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...

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...

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...

Purpose – The contribution of this study is both methodological and empirical. It provides a method of estimating preference consistent true cost of living indices and demonstrates the use of unit values (food items), adjusted for quality and demographic effects, as prices. Using NSS data,...

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...

While purchasing power parity (PPP) between countries has received a great deal of attention, PPP calculations within countries have received less attention. The idea that one unit of currency has the same purchasing power in all regions in large countries is false. This paper addresses this...

This study addresses two significant limitations in the literature on cross-country expenditure comparisons: (a) treatment of all countries, large and small, as single entities with no spatial differences inside the countries, and (b) use of Divisia price indices, rather than preference based...

Much of the recent welfare analysis in the development literature has focussed attention on poverty. This is especially true for India which has seen a large proliferation in the poverty literature. This study departs from this tradition and focuses on inequality. It is based on the premise that...

Purpose: This study aims to apply a proposed methodology for calculating spatial prices in a heterogeneous country setting such as India with limited price information. Based on the empirical evidence, the study plans to draw the spatial price map of India with different colours denoting states...

Purpose: The purpose of this study is to examine the sensitivity of regional and world poverty rates to the purchasing power parities (PPP) used in the calculations. The PPPs are required to convert the “international poverty line” typically denominated in US dollar to its local currency...
