Table 1 shows economic data for the country of Gondor in the year 2021.
| Consumption | $32bn |
| Investment | $42bn |
| Government Spending | $79bn |
| Exports | $12bn |
| Imports | $16bn |
| Income from abroad | $3bn |
| Income sent abroad | $6bn |
Question 1
Using the data from table 1 calculate the GDP for Gondor in 2021 using the expenditure approach
To calculate GDP using the expenditure approach students should use the following formula.
GDP = C + I + G + ( X − M)
Where:
C = Consumer spending
I= Investment
G= Government spending
X= Exports
M= Imports
Thus:
Gondor’s GDP (2021) = 32 + 42 + 79 + (12 – 16) = $149bn
Question 2
Using the data from table 1 calculate the GNI for Gondor in 2021
To calculate GNI students should use the following formula.
GNI = GDP + Net Income from Abroad
Thus:
Gondor’s GNI (2021) = 149 + 3 – 6 = $146bn
Table 2 shows the nominal GDP and GDP deflator for the country of Gondor for the years 2017 to 2020. The base year is 2017.
| Year | Nominal GDP ($ billion) | GDP Deflator | Real GDP ($ billion) |
| 2017 | 135 | 100 | |
| 2018 | 142 | 103.25 | |
| 2019 | 140 | 104.10 | |
| 2020 | 146 | 106.50 |
Question 3
Using the data from table 2 calculate the real GDP for Gondor in each year.
To calculate real GDP students should use the following formula.
Real GDP = Nominal GDP / GDP Deflator * 100
Thus:
Gondor’s Real GDP (2020) = 146 / 106.50 * 100 = $137.09bn
| Year | Nominal GDP ($ billion) | GDP Deflator | Real GDP ($ billion) |
| 2017 | 135 | 100 | 135 |
| 2018 | 142 | 103.25 | 137.53 |
| 2019 | 140 | 104.10 | 134.49 |
| 2020 | 146 | 106.50 | 137.09 |
Question 4
Using the data from table 2 calculate Gondor’s real annual growth rate for the years 2018, 2019 and 2020.
To calculate the real annual growth rate students should use the following formula.
% Change in Real GDP = (Real GDP Y1 – Real GDP Y2) / Real GDP Y2 * 100
Thus:
Gondor’s Real Annual Growth Rate (2018) = (137.53 – 135) / 135 * 100 = 1.87%
Gondor’s Real Annual Growth Rate (2019) = (134.49 – 137.53) / 137.53 * 100 = -2.21%
Gondor’s Real Annual Growth Rate (2020) = (137.09 – 134.49) / 134.49 * 100 = 1.93%
Question 5
Using the data from table 2 in which year(s) did Gondor experience a recession?
Based on the data from table 2 it is reasonable to assume that Gondor experienced a recession during the year of 2019. This is because Gondor’s nominal and real GDP was lower in 2019 than in 2018. In addition, in 2019 Gondor experienced a negative real annual growth rate of -2.21%.
Question 6
In 2019 Gondor was at war with the land of Mordor. The war reduced Gondor’s population from 30 million in 2018 to 29.8 million in 2019. Based on this information and the data in table 2, calculate Gondor’s real GDP per capita for the years 2018 and 2019.
To calculate real GDP per capita students should use the following formula.
Real GDP Per Capita = Real GDP / Size of Population
Thus:
Gondor’s Real GDP Per Capita (2018) = (137.53 * 10^9) / (30 * 10^6) = $4584.33
Gondor’s Real GDP Per Capita (2019) = (134.49 * 10^9) / (29.8 * 10^6) = $4513.09
Question 7
Suppose that during 2020-2021 Gondor’s real GDP grew by 3% and the population grew by 5%. Based on this information, by how much did real GDP per capita grow in 2020-2021?
To calculate the change in real GDP per capita students should use the following formula.
% Change in Real GDP Per Capita = % Change in Real GDP – % Change in Population
Thus:
Gondor’s Change in Real GDP Per Capita (2020-2021) = 3% – 5% = -2%
