inflation rate

Explanation:

The inflation rate is defined as the rise in the general price level during a certain time period, usually one year. it is usually calculated using the consumer price index (CPI) which measures the weighted average price of a basket of goods.

Many economists try to explain why inflation occurs, and the answers generally vary depending on the school of economics that they follow, but most agree that inflation is the result from an increase in the money supply that makes aggregate demand grow more than aggregate supply. The reasons behind the increase in the money supply are the questionable issues in this case.
