Definition
The Personal Consumption Expenditures Price Index (PCEPI) is an important economic measure in the United States. It tracks the average increase in prices for goods and services purchased by households. Unlike other indices, the PCEPI is based on a broader array of data sources, including the Consumer Price Index (CPI) and the Producer Price Index (PPI).
The index is presented in two forms:
- The headline PCEPI includes all items purchased by consumers.
- The core PCE price index excludes food and energy due to their volatile nature.
Indexed to a base of 100 in 2005, the PCEPI is utilized by policymakers, especially the Federal Reserve, to gauge inflation and make critical economic decisions.
Examples
-
Calculating Inflation: If the PCEPI increases from 100 to 105 from one year to the next, this indicates an inflation rate of 5% for that period.
-
Adjusting Wages: Businesses might adjust wages in line with changes in the PCEPI to maintain employees’ purchasing power.
Frequently Asked Questions (FAQs)
Q: What is the base year of the PCEPI?
A: The base year for the PCEPI is 2005.
Q: How does the PCEPI differ from the Consumer Price Index (CPI)?
A: While both indices measure inflation, the PCEPI uses a broader array of data sources than the CPI, providing a more comprehensive view of price changes.
Q: Why does the Federal Reserve prefer the PCEPI over the CPI?
A: The Federal Reserve favors the PCEPI because it offers a broader coverage of personal consumption expenditures and incorporates different weights and adjustments, making it a more consistent measure of inflation.
Q: What is the core PCE price index?
A: The core PCE price index excludes food and energy prices due to their high volatility, offering a more stable measure of inflation.
