Monitoring AI and hyper-automation
In a recent study, economists Daren Acemoglu of MIT and Pascual Restrepo of Boston University try to quantify how worried we should be about robots. They examine the impact of industrial automation on the US labor market from 1990 to 2007. They conclude that each additional robot reduced employment in a given commuting area by 3-6 workers, and lowered overall wages by 0.25-0.5%.
A central question about robots is whether they replace human workers or augment them by boosting productivity. Acemoglu and Restrepo’s research is a powerful piece of evidence on the side of replacement. So, brace yourself: According to the International Federation of Robotics, there are already between 1.5-1.75 million industrial robots in operation, and some observers expect that number to more than double by 2025.
Industrial robots are most commonly used in the automotive industry, which accounts for 39% of robot usage in the US. It’s no surprise, then, that workers in America’s Midwestern carmaking capitals have been the most affected by automation.
Assessing the impact of robots on jobs is no simple task. Advances in other kinds of technology, the spread of the internet, and increased trade with China and Mexico also led to changes in the US labor market over the period studied by the economists.
In order to isolate the effect of robots, Acemoglu and Restrepo used a clever statistical trick. They collected data on adoption rates of industrial robots in Europe, and then analyzed what happened to American labor markets by comparing industry trends with their equivalents in Europe. This isolated the changes likely caused by the spread of robots, and not some other factor peculiar to the US.
