A
Morgan Stanley article suggested that revised official government figures on US economic indicators for the last 3 years would show marked changes, mainly downwards. The
figures have just been released and amongst the key changes noted are as follows: (then after that, a comment by
financial journalist, author and listmeister,
Doug Henwood)
Summary of major revisions
The revised data modify the quarterly pattern of real GDP for 1999-2001. Both the previously
published and the revised estimates show GDP growth peaking in the fourth quarter of 1999 and slowing
substantially during the quarters of 2000. However, the revised estimates show declines in GDP for each
of the first three quarters of 2001, whereas the previously published estimates showed positive but
decelerating growth in the first half of 2001 and a decline in the third quarter. Both sets of estimates
show GDP growth resuming in the fourth quarter of 2001.
The most important differences between the revised and the previously published estimates for
1999-2001 are the following:
The annual rate of growth of real GDP from 1998 to 2001 was revised down from 3.1 percent to
2.7 percent. The annual rate of growth of real GDP from 1998:IV to 2002:I was revised down
from 2.8 percent to 2.4 percent. The largest contributors to the downward revisions were
downward revisions to the growth of personal consumption expenditures (PCE) and of
nonresidential fixed investment.
For 2001, the revised estimates show real GDP growth of 0.3 percent; the previous estimate was
1.2 percent. Lower growth of PCE and larger declines in nonresidential fixed investment and in
change in private inventories accounted for most of the revision.
As described above, the revised estimates show a longer downturn in real GDP than the
previously published estimates. The percent change at an annual rate in real GDP was revised
down from 1.3 percent to -0.6 percent for the first quarter of 2001, was revised down from 0.3
percent to -1.6 percent for the second quarter of 2001, and was revised up from -1.3 percent to
-0.3 percent for the third quarter of 2001.
For 2001, personal income was revised down 0.4 percent. Wages and salaries was revised down
2.9 percent, and personal interest income was revised up 9.8 percent.
Revisions to 1999-2001 estimates
The percent change from the preceding year in real GDP was unrevised at 4.1 percent for 1999,
was revised down from 4.1 percent to 3.8 percent for 2000, and was revised down from 1.2 percent to
0.3 percent for 2001.
For 2000, the largest contributors to the downward revision to real GDP growth were fixed
investment in equipment and software, PCE for nondurable goods, and PCE for durable goods; the
contributions of these components were partly offset by an upward revision to change in private
inventories. For 2001, the largest contributors to the downward revision to real GDP growth were PCE
for services, equipment and software, change in private inventories, and state and local consumption
expenditures and gross investment; the contributions of these components were partly offset by an
upward revision to federal consumption expenditures and gross investment.
The percent change from fourth quarter to fourth quarter in real GDP was revised down from 4.4
percent to 4.3 percent for 1999, was revised down from 2.8 percent to 2.3 percent for 2000, and was
revised down from 0.5 percent to 0.1 percent for 2001. For 2000, the downward revision was mainly
accounted for by slower growth in PCE and private fixed investment. For 2001, the downward revision
was mainly accounted for by slower growth in PCE and a decrease, rather than an increase, in net exports
during the year.
The largest downward revision to the percent changes in real GDP for the quarters of 1999-2001
was 1.9 percentage points (first and second quarters of 2001); the largest upward revision was 1.0
percentage point (third and fourth quarters of 2001). The average revision to the quarterly percent
changes in this annual revision was 0.9 percentage point (without regard to sign); the revisions without
regard to sign to the quarterly percent changes in the annual NIPA revisions from 1979 through 2001
averaged 0.7 percentage point.
From its cyclical trough in the first quarter of 1991 to the fourth quarter of 2000, GDP expanded at
an average annual rate of change of 3.5 percent. Real GDP reached a peak in the fourth quarter of 2000;
GDP then decreased a total of 0.6 percent (0.8 percent at an average annual rate) in the first three
quarters of 2001. GDP increased 2.7 percent at an average annual rate in the fourth quarter of 2001.
The percent change from the preceding year in the price index for gross domestic purchases was
unrevised at 1.5 percent for 1999, was revised down from 2.6 percent to 2.5 percent for 2000, and was
revised up from 1.7 percent to 1.9 percent for 2001. The largest upward revision to the percent change
in the price index for the quarters of 1999-2001 was 0.6 percentage point (first quarter of 2001); the
largest downward revision was 0.5 percentage point (first quarter of 2000).
Current-dollar GDP was revised up $5.7 billion, or 0.1 percent, for 1999; was revised down $48.3
billion, or 0.5 percent, for 2000; and was revised down $125.9 billion, or 1.2 percent, for 2001. The
percent change from the preceding year was revised up from 5.5 percent to 5.6 percent for 1999, was
revised down from 6.5 percent to 5.9 percent for 2000, and was revised down from 3.4 percent to 2.6
percent for 2001. Current-dollar GNP (GDP plus net income receipts from the rest of the world) was
revised up $35.3 billion, or 0.4 percent, for 1999; was revised down $12.8 billion, or 0.1 percent, for
2000; and was revised down $98.7 billion, or 1.0 percent, for 2001. Net income receipts was revised up
for all 3 years: $29.5 billion for 1999, $35.5 billion for 2000, and $27.2 billion for 2001. The revisions
to net income receipts -- which affect GNP, national income, corporate profits, net interest, and personal
interest income -- stem from the revisions to BEA's international transactions accounts (ITA's) that were
released in June. Although the revisions to the ITA's extended back to 1993, the revisions prior to 1999
are not incorporated into the NIPA's at this time. (An article describing the revisions to the ITA's was
published in the July 2002 issue of the Survey of Current Business.)
