# GDP Deflator

The GDP deflator is an economic indicator used to measure the changes in prices of goods and services in an economy. It is calculated by dividing the nominal GDP by the real GDP and then multiplying by 100. The GDP deflator is used to compare the value of goods and services produced in different years, as it takes into account the effects of inflation. It is also used to compare the value of goods and services produced in different countries, as it takes into account the effects of exchange rates.

## History of the GDP Deflator

The GDP deflator was first developed by the economist Irving Fisher in the early 20th century. Fisher was looking for a way to measure the changes in the purchasing power of money over time. He proposed the idea of a deflator, which would measure the changes in the prices of goods and services in an economy. The GDP deflator was later adopted by the United Nations in the 1950s as a way to compare the value of goods and services produced in different countries.
