Definition
A market basket refers to a specific collection of goods and services that are selected to represent the consumption patterns of a typical consumer or business. This assortment of items is used primarily to track and measure changes in price levels over time. These price changes are essential for calculating vital economic indicators, such as the Consumer Price Index (CPI) and the Producer Price Index (PPI).
Examples
Example 1: Consumer Price Index (CPI)
The CPI utilizes a market basket composed of items frequently purchased by households, including food, clothing, healthcare, and transportation. By comparing the cost of this basket over different periods, economists can determine inflation rates affecting consumers.
Example 2: Producer Price Index (PPI)
In contrast, the PPI market basket focuses on goods and services bought by producers rather than consumers. This might include raw materials like steel, machinery, and transportation services. The PPI helps gauge the inflationary pressures in the production process.
