Productivity is falling globally: “Internet of Everything” is everywhere except in the productivity statistics

The productivity paradox is back. Productivity is falling globally, especially in the US and China.“Internet of Everything” is everywhere except in the productivity statistics

Those of us that are immersed in the innovation economy may find this hard to believe, but we are not, as a whole, actually more productive when we are in the midst of an innovation cycle boom. New technologies take time to absorb, refine and make mainstream. Computer software can be reprogrammed quickly. Humans can’t.

Optimists maintain that the official statistics fail to capture marked quality-of-life improvements, which may be true, especially in the light of promising advances in biotechnology and online education. But this overlooks a much more important aspect of the productivity-measurement critique: the undercounting of work time associated with the widespread use of portable information appliances.
In the US, the Bureau of Labor Statistics estimates that the length of the average workweek has held steady at about 34 hours since the advent of the Internet two decades ago. Yet nothing could be further from the truth: knowledge workers continually toil outside the traditional office, checking their email, updating spreadsheets, writing reports, and engaging in collective brainstorming. Indeed, white-collar knowledge workers – that is, most workers in advanced economies – are now tethered to their workplaces essentially 24 hours a day, seven days a week, a reality that is not reflected in the official statistics.
Productivity growth is not about working longer; it is about generating more output per unit of labor input. Any undercounting of output pales in comparison with the IT-assisted undercounting of working hours.

In the late 1980s, there was intense debate about the so-called productivity paradox – when massive investments in information technology (IT) were not delivering measureable productivity improvements. That paradox is now back, posing a problem for both the United States and China – one that may well come up in their annual Strategic and Economic Dialogue.
Back in 1987, Nobel laureate Robert Solow famously quipped, “You can see the computer age everywhere except in the productivity statistics.” The productivity paradox seemed to be resolved in the 1990s, when America experienced a spectacular productivity renaissance. Average annual productivity growth in the country’s nonfarm business sector accelerated to 2.5% from 1991 to 2007, from the 1.5% trend in the preceding 15 years. The benefits of the Internet Age had finally materialized. Concern about the paradox all but vanished.
But the celebration appears to have been premature. Despite another technological revolution, productivity growth is slumping again. And this time the downturn is global in scope, affecting the world’s two largest economies, the US and China, most of all.
Over the past five years, from 2010 to 2014, annual US productivity growth has fallen to an average of 0.9%. It actually fell at a 2.6% annual rate in the two most recent quarters (in late 2014 and early 2015). Barring a major data revision, America’s productivity renaissance seems to have run into serious trouble.
China is witnessing a similar pattern. Although the government does not publish regular productivity statistics, there is no mistaking the problem: Overall urban employment growth has been steady, at around 13.2 million workers per year since 2013 – well in excess of the government’s targeted growth rate of ten million. Moreover, hiring seems to be holding at that brisk pace in early 2015.
At the same time, output growth has slowed from the 10% trend of the 33 years ending in 2011 to around 7% today. That downshift, in the face of sustained rapid job creation, implies an unmistakable deceleration of productivity.
Therein lies the latest paradox. With revolutionary technologies now driving the creation of new markets (digital media and computerized wearables), services (energy management and DNA sequencing), products (smartphones and robotics), and technology companies (Alibaba and Apple), surely productivity growth must be surging. As a modern-day Solow might say, the “Internet of Everything” is everywhere except in the productivity statistics.
But is there really a paradox? Northwestern University’s Robert Gordon has argued that IT- and Internet-led innovations like automated high-speed data processing and e-commerce pale in comparison to the breakthroughs of the Industrial Revolution, including the steam engine, electricity, and indoor plumbing. He maintains that, although these innovations led to dramatic transformations of the major advanced economies – such as higher female labor-force participation, increased transportation speed, urbanization, and normalized temperature control – these changes will be extremely hard to replicate.
Indeed, as taken with today’s revolutionary technologies as we are – I say this staring at my sleek new Apple Watch – I am sympathetic to Gordon’s argument. If US productivity figures are to be taken at anything close to face value – a persistently sluggish trend interrupted by a 16-year spurt that now appears to have faded – it is possible that all America has accomplished are transitional efficiency improvements associated with the IT-enabled shift from one technology platform to another.–roach-2015-06
