Inflation measurement refers to the process of assessing the rate at which the general level of prices for goods and services rises, leading to a decrease in purchasing power. The most common method for measuring inflation is through the Consumer Price Index (CPI), which tracks the prices of a basket of consumer goods and services over time. Another important measure is the Producer Price Index (PPI), which focuses on the prices that producers receive for their products. Both indices help economists, policymakers, and businesses understand economic trends and make informed decisions regarding monetary policy and pricing strategies.
