Measuring Inflation and Inflation Expectations

Study Notes

Measuring Inflation

Inflation, the rate at which the general level of prices for goods and services is rising, is a critical economic indicator. Measuring inflation accurately is crucial for policymakers, investors, and consumers to make informed decisions. The most commonly used measures of inflation are the Consumer Price Index (CPI) and the Wholesale Price Index (WPI).

Consumer Price Index (CPI)

The CPI, produced by the Bureau of Labor Statistics, is designed to measure the price changes faced by urban consumers, who represent 93% of the U.S. population. It is an average measure and doesn't reflect any particular consumer's experience. The CPI is constructed each month using 80,000 items in a fixed basket of goods and services representing what Americans buy. Different prices are weighted according to how important they are to the average consumer. For instance, Americans spend more on chicken than tofu, so changes in the price of chicken have a greater impact on the CPI.

Wholesale Price Index (WPI)

The WPI measures the changes in prices of goods and services before they reach the consumer. It is particularly useful for understanding the cost pressures faced by manufacturers and retailers. The WPI is a good indicator of inflationary pressures in the economy. It is calculated by comparing the prices of a fixed basket of goods and services over time.

Inflation Expectations

Inflation expectations play a vital role in influencing inflation. They reflect the average change in prices that consumers and businesses expect to occur in the future. When inflation expectations are well-anchored, they can provide policymakers with a stable baseline from which to assess current and future inflation rates. Central bankers focus on inflation expectations to determine their response to economic shocks. For example, in the context of the Federal Reserve's dual mandate of price stability and maximum employment, a well-anchored inflation expectation can help policymakers better manage aggregate demand.

Surveys of Consumers and Businesses

Inflation expectations are measured through surveys of consumers and businesses. The University of Michigan's Survey Research Center, for instance, asks a sample of households about how much they expect prices to change over the next year and for the next five to ten years. The Federal Reserve Bank of New York and the Conference Board also field similar surveys.

Economists' Forecasts

Economists and financial market participants also contribute to measuring inflation expectations. They compile forecasts based on their analysis of current economic conditions and market trends. These forecasts can provide valuable insights into investors' expectations of future inflation rates.

Inflation-related financial instruments, such as inflation-linked bonds, can also serve as indicators of inflation expectations. The prices of these bonds are directly linked to inflation, and their yields reflect market expectations of future inflation rates.

In conclusion, measuring inflation expectations is essential for understanding and managing inflation. By tracking these expectations, policymakers, investors, and consumers can better anticipate and respond to changes in the broader economic environment.
