Now let’s shift our focus to the period from 1990 to 2004, when the major
buildup in China trade occurred. During these most recent 14 years, the US lost 3.3
million manufacturing jobs (Table 1). Meanwhile, total output in manufacturing in the
US was increasing by more than 50% (i.e., the index went from 75.0 to 117.0), and
output per worker in manufacturing was increasing by 73% (i.e., the index of output per

Page 7
worker in US manufacturing went from 100.00 to 173.34; see Table 2, below). To better
understand these changes, I apply "Job Shift Analysis", a simple technique patterned
after shift-share analysis.
Job Shift Analysis of US Manufacturing Employment Losses 1990-2004
In the Job Shift Analysis model, we are trying to address four sets of changes that
are affecting manufacturing job growth/decline in a country (in the present paper, for the
USA in Section I and for China in Section III):
1. Static job losses in the manufacturing sector from productivity growth;
2. Implied, potential manufacturing job gains from GDP growth;
3. Manufacturing job losses from structural changes such as the shift to
producing less labor-intensive goods, the increasing demand for services
relative to goods, and the related shift of existing jobs and of GDP-
induced job growth to other sectors of the economy;
4. Gains (losses) of jobs due to competitive manufacturing advantages
(disadvantages) experienced by the home country.
Competitive advantages in a particular manufactured good can arise from a
number of sources, only some of which are directly related to labor. These non-labor
advantages can include intellectual property attributes and the protections that one
national environment (such as the US) provides compared to another national
environment (such as China or Argentina). They can entail access to final markets, such
as—for example—BMW’s desire to assemble automobiles within the country
representing its most important final market. They can include external economies of
agglomeration or of localization (in the contemporary vernacular, "clustering") arising
from the presence of supply chain partners and other related firms. Likewise, advantages
can grow out of traditional advantage such as access to important natural resources. One
such "natural resource" can be labor related—e.g., productive and/or inexpensive
workers, or a particularly-educated workforce (including innovative and creative people).
And, finally, all such advantages as these can both enjoy and enhance the advantages
provided by a favorable rate of exchange for the national currency.
Labor-based competitive advantages on the cost side (much the objective of data
collection and analysis efforts feeding off of the US Department of Labor’s Foreign
Page 8

CIT Working Paper 052507 (August 4, 2005)
Page 8
Labor Statistics web site http://www.bls.gov/fls/home.htm, from which I take part of my
data for this paper) derive from the interplay between the following components: (1)
Output per hour by manufacturing workers; (2) Total worker costs per hour, denominated
in the local currency; and (3) The effective exchange rate between the local currency and
foreign exchange (often normalized into US Dollars). Together, these are the components
of the labor cost per unit of manufacturing output stated in the common denominator of
US Dollars.
As we discuss again later, productivity can have a negative, direct effect on labor
employment. And productivity can simultaneously have a positive, indirect
effect—subject, of course, to what is happening with local wage costs denominated in the
local currency and the exchange rate that links local costs to the global economy.
Because technology spreads rapidly in a globalized manufacturing economy, it is
possible for every nation to be affected by the direct effect which acts to reduce the
overall number of manufacturing workers needed. With the competitiveness factor, on
the other hand, there will be both gainers and losers. With rapid productivity growth,
only a very few countries will be able to overcome the employment reducing effects with
sufficient competitive gains to make up for those effects. It is my judgment that,
generally, the "winners" in manufacturing job creation/retention will fall into two
categories: (1) Small countries with productive and well-managed economies; and (2)
Previously-inefficient national economies in which market liberalization is making
available large numbers of workers at very low opportunity cost.
With Job Shift Analysis, we can divide the US manufacturing job gains and losses
over time into three groups: (1) Job gains (losses) one would expect from productivity
growth; (2) Job gains (losses) one would expect from growth in GDP; and (3) A residual
category intended to capture job gains (losses) from the combination of structural and
competitive changes outlined above and not included in the first two parts of the Job
Shift Analysis calculation. As I demonstrate below, this paper’s application of Job Shift
Analysis suggests that productivity growth in manufacturing dominates the overall
manufacturing job losses by the US during the period 1990-2005.

