Definition
Price Level refers to the average of current prices across the entire spectrum of goods and services produced in the economy. It’s an important economic indicator used to gauge the overall stability of an economy by comparing it with previous periods. It reflects changes in the purchasing power of money and is key in measuring inflation or deflation.
Examples
-
Consumer Price Index (CPI): The CPI is a widely used means of determining the price level. It measures changes in the price level of a market basket of consumer goods and services purchased by households.
-
Producer Price Index (PPI): The PPI measures average changes in prices received by domestic producers for their output, which can also indicate changes in price levels for goods and services.
-
Historical Comparison: Comparing the price levels of groceries, housing, and other goods in 2022 with those in 1990 to understand how inflation has affected the economy.
