Summary: “Is the economy in technological stagnation? Or will computers take all our jobs?” An analysis from the Fed gives us an answer. Another in a series of posts about the future of America’s economy and the coming of the next industrial revolution.
“The Productivity Paradox: Is Technology Failing or Fueling Growth?”

“Is the economy in technological stagnation? Or will computers take all our jobs?”
The U.S. economy has grown slowly since the recession ended in 2009, more slowly than in past recovery periods. The depth of the recession, and the financial crisis that exacerbated it, surely explain this sluggishness — right? Not according to some economists, who think we have a bigger problem on our hands: that the underlying dynamics of the economy are impaired and our ability to innovate new technologies is the root cause of the current stagnation. In other words, they argue, slow growth is the new normal.
But other economists take the opposite stance. These economists say that technology is improving so rapidly that machine intelligence and automation will replace much of human labor. And while overall growth will improve, technology is bound to radically reshape our economy, making it more unequal.
Which story is correct? Let’s look at some evidence found in long-run trends. …
That’s an important question, about which he provides an excellent summary. It is also discussed in several posts (links below). But it’s not our focus today.
Labor market implications
Considering these competing views on productivity and technology, we come to the most salient economic issue of our time: jobs. The rate of technological innovation obviously has major labor market effects. What is the relationship between new technological advances and the current skill distribution of the labor force?
Skill-biased technical change is the economic theory for how advances in technology can increase worker productivity, given compatible skills, but how they also displace certain workers. Think of the automation improvements in U.S. manufacturing. Total inflation-adjusted manufacturing production has never been higher than it is now, and manufacturing productivity, if anything, increased following World War II. But the total number of persons employed in manufacturing industries fell sharply, even more so as a percentage of the labor force.
… Cowen and the authors of Race Against the Machine foresee skill-biased technical change as accelerating in the future. They see the fruits of this third industrial revolution — information technology — as having just begun to disrupt the labor market.
This view is augmented by the recent research of David Autor, an MIT economist, who highlights a slightly different, and perhaps more disturbing, phenomenon: labor market polarization. Autor and his coauthors document the rise in demand for both high- and low-skill occupations alongside a decline in demand for middle-skill workers. They then tie technological automation to this erosion of middle-skill occupations. Manufacturing is one big area where these middle-skill jobs exist.
… If the techno-optimists are correct about the future, the combination of skill-biased technical change and greater labor market polarization will complicate the already serious state of the U.S. labor market.
