Job Polarization and Task-Biased Technological Change : Evidence from Sweden, 1975–2005

• This paper shows that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle-wage jobs. The most popular explanation for such a pattern is the hypothesis of ‘task-biased technological change’, where technological progress reduces the demand for routine middle-wage jobs but increases the demand for non-routine jobs located at the tails of the job-wage distribution. Our estimates, however, do not support this explanation for the 1970s and 1980s. Stronger evidence for task biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non-routine jobs and a decline of routine jobs. Results for wages are, however, mixed; while task-biased technological change cannot explain changes in between-occupation wage differentials, it does have considerable explanatory power for changes in within-occupation wage differentials.
