Productivity, the amount of goods and services
produced by Americans in each hour worked, has been growing rapidly, according
to the U.S. Department of Labor. Productivity has been positive for the last
five consecutive quarters in the U.S., a much stronger performance than usual
in times when the economy is soft. The strong growth in productivity that
today's economy is experiencing, however, does not mean a quick upturn in the
near future. Instead, it suggests that a significant share of the increase in economic
efficiency achieved during the boom times of the late 1990s will continue over
the longer term.
In trying to explain the better productivity
numbers, a few economists have observed that companies today are more willing
to quickly lay off thousands of employees than in previous economic slumps. In
some past recessions, many companies have tried to hold on to workers because
hiring and training new ones is costly when the recession is finally over.
Thus, when demand for goods and services fall, leaving less work for the same
number of workers, productivity often drops. Now the practice of retaining
people may be a thing of the past, thereby artificially boosting the
productivity numbers that we are seeing today. Fortunately, most economists
believe that most of the productivity gains are for real and not induced only
by hiring and layoff practices.
Nonetheless, the recent surge in the nation's
productivity has been unusually strong, given that the economic recovery has
been modest by historical standards. The question is whether this means that
the "new economy" has come through the recession essentially intact, or does it
mean that subsequent to a sharp drop in corporate profits, companies have had
no choice but to cut back payrolls?
Comments by Federal Reserve Chairman Alan
Greenspan suggest that he expects productivity growth to remain brisk for at
least another 10 years as more efficient use of information technology spreads
through the economy and as previous productivity-enhancing technologies pay
off. The adoption of electricity, for example, from the late 19th century shows that it takes time for companies
to reorganize the means to more efficiently in order to reap the benefits of
new technologies.
Almost all economists agree with Greenspan's
claim that structural or basic productivity growth in the U.S. has increased
significantly. The controversial issue is by how much. Early last year, many
economists argued that American structural productivity growth was poised to
advance in the 3.0 percent to 3.5 percent range per year. However, that
estimate now appears somewhat too optimistic, since average productivity growth
in the six years since 1995 has recently been revised downward. Nevertheless,
that range still is at least 1.1 percentage points above the average rate of
productivity growth experienced in the previous decades of the 1970s and 1980s.
The Federal Reserve Board has been at the
forefront documenting economic gains from America's surge in productivity
growth. Typically, labor productivity is split into two components for
analytical reasons: capital deepening, meaning that workers are using more
machines; and what is referred to as multi-factor productivity growth, in which
existing resources of capital are used more efficiently. Economists feel that
the latter is a better gauge of true productivity gains in the economy. Studies
have found that outside the computer industry, multi-factor productivity was
essentially flat after 1995, which surprised many analysts. Corporate profits
depend not only on labor productivity, but also on growth in capital
productivity, which fell in the late 1990s because of over investment. So
apparently, most of the productivity gains in the late 1990s can be attributed
to workers using more machines.
Divining the future path of productivity growth
is hazardous. Unless return on investment significantly improves, companies may
remain reluctant to invest in new information technology equipment and in new
research and development projects. That position could harm future productivity
innovationsÑthe key to longer-term productivity gains. The best guess is that
productivity will grow about two percent in the longer-term. The good thing is
that a two percent annual average growth is still a worthwhile improvement on
previous decades and will help boost living standards. On the other hand, two
percent growth in productivity doesn't mean that economic recessions will be a
thing of the past.
