Robots Appear To Raise Productivity Without Causing Total Work Hours To Decline

Hallie Siegel writes: We often read about the economic impact of robots on employment, usually accompanied with the assertion that "robots steal jobs". But to date there has precious little economic analysis of the actual effects that robots are already having on employment and productivity. Georg Graetz (Professor of Economics at Uppsala University) and Guy Michaels (Professor of Economics at the London School of Economics) undertook a study (abstract) of how robots impacted productivity and employment between 1993 and 2007, and found that "industrial robots increase labor productivity, total factor productivity and wages." And while there is some evidence that they reduced the employment of low skilled workers, and, to a lesser extent, middle skilled workers, industrial robots had no significant effect on total hours worked.

This is important because it seems to contradict many of the pessimistic assertions that are presently being made about the impact of robots on jobs. What I am especially curious about is post-2007 data, however, because it's just in the past few years that we have seen a major shift in industrial robotics to incorporate collaborative robots, or co-robots. (Robots specifically designed to work alongside humans, as tools for augmenting human performance.) One might reasonably suspect that some of the negative impact of industrial robotics on low and middle skilled workers pre 2007 could be offset by the more recent and increasing use of co-bots, which are not designed to replace humans, but instead to make them more efficient.

Re:I've said it before

[PopeRatzo]

and I'll say it again - technology INCREASES jobs, never decreases it - over the long term.

If robots don't cause total human working hours to decline, then what the fuck good are they? Are we really automating the work force so people can work more? If so, then please stop with the robots.

Or, maybe we can just dispense with the "robots will make human lives easier" BS and just go straight to "robots will increase profits for people who already have all the fucking money".

Rule of thumb: If there's a human endeavor that doesn't make human lives better, then it is not worth doing.

"crappy, boring, mind-numbingly repetitive tasks"

You might be surprised that this is the extent of the ability for a great number of workers out there. It's easy to forget when you're in an all-white collar environment that there is a large portion of the population which has close to zero independent problem solving ability, and an overlapping portion which has almost zero reliability. As someone who deals with these people on a regular basis, I can tell you that they are some of the nicest people I know, and yet sometime during their lifetime there will be a robot which can do their job better and more reliably at a fraction of what it costs to feed, clothe and house them.

Two factories

Two factories make toilet paper, one introduces robots and doubles its production and also profit margins, the number of employees stays the same. There is no impact to those employees, but the other factory goes out of business. That is where the jobs get lost and that is what the study does not measure. Same amount of toilet paper is produced at twice efficiency and half of the jobs get lost in the overall economy.
