The past three decades have seen unprecedented technological development, with major impacts on labour markets and the economy as a whole. This column investigates how automation and the increased use of computers has affected productivity trends over the last three decades. Results suggest that automation has had a strong effect on slowing down aggregate productivity, despite raising it at the micro level. This is due to the reallocation of factor inputs across occupations and industries.

Mounting evidence suggests that average mark-ups in the US economy have been increasing. This column argues that about half of measured aggregate productivity growth over the last 20 years can be accounted for by firms with higher mark-ups increasing their relative size. This implies that the slowdown in pure technology growth is even slower than suggested by aggregate productivity statistics. Eliminating mark-ups would increase the productivity of the US economy by about 40%.
