The Productivity Paradox:
"Despite the economy's stunning 8.2 percent surge in the third quarter, the staying power of this economic recovery remains a matter of debate. But there is one aspect of the economy on which agreement is nearly unanimous: America's miraculous productivity. In the third quarter, productivity grew by 8.1 percent in the nonfarm business sector — a figure likely to be revised upwards — and it has grown at an average rate of 5.4 percent in the last two years."

This surge is not simply a byproduct of the business cycle, even accounting for the usual uptick in productivity after a recession. In the first two years of the six most recent recoveries, productivity gains averaged only 3.5 percent. The favored explanation is that improved productivity is yet another benefit of the so-called New Economy. American business has reinvented itself. Manufacturing and services companies have figured out how to get more from less. By using information technologies, they can squeeze ever increasing value out of the average worker.

It's a great story, and if correct, it could lead to a new and lasting prosperity in the United States. But it may be wide of the mark.

First of all, productivity measurement is more art than science — especially in America's vast services sector, which employs fully 80 percent of the nation's private work force, according to the United States Bureau of Labor Statistics. Productivity is calculated as the ratio of output per unit of work time. How do we measure value added in the amorphous services sector?

Very poorly, is the answer. The numerator of the productivity equation, output, is hopelessly vague for services. For many years, government statisticians have used worker compensation to approximate output in many service industries, which makes little or no intuitive sense. The denominator of the productivity equation — units of work time — is even more spurious. Government data on work schedules are woefully out of touch with reality — especially in America's largest occupational group, the professional and managerial segments, which together account for 35 percent of the total work force.

For example, in financial services, the Labor Department tells us that the average workweek has been unchanged, at 35.5 hours, since 1988. That's patently absurd. Courtesy of a profusion of portable information appliances (laptops, cell phones, personal digital assistants, etc.), along with near ubiquitous connectivity (hard-wired and now increasingly wireless), most information workers can toil around the clock. The official data don't come close to capturing this cultural shift.

As a result, we are woefully underestimating the time actually spent on the job. It follows, therefore, that we are equally guilty of overestimating white-collar productivity. Productivity is not about working longer. It's about getting more value from each unit of work time. The official productivity numbers are, in effect, mistaking work time for leisure time.…
