  • 摘要:While national and international statistical agencies spend much resource on calculating purchasing power parity (PPP) between countries, relatively little attention is given to PPP calculations within countries. Yet, for large and heterogeneous countries, such as the US and India, intra country PPP is as important as cross-country PPP. This is particularly true of the rural urban divide in such countries where the idea that one unit of currency has the same purchasing power in both sectors is clearly false. This paper addresses this limitation by proposing a demand system based methodology for calculating rural urban PPP that incorporates rural urban differences in preferences and applies it to India. The methodology is compared with conventional procedures, such as the Laspeyre’s price index and the CPD model, and shown to have several advantages over them. The result on significant rural urban price difference in India underlines the need to extend the cross-country PPP calculations to incorporate spatial differences in large, heterogeneous countries with a diverse set of preferences and prices