We start by asking the simple question: "Given the productivity growth from
1990 to 2004, how many manufacturing workers would be needed in 2004 to produce the
same output as 1990?" We can use this simple question to calculate the "Productivity
Factor" effect on job growth (loss) during the period:
Productivity Factor = 17.695 x (100.00/173.34) – 17.695 = – 7.5 mil. jobs
What this first calculation tells us is that, in static terms, the US lost 7.5 million jobs to
productivity growth during the period 1990-2004. This amounted to more than 40% of
the manufacturing jobs that existed in the US in 1990.
If the US economy of 2004 otherwise looked just like the US economy of 1990,
that would be fine. But in that interim, GDP grew by 56% (the same rate as the growth
in manufacturing output during that same period, incidentally). Based on the 56% growth
in GDP, the economy should have added back 5.7 million manufacturing jobs (based on
the ‘new’ manufacturing productivity levels of 2004):
GDP Growth Factor = (17.695 – 7.5) x 0.56 = + 5.7 mil. jobs
In other words, after the effect of productivity growth, we should have had
(17.695 million – 7.5 million = 10.2 million) manufacturing jobs to supply the 1990 level
of US manufacturing output. Growth of 56% in GDP should have added back (at the
new productivity levels) by a factor of (10.2 million x 0.56 = 5.7 million). Combine the
Page 10
W. Ward
CIT Working Paper 052507 (August 4, 2005)
Page 10
GDP growth effect with the job losses from productivity growth and you get a net loss of
–1.8 million manufacturing jobs:
GDP Growth Factor – Productivity Growth Factor = (5.7 – 7.5) = – 1.8 mil jobs
The above calculation tells us that during this 14-year period, GDP did not grow
sufficiently to add back the manufacturing jobs in the US that were lost to productivity
growth during that same period. But the actual job losses were greater than the 1.8
million calculated above, raising the question of what happened to the other 1.5 million
(of the 3.3 million) manufacturing jobs that were lost from 1990-2004? In this analysis, I
attribute those losses to Competitive and Structural Factors affecting the US economy.
Competitive & Structural Factors = – 3.3 million – (– 1.8 million) = – 1.5 million
jobs
One of these competitive and structural factors recognized by others, of course, is
the changing composition of Personal Consumption Expenditures (PCE) in the GDP.
Table 3 shows a continuing and long-developing shift in the balance of PCE from
expenditures on "goods" to expenditures on "services". This shifting balance would
affect manufacturing employment adversely, since the manufacturing sector produces the
bulk of the goods that go into that part of the PCE accounting. Because of the shifting
balance in PCE, one should not expect all of GDP growth effect to go straight into
creating new manufacturing jobs, since ‘services’ production and consumption in the
GDP accounts grew faster than ‘goods’ production and consumption in those same
accounts.

Indeed, there is some evidence from our calculations of US competitive gains in the late-1990s that

disappears or goes the other way after 2000.

Still another matter is the competitive effect of growing global manufacturing
competition. Just as in the Shift-Share Analysis alluded to in passing, above, it is
possible to gain an increasing share of jobs with an overall sector or industry that actually
is in secular decline globally.
Had the US manufacturers been gaining significant global competitive advantage
during the period we are analyzing, we might have seen net positive numbers resulting
from our Competitive and Structural Factor calculation. We did not, so we might
3
surmise that the US did not secure sufficient competitive gains during full period 1990-
2004 to make up for the net manufacturing job losses shown for the sum or our
Productivity and GDP Growth Factor calculations. Of course, the global competitiveness
of US manufacturers is more complicated than worker productivity alone (including
negotiated wage agreements, taxation, and exchange rate issues as well, for example).
Meanwhile, compare the United States economy’s 1.5 million manufacturing job
losses from competitive and structural factors to the 7.5 million lost to productivity
growth. From this comparison, I conclude that, during the period 1990 to early-2005, US
manufacturing productivity growth cost the US several times more manufacturing jobs
than all other factors combined—including global competition.
Page 12
Further buttressing confidence in our calculation is the fact that the Index of Manufacturing Output (Table
4
1) stood at about the same level at the end of 2004 as in 2000 (more on this point below).

Job Shift Analysis of US Employment Changes 2000-2005
Before we go on to look at other issues such as manufacturing sector trends in
other countries, let us refine our Job Shift Analysis to look at the period from 2000 to
early-2005, the period during which 83% of the overall US job losses in manufacturing
alluded to above occurred. This particular application of Job Shift Analysis reveals some
striking outcomes on the interplay between productivity growth and economic
adjustments in the US economy.
Using the same data tables and Job Shift Analysis algorithms as previously, we
get the following results:
Productivity Growth Factor (2000 to 2005): – 3.005 million jobs
GDP Growth Factor (2000 to 2005): + 1.831 million jobs
Total Actual Job Gains or Losses (2000 to 2005): – 3.005 million jobs
Competitive & Structural Factor (2000 to 2005): – 1.831 million jobs
This application of Job Shift Analysis tells us something very interesting about
the period after 2000, because the actual job losses in manufacturing during that period
match up closely with losses we would have expected from productivity growth alone.

