Purpose The purpose of this paper is to extend the methodology proposed in Majumder et al. (2012) for the estimation of the item-specific purchasing power parities (PPPs) within countries, to the cross-country context. It estimates item-specific intra-country PPPs (i.e. spatial prices) and...

This paper proposes a preference based methodology, analogous to the estimation of equivalence scales in the demographic demand literature, for the estimation of the item specific intra country PPPs (i.e. spatial prices) and inter country PPPs in a unified framework using unit records of...

This study introduces, for the first time, the concept of item specific purchasing power parity (PPP) between countries that marks a significant departure from exercises such as the International Comparison Program (ICP). The paper proposes a methodology for the estimation of the item specific...

This study departs from the previous literature on purchasing power parity (PPP) by proposing a demand system based methodology for calculating the PPP that takes account of consumer preferences and allows for the substitution effect of price changes. The methodology is applied to provide...
