1-)
2-)Production Price Index
3-)Inflation Rate
Consumer price index (CPI) measures the price change of a particular bundle of goods from different time periods. It can be calculated as the ratio of cost of the basket in the given year and the cost of the basket in the base year.
CPI = (cost of the basket in the given year/cost of the basket in the base year) * 100%
CPI of a base year will always be equal to 100%.
The Production Price Index (PPI) is a program that will measure the average change in selling price over a time period that is received by domestic producers for selling their product. The price included in the Production Price Index is from the initial commercial transaction for many goods and some services.
The Production Price Index is different from the Consumer Price Index in that it measures costs from the viewpoint of all the industries that make the goods whereas the CPI will measure the prices from the consumer's perspective.
