World Economics, March 2011
Price indexes are the most important of all economic indicators simply because they are the tool used to calculate the real size, speed and direction of all forms of economic activity. Price indexes are compiled almost everywhere, but with major differences in method and sampling procedures. Some methods and procedures have led to significant errors. Even in the case of a country as advanced as Japan, critics have calculated that imperfections in method have led to a rate of price inflation around 1.8% per year above the level a true cost of living index would have shown. Further research undertaken by World Economics has attempted to make estimates for changes in discounting and promotional practices at the retail level. The conclusion is that, in reality, the overestimation of price changes by the Japanese CPI in recent years may well have been in excess of 2% per annum, and could have been significantly more. Different CPI assumptions change economic growth estimates dramatically. Using World Economics estimates, adding in a minimum figure for marketing and retail changes seen in recent years suggests, contrary to official data, that Japanese consumption growth exceeded that of the US.

Angus Maddison and Harry Wu (2008) claim that, in 2003, China’s GDP was 73% of that of the United States on a purchasing power parity (PPP) basis. Rejecting the results of the 2005 International Comparison Program (ICP), they construct their own PPP using a 1986 GDP estimate for China (Ren & Chen 1995) which they adjust upwards, and then extrapolate to 2003 using their revised growth rates for China, which they adjust downwards. This note examines the validity of their adjustments and assumptions, and finds them to be inconsistent with recommendations both from the perspective of index number theory and recommended national accounting practices. The 2005 PPP estimates from the ICP, which Maddison and Wu reject, produce a more plausible estimate of the size of China’s economy relative to that of the US (43% in 2005).

China is the world’s fastest growing economy and is also the second largest. However, the official estimates of the Chinese National Bureau of Statistics exaggerate GDP growth and need adjustment to conform to international norms as set out in the 1993 System of National Accounts (SNA). This paper presents and discusses the necessary adjustments. The two major contributions are new volume indices for the industrial sector and for "non-material" services. Finally, in order to measure the level of Chinese GDP in internationally comparable terms, the authors use a measure of purchasing power parity (PPP) instead of the exchange rate.
