Nominal GDP and Real GDP
The GDP calculation is distorted by inflation. This unadjusted GDP is known as the nominal
GDP.
In practice, GDP is adjusted by dividing the nominal GDP by a price deflator to arrive at the real
GDP.
· GDP usually is reported each quarter on a seasonally adjusted annualized basis
In an inflationary environment, the nominal GDP is greater than the real GDP.
If the price deflator is not known, an implicit price deflator can be calculated by dividing the
nominal GDP by the real GDP:
· Implicit Price Deflator = Nominal GDP / Real GDP
The composition of this deflator is different from that of the consumer price index in that the
GDP deflator includes government goods, investment goods, and exports rather than the
traditional consumer-oriented basket of goods.
