The Contribution of Robots to Productivity and GDP Growth in Advanced Economies Over 1960–2022
摘要
While the employment effects of robots are a matter of vivid debate among economists, only a few empirical studies have looked at their impact on productivity and growth at the country level. This paper provides new estimates of the robots’ contribution to growth in a set of 29 advanced economies countries over the period 1960–2022. Based on a standard growth accounting framework, the user cost of robots is estimated according to two different methodologies. The estimated robots’ contribution to growth largely differs between the two methodologies, suggesting that the value of the stock of robots, the decrease in their quality-adjusted price index or both may be undervalued. These findings call for further research on the robots’ contribution to growth at the country level.
