Abstract

In countries characterized by large territorial differences in prices and quality of products and household characteristics, calculation of sub-national purchasing power parities (PPPs) can improve and serve as inputs for regular compilation of major indicators as spatial price indexes, real per capita expenditure adjusted for price level differences across regions and estimates of inequality and poverty produced by countries. The main objective of this talk is to provide an overview of the current status of compilation of  sub-national PPPs and to discuss the future of regional price comparisons with increased availability of price data from non-conventional sources such as scanner data recorded at the point of sale and the opportunities and challenges posed by the availability of big data for the regular compilation and dissemination of spatial price comparisons across regions within countries.