In addition to being a period of rapidly rising manufacturing exports by China, the
2000-2005 interval also was a period of particularly high productivity growth in
manufacturing in the US (and, as we show in Section III, in the larger world as well—See
Table 2 and Table 9). According to this second application of Job Shift Analysis, 100%
of the US manufacturing job losses from the base point of 2000 were due to productivity
growth. Meanwhile, 100% of the GDP Growth Factor went into creating income and
jobs in OTHER sectors of the US economy (i.e., other than manufacturing) after 2000.
Thus, the period 2000-2005 was a period that was particularly marked by competitive
and structural adjustments in the US economy.
Meanwhile, during the post-2000 period, US GDP rose by about 13%. And the
US index of manufacturing output shown in Table 1 that stood at 117.3 in 2000 was back
Page 13
Appendix Table 1 shows actual net job creation overall in the US economy during 2000-2005 (January to
5
January) of 1.7 million jobs, very close to the 1.831 million jobs that our Job Shift Analysis suggested
should have developed outside of manufacturing but within the overall US economy.

again to 117 (after declining in 2001-2003 and then rising again through 2004).
Productivity growth in that period took away three million manufacturing jobs—the
number of manufacturing jobs actually lost in the period. The GDP Growth Factor
should have created 1.831 million new jobs—but they were not in manufacturing . So,
5
where were they?
Section II. Index of Job Quality Changes in the US
Table 4 shows that the job losses in the US economy between 2000 and early 2005
occurred in manufacturing (about 3 million jobs), in "information" (434,000), in
wholesale trade (279,000), in retail trade (134,000), in transport and warehousing
(50,000), and in utilities (31,000). Meanwhile, 2.2 million net jobs were developing in
education and health services, 1.1 million in government (presumably paralleling the
overall average of two-thirds of them being in local government), and almost a million in
Leisure and Hospitality. All-in-all, the Bureau of Labor Statistics recorded net job
growth of 1.7 million in the US economy as counterpart to the GDP growth of 13%
between 2000 and early-2005. This suggests that the two largest employment substitutes
for manufacturing jobs lost during 2000-2005 were (a) Education and Health Services,
and (b) Government. Take Government out of the job accounts, and fewer than 0.6
million private sector net new jobs were created in the US after January 2000 (Therefore,
the application of the term "jobless recovery" following the recovery from the 2001
economic downturn). US GDP grew by 13% after 2000, and the US civilian workforce
grew by about 3.3% (i.e., from 142.6 million in 2000 to 147.4 million in 2004, according
to BLS data). However, US civilian employment grew less than one-half of one percent
(i.e., 600,000 divided by 137 million) during that period.

To see how the pattern of job gains and losses affected the overall quality of net new
employment created in the US economy from January 2000 to January 2005, I created an
"Index of Job Quality Change" in which job changes in each (private) sector were
multiplied by the average hourly compensation for that respective sector, and the sum of
these products was then divided by the product of total private sector job change
multiplied by the private sector average hourly compensation (for January 2005, as
reported by BLS). I then calculated the Index for each of the intervals we have been
analyzing and present the Index calculation for the post-2000 period in Table 5. In Table
6, the results of calculations of the Index of Job Quality Changes for the 1990-1995 and
the 1995-2000 periods also are presented.

Index of Job Quality Change (2000-2005): (1,544/9,386) = 0.16
The Index of Job Quality Changes for the periods 1990-1995 and 1995-2000
presented in Table 6 show striking differences between these two earlier intervals versus
the post-2000 period results that were calculated in Table 5. Indeed, the positive job
quality performance of the 1995-2000 period (Index of 1.03) stands in stark contrast to
the very negative job quality performance of the US economy after 2000 (Index of 0.16).
Driving this dramatic change in my Index for 1995-2000 versus the Index for 2000-2005
was the decline in relative importance of newly-tradable services such as Professional
and Business Services and the increase in relative importance of less-tradable services
such as Education and Health Services, and Leisure and Hospitality between these two
periods. This suggests to me two things: (1) The importance of the "sectoral reallocation"
modeling that is being done by a number of analysts, particularly in conjunction with the
Chicago Fed; and (2) The importance of broadening that work to include global data and

analysis on employment change. My Section III should make clear the importance of
this second suggestion.

Section III. Manufacturing in China and the Rest of the World
Let us begin Section III with a look at the World Bank’s World Development
Indicators 2005 data on "Industry" employment as a percent of total employment for the
most industrialized of the Bank’s member countries. From the WDI 2005 data, we see a
dramatic shift in the proportion of workers employed in industry versus services in the
middle- and high-income countries during the decade ending in 2000-2002. In the
middle-income countries, the proportion of workers employed in industry declined by a
third during that decade, while in the high-income countries the proportion declined by
half (Table 7).
