- Statement 1 is incorrect. The GDP deflator is a price index that reflects the prices of all domestically produced goods and services in GDP. It does not use an unchanging basket of commodities; the basket of goods and services included in the GDP changes year to year based on production patterns. This contrasts with indices like the Consumer Price Index (CPI), which uses a fixed basket. - Statement 2 is incorrect. The GDP deflator is indeed used to calculate Real GDP from Nominal GDP (Real GDP = Nominal GDP / GDP Deflator 100). However, it is also commonly used as a measure of the economy's overall inflation rate. Inflation rate between two periods can be calculated from the percentage change in the GDP deflator.
