Don’t blame the robots for lost manufacturing jobs
In a recent blog we described new research by George Graetz and Guy Michaels that shows the impact of automation technology in productivity statistics. So now there is good evidence that robots are a driver of economic growth.
However, this new evidence poses a question: Has productivity growth from robots come at the cost of manufacturing jobs?
Between 1993 and 2007 (the timeframe studied by Graetz and Micheals) the United States increased the number of robots per hour worked by 237 percent. During the same period the U.S. economy shed 2.2 million manufacturing jobs. Assuming the two trends are linked doesn’t seem farfetched.