National income was revised up $6.6 billion, or 0.1 percent, for 1999; was revised up $3.5 billion,
or less than 0.1 percent, for 2000; and was revised down $95.5 billion, or 1.2 percent, for 2001. For
1999, upward revisions to net interest, to nonfarm proprietors' income, and to rental income of persons
were partly offset by a downward revision to corporate profits. For 2000, a large upward revision to net
interest and smaller upward revisions to nonfarm proprietors' income, to other labor income, and to rental
income of persons were partly offset by a large downward revision to corporate profits and a smaller
downward revision to farm proprietors' income. For 2001, a large downward revision to wages and
salaries and smaller downward revisions to corporate profits, to farm proprietors' income, and to nonfarm
proprietors' income were partly offset by a large upward revision to net interest and a smaller upward
revision to other labor income.
Corporate profits from current production -- profits before tax with inventory valuation and capital
consumption adjustments -- was revised down for all 3 years: $19.4 billion for 1999, $88.3 billion for
2000, and $35.5 billion for 2001. For 1999, profits before tax (PBT) accounted for most of the revision.
For 2000 and 2001, large downward revisions to PBT and smaller downward revisions to the capital
consumption adjustment accounted for the revisions. For 1999, the downward revision was to profits of
both financial and nonfinancial corporations. For 2000 and 2001, profits of nonfinancial corporations
accounted for most of the downward revisions.
Personal income was revised up $9.2 billion, or 0.1 percent, for 1999; was revised up $87.4 billion,
or 1.1 percent, for 2000; and was revised down $38.2 billion, or 0.4 percent, for 2001. For 1999,
upward revisions to personal interest income, to nonfarm proprietors' income, and to rental income of
persons were partly offset by a downward revision to personal dividend income. For 2000, a large
upward revision to personal interest income and smaller upward revisions to other labor income, to
nonfarm proprietors' income, and to rental income of persons were partly offset by downward revisions
to farm proprietors' income and to personal dividend income. For 2001, a large downward revision to
wage and salary disbursements and smaller downward revisions to farm proprietors' income, to personal
dividend income, and to nonfarm proprietors' income were partly offset by a large upward revision to
personal interest income and smaller upward revisions to transfer payments to persons and to other labor
income. The large downward revision to wage and salary disbursements for 2001 reflected the
incorporation of newly available Bureau of Labor Statistics (BLS) tabulations of wages and salaries of
employees covered by state unemployment insurance.
Disposable personal income (DPI) (personal income less personal tax and nontax payments) was
revised up $9.4 billion for 1999, was revised up $89.2 billion for 2000, and was revised down $24.1
billion for 2001. For 1999 and 2000, the revisions were similar to those to personal income. For 2001, a
downward revision to personal tax and nontax payments also contributed to the revision. The percent
change from the preceding year in real DPI was revised up from 2.5 percent to 2.6 percent for 1999, was
revised up from 3.5 percent to 4.8 percent for 2000, and was revised down from 3.6 percent to 1.8
percent for 2001.
Personal outlays was revised down for all 3 years. Downward revisions to PCE accounted for most
of the revisions for 1999 and 2000 and more than accounted for the revision for 2001. The personal
saving rate (personal saving as a percentage of DPI) was revised up from 2.4 percent to 2.6 percent for
1999, was revised up from 1.0 percent to 2.8 percent for 2000, and was revised up from 1.6 percent to
2.3 percent for 2001.
The statistical discrepancy is current-dollar GDP less current-dollar gross domestic income (GDI).
It arises because most components of GDP and of GDI are estimated independently. GDP measures final
expenditures -- the sum of consumer spending, private investment, net exports, and government
spending. GDI measures the incomes earned in the production of GDP. In concept, GDP is equal to
GDI. In practice, they differ because they are estimated using less than perfectly consistent source data.
As a result of the annual revision, the statistical discrepancy as a percentage of GDP was revised
from -0.8 percent to -0.4 percent for 1999, was revised less than 0.1 percentage point at
-1.3 percent for 2000, and was revised from -1.5 percent to -1.2 percent for 2001. The revision to the
discrepancy for 1999 primarily reflected a downward revision to GDI. For 2000 and 2001, downward
revisions to GDI were partly offset by downward revisions to GDP.
Comment by Doug Henwood:
Well the numbers are out, and the boom was less boomy than we
thought. The last couple of paragraphs deal with the arcane matter of the statistical
discrepancy, which I normally wouldn't bring up, except that in this
case it embarrasses Alan Greenspan. The full name of the GDP exercise
is the national income and product accounts (NIPAs). There are two
sets of estimates - one of product (expenditures on consumption,
investment, etc.) and one of incomes (wages, profits, etc.). In
theory, the two accounts are supposed to match; every dollar of
income is earned in production. In practice, they don't quite match,
and the difference is called the statistical discrepancy. The
statistical discrepancy had been unusually large in the last few
years, for reasons no one quite understood; income was running well
ahead of product. The BEA says the product number is more reliable,
and they feature it in their statistical releases (e.g., many people
have heard of GDP [gross domestic product], but almost no one has
heard of GDI [gross domestic income]). But New Economy optimists,
chief among them Greenspan, focused on the income figure, saying that
it might be the more reliable number. They were wrong. The income
numbers have been revised down significantly, and the statistical
discrepancy has returned to more normal levels. But since Greenspan
is the greatest central banker of all time, this bit of irrational
exuberance won't be held against him.
