Book Description
A common approach to measuring price changes is to look at the change of the expenditure needed to purchase a fixed basket of goods. It is well-known that this approach suffers from problems and creates several biases in the measurement of price changes faced by consumers. Substitution and outlet bias, two commonly studied concerns, are both driven by consumer choices of what and where to buy. However, consumers also make other choices, including how much and when to buy. We discuss the implications of consumers' timing and quantity decisions have on standard practices of computing of computing a price index. We use household-level data on quantities purchased and prices paid to construct a measure of the savings made by consumers' optimizing behaviour in the purchase of food. In particular, we compare the prices actually paid by the consumers to various alternatives that do not allow for substitution. Our analysis suggests that the average consumer makes significant, and comparable in magnitude, savings from the four dimensions of choice that we study. Furthermore, our data suggests significant heterogeneity in consumer behavior, and that this behavior is correlated with demographics. Our findings suggest that ignoring timing and quantity decisions, when computing a price index, can generate biases on the order of magnitude of substitution and outlet biases.

Book Description
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.

Book Description
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.

Book Description
What is Consumer Price Index According to the Consumer Price Index (CPI), which is a type of price index, the price of a market basket of consumer goods and services that are purchased by households is the price of the market basket. The Consumer Price Index (CPI) is a statistic that tracks changes in prices over time. A representative basket of products and services is utilized in the calculation of the Consumer Price Index (CPI). In order to take into account the shifting patterns of consumer purchasing, the basket is updated on a regular basis. A representative sample of retail and service companies is contacted on a monthly basis to get the pricing of the items and services that are included in the basket. When there is a change in the quality or features, the prices are then modified accordingly. The changes in the Consumer Price Index (CPI) may be utilized to monitor inflation over a period of time and to compare the rates of inflation in other nations. Despite the fact that the Consumer Price Index (CPI) is not an ideal estimator of inflation or the cost of living, it is a helpful instrument for monitoring key economic variables.
