The consumer price index (CPI) measures the rate at which prices of consumer goods and services change over time. It is used as a key indicator of economic performance, as well as in the setting of monetary and socio-economic policy such as indexation of wages and social security benefits, purchasing power parities and inflation measures. This manual contains methodological guidelines for statistical offices and other agencies responsible for constructing and calculating CPIs, and also examines underlying economic and statistical concepts involved. Topics covered include: expenditure weights, sampling, price collection, quality adjustment, sampling, price indices calculations, errors and bias, organisation and management, dissemination, index number theory, durables and user costs.

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.

It has become trite to observe that increases in health care costs have become unsustainable. How best for policy to address these increases, however, depends in part on the degree to which they represent increases in the real quantity of medical services as opposed to increased unit prices of existing services. And an even more fundamental question is the degree to which the increased spending actually has purchased improved health. Accounting for Health and Health Care addresses both these issues. The government agencies responsible for measuring unit prices for medical services have taken steps in recent years that have greatly improved the accuracy of those measures. Nonetheless, this book has several recommendations aimed at further improving the price indices.

This is the first comprehensive study in the context of EMDEs that covers, in one consistent framework, the evolution and global and domestic drivers of inflation, the role of expectations, exchange rate pass-through and policy implications. In addition, the report analyzes inflation and monetary policy related challenges in LICs. The report documents three major findings: In First, EMDE disinflation over the past four decades was to a significant degree a result of favorable external developments, pointing to the risk of rising EMDE inflation if global inflation were to increase. In particular, the decline in EMDE inflation has been supported by broad-based global disinflation amid rapid international trade and financial integration and the disruption caused by the global financial crisis. While domestic factors continue to be the main drivers of short-term movements in EMDE inflation, the role of global factors has risen by one-half between the 1970s and the 2000s. On average, global shocks, especially oil price swings and global demand shocks have accounted for more than one-quarter of domestic inflation variatio--and more in countries with stronger global linkages and greater reliance on commodity imports. In LICs, global food and energy price shocks accounted for another 12 percent of core inflation variatio--half more than in advanced economies and one-fifth more than in non-LIC EMDEs. Second, inflation expectations continue to be less well-anchored in EMDEs than in advanced economies, although a move to inflation targeting and better fiscal frameworks has helped strengthen monetary policy credibility. Lower monetary policy credibility and exchange rate flexibility have also been associated with higher pass-through of exchange rate shocks into domestic inflation in the event of global shocks, which have accounted for half of EMDE exchange rate variation. Third, in part because of poorly anchored inflation expectations, the transmission of global commodity price shocks to domestic LIC inflation (combined with unintended consequences of other government policies) can have material implications for poverty: the global food price spikes in 2010-11 tipped roughly 8 million people into poverty.
