Here is another Brookings article talking about the “internet of things” and productivity.
Nearly 30 years ago, the economists Robert Solow and Stephen Roach caused a stir when they pointed out that, for all the billions of dollars being invested in information technology, there was no evidence of a payoff in productivity…
By the late 1990s, the economists Erik Brynjolfsson and Lorin Hitt had disproved the productivity paradox, uncovering problems in the way service-sector productivity was measured and, more important, noting that there was generally a long lag between technology investments and productivity gains.
Our own research at the time found a large jump in productivity in the late 1990s, driven largely by efficiencies made possible by earlier investments in information technology. These gains were visible in several sectors, including retail, wholesale trade, financial services, and the computer industry itself. The greatest productivity improvements were not the result of information technology on its own, but by its combination with process changes and organizational and managerial innovations.
So we can expect a delayed productivity effect. The real question to me is not just whether this will happen, but whether the productivity gain will translate into better quality of life for most people. If productivity per hour of work goes up, that would mean economic growth if people keep working the same amount. But it can instead mean there are fewer jobs for people to do. A small number of companies and individuals might then reap the benefits, and it might not benefit the average person.
