity experience stable or even increasing wages. These findings cannot be explained by composition or cohort effects.
