Positions of China and US in the World Economic Space of XXI Century
The article deals with some issues of PPP-based international economic comparisons. Considering the case of two world largest economies - China and USA - the problems of economic size and level of economic development accurate estimation are formulated. In particular, the weak points - which severely limits capacity of the researchers for analysis and forecasting, - of IMF and World Bank methods for PPP-based indicators are indicated. The fact of inability to obtain, at the current quality of statistics, precise estimates of PPP GDPs both for developing (low- and middle-income) and for developed (high-income) countries is stressed. The reasons for revising IMF and World Bank methods of PPP-based GDPs adjustment are given.
