Question

Consider an economy that produces only chocolate bars. In year 1, the quantity produced is 3 bars and the price is $2. In year 2, the quantity produced is 5 bars and the price is $4. In year 3, the quantity produced is 7 bars and the price is $6.

Required:
Using year 1 as the base year, compute nominal GDP, real GDP, and the GDP deflator for each year.

Answer 1

Nominal GDP in year 1 = $6

Nominal GDP in year 2 = $20

Nominal GDP in year 3 = $42

Real GDP in year 1 = $6

Real GDP in year 2 = $10

Real GDP in year 3 = $14

GDP deflator in year 1 = 100

GDP deflator in year 2 = 200

GDP deflator in year 3 = 300

Step-by-step explanation:

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export

Nominal GDP is GDP calculated using current year prices while Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.

Nominal GDP = quantity produced x current year price

Nominal GDP in year 1 = (3 x $2) = $6

Nominal GDP in year 2 = 5 x $4 = $20

Nominal GDP in year 3 = 7 x $6 = $42

Real GDP = quantity produced x base year price

Real GDP in year 1 = (3 x $2) = $6

Real GDP in year 2 = 5 x $2 = $10

Real GDP in year 3 = 7 x $2 = $14

GDP deflator = nominal GDP / Real GDP x 100

GDP deflator in year 1 = $6 / $6 x 100 = 100

GDP deflator in year 2 = $20 / $10 x 100= 200

GDP deflator in year 3 = $42 / 14 x 100 = 300
