摘要：The International Comparisons Program (ICP) compares the purchasing power of currencies
through a series of regional comparisons that are then linked together to obtain
results at the global level. This process of regionalization complicates the construction
of price indexes by essentially forcing the adoption of a two-stage approach. In previous
rounds of ICP, data constraints have largely determined how the regions are linked.
These data constraints, however, are largely absent in ICP 2005. This raises the question
of how best to extend existing price index formulas to cope with the regionalization
process that underpins ICP 2005. This paper attempts to answer this question, while at
the same time imposing some structure on the existing literature on two-stage methods.
