Explanation:

Inflation is measured by a central government authority, which is in charge of adopting measures to ensure the smooth running of the economy. In India, the Ministry of Statistics and Programme Implementation measures inflation. The literal meaning of the word inflation is to blow up or get bigger. If the amount of money in a country - the money supply - grows faster than production in that country, the average price will rise as a result of the increased demand for goods and services. Inflation can also be caused by higher costs being charged on to the end-user. These might be raw material costs or production costs which have risen, but could also be higher tax rates. These price rises cause the value of money to fall. You can therefore buy less with the same amount of money. But this does not need to have an immediate effect on purchasing power. Purchasing power only declines if wages rises less rapidly than prices.
