Producer Price Index (PPI) vs Consumer Price Index (CPI)
Producer Price Index (PPI) and Consumer Price Index (CPI) are related concepts in AP Economics that students often mix up. In short: producer price index (ppi) is the producer price index measures the average change over time in the selling prices that domestic producers receive for their output. Meanwhile, consumer price index (cpi) is cPI is a measure of inflation. Here is how they compare side by side.
The producer price index measures the average change over time in the selling prices that domestic producers receive for their output.
Unlike the CPI, which tracks prices consumers pay, the PPI tracks prices at the wholesale/producer level. Because input costs feed into final prices, PPI changes can be an early signal of future consumer inflation.
CPI is a measure of inflation.
The Consumer Price Index (CPI) is a statistical measure that tracks the weighted average of prices of a basket of goods and services consumed by households. It is used to measure inflation, which is a sustained increase in the general price level of goods and services in an economy. The CPI is calculated by comparing the current prices of the basket of goods and services to a base period. This helps to determine the percentage change in prices over time.
