Question 19

Basket of goods and services

The Consumer Price Index (CPI) primarily measures the average change over time in the prices paid by urban consumers for a basket of goods and services. This includes categories like food, housing, clothing, transportation, and medical care.

A) Basket of goods and services

This option is correct as the CPI is specifically designed to track the price changes of a predefined set of goods and services that are representative of typical consumer spending. By measuring these price changes, the CPI provides a clear indication of inflation and purchasing power over time.

B) Tax fluctuations

This option is incorrect because tax fluctuations are not directly measured by the CPI. While taxes can influence consumer prices indirectly, the CPI focuses exclusively on the prices of goods and services rather than taxation levels or changes.

C) Stocks and bonds

This option is also incorrect. The CPI does not include financial assets such as stocks and bonds in its measurement. The index is concerned only with consumer goods and services, which do not encompass the performance of financial markets.

D) Wage changes

This option is incorrect as well. Although wage changes may affect consumer purchasing power, they are not part of the CPI measurement. The CPI is strictly about the price level of goods and services and does not account for income or wage data.

Conclusion

The correct answer is the basket of goods and services, as it is the fundamental component of how the CPI is calculated and what it represents. Other options, such as tax fluctuations, stocks and bonds, and wage changes, do not fit within the scope of the CPI's focus on consumer prices, making them incorrect choices.
