Three Measurements Of The Welfare Effect Of A Price Change

Although inflation is much feared for its negative effects on the economy, how to measure it is a matter of considerable debate that has important implications for interest rates, monetary supply, and investment and spending decisions. Underlying many of these issues is the concept of the Cost-of-Living Index (COLI) and its controversial role as the methodological foundation for the Consumer Price Index (CPI). Price Index Concepts and Measurements brings together leading experts to address the many questions involved in conceptualizing and measuring inflation. They evaluate the accuracy of COLI, a Cost-of-Goods Index, and a variety of other methodological frameworks as the bases for consumer price construction.

Calls for a more people-focused approach to statistics on economic performance, and concerns about inequality, environmental impacts, and effects of digitalization have put welfare at the top of the measurement agenda. This paper argues that economic welfare is a narrower concept than well-being. The new focus implies a need to prioritize filling data gaps involving the economic welfare indicators of the System of National Accounts 2008 (SNA) and improving their quality, including the quality of the consumption price indexes. Development of distributional indicators of income, consumption, and wealth should also be a priority. Definitions and assumptions can have big effects on these indicators and should be documented. Concerns have also arisen over potentially overlooked welfare growth from the emergence of the digital economy. However, the concern that free online platforms are missing from nominal GDP is incorrect. Also, many of the welfare effects of digitalization require complementary indicators, either because they are conceptually outside the boundary of GDP or impossible to quantify without making uncertain assumptions.

This book provides a general framework for the use of theoretical contributions in empirical works, addressing the question of what is the effect of a price change on household well-being. This simple question is one of the most relevant and controversial questions in microeconomic theory and one of the main sources of errors in empirical economics. In particular, this book aims to 1) Review the essential microeconomics literature since the first seminal papers by Hicks in the 1930s; 2) Organize and simplify this literature in a way that can be easily used by analysts with different backgrounds providing algebraic, geometric and computational illustrations; 3) identify and measure the essential differences across methods and test how these differences affect empirical results; 4) Provide guidelines for the use of alternative approaches under imperfect information on utility, demand systems, elasticities and more generally incomes and quantities; 5) Provide computational codes in Stata for the application of all methods. The focus of the book is on developing economies and the poor, and the assumptions made will relate primarily to these countries and group of people, presumably the main policy focus of international organizations and national governments.

First published in 1981, Professor Mishan’s Economic Efficiency and Social Welfare: Selected Essays on Fundamental Aspects of the Economic Theory of Social Welfare is a collection of 22 pioneering essays written while the author was teaching at the London School of Economics and chosen to indicate landmarks in the development of his own thought. Professor Mishan, who also enjoys an international reputation as a popular writer on the impact of modern economic growth on social welfare, is among the foremost authorities in the field of resource allocation, and his influence in his subject area has been profound. Mishan’s essays, while generally accessible to the layman due to the author’s lucidity, his economy in the use of mathematical notation and his concern with perspective, are invaluable reading for the economics undergraduate. The essays are particularly relevant to upper level students of project appraisal, welfare economics and cost benefit analysis requiring a coherent survey of their field of study.

In September 2001, staff from the World Bank and the International Monetary Fund met with the objective of strengthening collaboration between the two organizations in projects of civil service reform. This strengthened collaboration will have key benefits in ensuring consistency between the conflicting goals of the two organizations, establishing realistic objectives within the reform process, and maintaining a core set of wage and employment data. The principal conclusion arrived at was that World Bank and IMF staff should be engaging in collaboration earlier in the reform process. To guide the collaboration, six foundations were identified. These include: develop a medium-term fiscal framework; foster national ownership by making reforms politically feasible; focus and streamline conditionality; agree on sequencing and timing of reforms; and strengthen data collection. These principals will be tested for effectiveness in several focus countries.

This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest income quintiles with the view to assess the distributional impact of the pass-through. To undertake this analysis, the paper provides an update to the Global Monthly Retail Fuel Price Database, expanding the product coverage to premium and regular fuels, the time dimension to December 2020, and the sample to 190 countries. Three key findings stand out. First, the response of inflation to gasoline price shocks is smaller, but more persistent and broad-based in developing economies than in advanced economies. Second, we show that past studies using crude oil prices instead of retail fuel prices to estimate the pass-through to inflation significantly underestimate it. Third, while the purchasing power of all households declines as fuel prices increase, the distributional impact is progressive. But the progressivity phases out within 6 months after the shock in advanced economies, whereas it persists beyond a year in developing countries.

In an economy characterized by frequent change in technology, in the types of goods and services purchased, and in the forms of business organization, keeping track of price change continues to pose many difficulties. Price change affects the way we perceive changes in such basic measures as real output, productivity, and living standards. This volume, which brings together academic economists with those responsible for official price indexes, presents outstanding new research on price measurement. Half of the papers focus on prices for mainframe and personal computers, semiconductors, and other high-tech products, using mainly hedonic techniques. The volume includes a panel discussion by distinguished economists about the theoretical and practical considerations of how best to measure price change of capital goods whose quality is changing rapidly. The authors also present new research on more conventional but still unsettled problems in the price field affecting both the consumer and producer price indexes of the Bureau of Labor Statistics.

Equity is an abstract concept covering philosophical issues such as fairness and social justice, making its definition and measurement complex. This volume tackles these complexities head-on. The book is enriched with many empirical analyses and provides a comprehensive analysis of equity ranging from concepts and measurements to empirical illustrations and policy implications. After an extensive discussion on equity in the introduction, this volume begins with a chapter on well-being where the concepts of functioning and capability are discussed. This is followed by a few chapters on what an equitable distribution is and how equity can be measured. The volume then provides a definition and a methodology to measure equitable growth, examining the relationship between growth, inequality, and poverty. It also presents various empirical illustrations and country-specific experiences with three country case studies which assess whether publicly provided health and education services are equitable in developing Asia, examining the extent to which these social services favor the poor as well as the policy challenges to a more equitable delivery of these services. Finally, these country studies provide evidence–based policy recommendations to improve equity in social service delivery in developing countries. Achieving social equity has long been an important policy goal. There are relatively few studies on equity. This book aims to help fill this gap with an in-depth analysis of the issues associated with equity, covering its concept, measurement, and policy practices and implications.
