Review Questions

• Explain how the Consumer Price Index (CPI) is used to measure inflation in the economy.
  • The Consumer Price Index (CPI) is a measure of the average change in prices paid by consumers for a basket of goods and services over time. It is calculated by the Bureau of Labor Statistics (BLS) and is based on a representative sample of consumer expenditures. The CPI is used as a key indicator of inflation, as it tracks the changes in the general price level of consumer goods and services. By monitoring the CPI, policymakers, businesses, and consumers can understand the rate at which the purchasing power of the currency is eroding, allowing them to make informed decisions about wages, prices, and monetary policy.
• Describe the relationship between the Consumer Price Index (CPI) and the Federal Reserve's monetary policy decisions.
  • The Consumer Price Index (CPI) is a crucial economic indicator that the Federal Reserve closely monitors when making monetary policy decisions. The Federal Reserve's primary mandate is to maintain price stability and full employment, and the CPI is a key measure of inflationary pressures in the economy. When the CPI indicates that inflation is rising, the Federal Reserve may choose to raise interest rates to slow down economic activity and bring inflation under control. Conversely, if the CPI suggests that inflation is low or declining, the Federal Reserve may opt to lower interest rates to stimulate the economy and promote growth. By using the CPI as a guide, the Federal Reserve can adjust its monetary policy tools to achieve its dual mandate and maintain a stable economic environment.
• Evaluate the importance of the Consumer Price Index (CPI) as a macroeconomic indicator and its impact on consumer purchasing power and the overall economy.
  • The Consumer Price Index (CPI) is a crucial macroeconomic indicator that has far-reaching implications for both consumers and the broader economy. As a measure of the average change in prices paid by consumers for a basket of goods and services, the CPI directly reflects the purchasing power of the currency and the cost of living. When the CPI rises, it indicates that inflation is eroding the value of the dollar, reducing the real purchasing power of consumers. This can have significant consequences, as it may lead to a decline in consumer confidence, reduced spending, and slower economic growth. Conversely, a stable or declining CPI can signal a healthy economy with low inflationary pressures, allowing consumers to maintain their standard of living and encouraging businesses to invest and expand. Given its importance in assessing the overall economic well-being of a country, the CPI is closely watched by policymakers, economists, and the general public, as it informs critical decisions related to monetary policy, wage adjustments, and government benefit programs.
