Mar. 21 - <snip>A growing number of discrepancies are emerging in America's economic numbers, including a dramatic over-estimation of manufacturing output. The latest analysis from Goldman Sachs suggests that the US economy may have grown by only about 2.2 percent in the year to the fourth quarter of 2003, considerably less than the official 4.3 percent.<snip>
Hatzius (senior economist at Goldman Sachs) said: "Over the last year, the official data show real gross domestic product (GDP) growing a sturdy 4.3 percent. Yet, non-farm payrolls are up only 0.1 percent. It is hard to overemphasise how unusual this combination is."
The results of the alternative, survey-based method have also been weak, recording a 1.5 percent rise in household employment since November 2001, the smallest gain of any post-war business cycle, despite the dramatic rebound in US economic growth on the official figures.
Big flaws in the manufacturing data are responsible, according to the Goldman research. Real GDP for goods, which accounts for 33 percent of total GDP, has surged by 8 percent over the past year, the official figures say, more than double its 3.6 percent long-term trend. But these figures are in complete contradiction with the standard data for industrial production (increased by only 1.4 percent), a closely-related and far more reliable measure calculated using separate data.<snip>
Real GDP for services and structures, which together account for the remaining 67 percent of GDP, rose only 2.6 percent, below their 3.4 percent long-term trend. It is unusual to see goods output surging at a time when growth in the other GDP components is lacklustre, suggesting flaws in the official estimates.<snip>
Another reason why the US official growth rate may have over-stated growth is because of its use of "hedonic pricing", a method which adjusts inflation for quality, other economists say.<snip>
Comparisons between growth in the US and the UK are also complicated by differences in accounting. "In particular, the use of hedonic pricing in measuring the value-added provided by the US high-tech sector gives a substantial boost to US output compared to that in the UK," says the London Business School's Economic Outlook.
