The contribution of robots to productivity growth in 30 OECD countries over 1975–2019

Abstract

Using a new and original database, our paper contributes to the growth accounting literature by singling out the contribution of robots through two channels: capital deepening and TFP. The contribution of robots to productivity growth through capital deepening and TFP appears to have been significant in Germany and Japan in the sub-period 1975–1995 and in several Eastern European countries in 2005–2019. However, robotization does not appear to be the source of a significant revival in productivity.
