Distinguish nominal and real GDP, calculate real GDP and the GDP deflator, and use base-year prices to compare output over time.
The table provided shows the quantities and unit prices of shirts, bread, and pants, the only
three goods produced in the country of Middleland in 2021 and 2022. Assume that 2021 was the
base year.

Was the real GDP in 2021 in Middleland greater than, less than, or equal to the nominal GDP
in 2021? Explain.
Point 1: The real GDP in 2021 was equal to the nominal GDP in 2021 because 2021 is the base year, no price level changes have occurred, and real values always equal nominal values in the base year.
Calculate the real GDP in Middleland in 2022. Show your work.
Point 2: The real GDP in Middleland in 2022 is $1,190.
Real GDP = ($11 x 50) + ($4 x 70) + ($12 x 30) = $1,190.
