Which statement best defines inflation and the role of the CPI?

• A. Inflation is the rate at which the overall price level rises; the CPI tracks changes in the price of a fixed basket of goods over time.
• B. Inflation is a fall in the price level; the CPI measures unemployment.
• C. Inflation measures government deficit growth; the CPI tracks taxes.
• D. Inflation is only about consumer prices; the CPI tracks producer prices.

Answer: (A)

Inflation is the rate at which the overall price level in the economy rises. It isn’t about the price of just one item, but about the broad upswing in prices across many goods and services that households typically buy. The consumer price index measures changes in the prices of a fixed basket of goods and services that reflect typical consumer spending. By keeping the basket constant and watching how its total cost changes over time, the CPI provides a way to quantify how much prices, on average, have risen. This is why the CPI is used as a practical gauge of inflation and for adjusting incomes and contracts for changes in the cost of living. Keep in mind that the CPI has limitations: it’s based on a fixed basket, so it may not perfectly reflect substitutions consumers make or changes in product quality. Other price measures, like the GDP deflator, capture different aspects of price changes, but the essential idea remains that inflation is about a rising price level, and the CPI tracks that by monitoring the cost of a representative fixed basket of consumer goods.
