1. While CPI does not represent all the goods which are produced in a country, GDP deflator takes into account all such goods and services.

2. While CPI does not include prices of imported goods, GDP deflator includes prices of imported goods.

3. While the weights are constant in CPI, they differ according to production level of each good in GDP deflator.

Select the correct answer using the code given below.

Explanation:

ANSWER: (C) 

Consumer Price Index (CPI)

  • Consumer Price Index is an index measuring retail inflation in the economy by collecting the change in prices of most common goods and services used by consumers. 
  • Figures of CPI-based inflation are issued every month in India. 

What is the GDP deflator?

  • The GDP deflator, also called implicit price deflator, is a measure of inflation. 
  • It is the ratio of the value of goods and services an economy produces in a particular year at current prices to that of prices that prevailed during the base year.
  • This ratio helps to show the extent to which the increase in gross domestic product has happened on account of higher prices rather than increase in output.
  • Since the deflator covers the entire range of goods and services produced in the economy — as against the limited commodity baskets for the wholesale or consumer price indices — it is seen as a more comprehensive measure of inflation.

Statement 1 is correct.

  • The goods purchased by consumers do not represent all the goods which are produced in a country. GDP deflator takes into account all such goods and services.

Statement 2 is not correct.

  • CPI includes prices of goods consumed by the representative consumer, hence it includes prices of imported goods. GDP deflator does not include prices of imported goods.

Statement 3 is correct.

  • The weights are constant in CPI – but they differ according to production level of each good in GDP deflator.
