The consumer price index (CPI), a common measure of inflation, measures the price change over time for a basket of goods and services. The basket is representative of consumer spending patterns, and the change in its price represents the rate of inflation faced by consumers as a whole.For example, if the basket's price has increased 5% in the course of the year, consumer inflation can be said to be running at a 5% annual rate. The definition and contents of the measured basket can vary widely by country.In the U.S., the Bureau of Labor Statistics (BLS) monthly collects the prices of some 94,000 items from a scientifically selected sample of goods and services to assemble its representative basket. The numbers are then adjusted to ensure price changes don't reflect improvements in product quality, and weighted in proportion with consumer spending patterns derived from a separate survey of about 36,000 consumers in a given year.
Definition
A basket of goods refers to a set of products and services used to measure the Consumer Price Index (CPI). These goods and services represent the consumption patterns of a typical consumer, and their price changes are used to calculate the inflation rate.
Origin
The concept of a basket of goods originated from economic studies on inflation. Over time, governments and economists began using baskets of goods to more accurately reflect consumer spending habits and price changes.
Categories and Features
Baskets of goods can be categorized based on different consumer groups and regions. For example, urban and rural areas might have different baskets. Additionally, the goods and services in the basket are regularly updated to reflect changes in consumer preferences. Its features include diversity and representativeness, ensuring it accurately reflects changes in overall market price levels.
Case Studies
In the United States, the Bureau of Labor Statistics (BLS) collects price data from about 94,000 items each month to assemble its representative basket of goods. This basket is adjusted based on the consumption patterns of about 36,000 consumers to ensure that price changes do not reflect improvements in product quality. Another example is Japan's CPI, where the basket of goods is managed by the Statistics Bureau of the Ministry of Internal Affairs and Communications and is updated every five years to reflect the latest consumption trends.
Common Issues
Common issues investors face when using basket of goods data include how to interpret changes in the CPI and how to apply it to investment decisions. A common misconception is equating a rise in the CPI directly with an increase in all product prices, whereas the CPI is a weighted average, and individual product prices may vary differently.
