On the Equivalence of Weighted Country-Product-Dummy (Cpd) Method and the Rao-System for Multilateral Price Comparisons


Book Description

The country-product-dummy (CPD) method, originally proposed in Summers (1973), has recently been revisited in its weighted formulation to handle a variety of data related situations (Rao and Timmer, 2000, 2003; Heravi et al., 2001; Rao, 2001; Aten and Menezes, 2002; Heston and Aten, 2002; Deaton et al., 2004). The CPD method is also increasingly being used in the context of hedonic modelling instead of its original purpose of filling holes in Summers (1973). However, the CPD method is seen, among practitioners, as a black box due to its regression formulation. The main objective of the paper is to establish equivalence of purchasing power parities and international prices derived from the application of the weighted-CPD method with those arising out of the Rao-system for multilateral comparisons. A major implication of this result is that the weighted-CPD method would then be a natural method of aggregation at all levels of aggregation within the context of international comparisons.




The Hedonic Country Product Dummy Method and Quality Adjustments for Purchasing Power Parity Calculations


Book Description

The 2005 International Comparison Program's (ICP) estimates of economy-wide purchasing power parity (PPP) are based on parity estimates for 155 basic expenditure headings, mainly estimated using country product dummy (CPD) regressions. The estimates are potentially inefficient and open to omitted variable bias for two reasons. First, they use average prices across outlets as the left-hand-side variable. Second, quality-adjusted prices of non-comparable replacements, required when products in outlets do not match the required specifications, cannot be effectively included. This paper provides an analytical framework based on panel data and hedonic CPD regressions for ameliorating these sources of bias and inefficiency.




Measuring the Real Size of the World Economy


Book Description

This volume provides a comprehensive review of the statistical theory and methods underlying the estimation of purchasing power parities (PPPs) and real expenditures, the choices made for the 2005 International Comparison Program (ICP) round, and the lessons learned that led to improvements in the 2011 ICP.




Price and Quantity Index Numbers


Book Description

This book is the first comprehensive text on index number theory since Irving Fisher's 1922 The Making of Index Numbers. The book covers intertemporal and interspatial comparisons; ratio- and difference-type measures; discrete and continuous time environments; and upper- and lower-level indices. Guided by economic insights, this book develops the instrumental or axiomatic approach.




Advances in Economic Measurement


Book Description

The purpose of this book is to honour D.S. Prasada Rao and his many outstanding contributions to economic measurement, including index number methods for international comparisons of prices, real incomes, output, and productivity; stochastic approaches to index numbers; purchasing power parities for the measurement of regional and global inequality and poverty; and measurement of income and economic insecurity. This book brings together contributions by well-known and influential researchers in the field of economic measurement with special focus on topics in productivity measurement (Part I); income and health inequality, inequality of opportunity, and measurement of insecurity (Part II); index number theory and applications to consumer price index numbers, international comparisons of prices and real expenditures, and housing price index numbers (Part III). The chapters are authored by eminent researchers including Conchita D’Ambrosio, Bert Balk, Erwin Diewert, Robert Hill, Robert Inklaar, Knox Lovell, Robin Sickles, Jacques Silber and Marcel Timmer. The contributed papers offer in-depth reviews of the state of the art in these areas with a focus on the existing methods and applications, making the volume an invaluable source for both experienced researchers and new researchers, including PhD and other postgraduate students.







Price Indexes in Time and Space


Book Description

This book deals with many of the most relevant topics in price index numbers theory and practice. The problem of the harmonization of CPIs and the time-space integration of baskets is analyzed at the Eu-zone level, with methodological and actual proposals on how to proceed for an overall treatment of the matte. Likewise, the construction of sub-indexes for households economic and social groups is investigated, in order to obtain specific inflation measurement instruments. Evidence from most updated databases is given. The questions of the spatial comparisons of price levels through PPPs and th.

Household Behaviour, Prices, and Welfare


Book Description

This collection of essays covers a diverse set of topics related to household behavior and welfare. Prices play a key role in several of the essays, particularly the distributional implications of price movements, and the effects of changes in relative prices on inequality and poverty. This book shows the shift in the literature on prices from being an exclusively macro topic featuring the study of inflation and cross-country comparisons to one that is firmly rooted in micro theory-based analysis of household behavior. It also includes recent developments in the poverty measurement literature, documenting the shift from the exclusively money metric and unidimensional poverty measures to multidimensional poverty encompassing a wider view of deprivation. Largely, but not exclusively, focusing on India, the book also features global comparisons of welfare. Intra country spatial comparisons along with cross country comparisons of household behavior and welfare feature in several of the essays in this book. The book also compares the effects of selected public delivery schemes in India on the health of its children. It is a useful resource for researchers and serves as reading material for advanced graduate courses on development in India and elsewhere.
