Question 1
Question
Assume the following data for an economy:
Consumption expenditures: 200 billion
Investment expenditures: 100 billion
Government purchases: 50 billion
Exports: 30 billion
Imports: 20 billion
Calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach.
Solution
Step 1: The GDP using the expenditure approach is calculated as the sum
of consumption expenditures, investment expenditures, government purchases,
exports minus imports.
GDP = Consumption + Investment + Government + Net exports
GDP = 200 + 100 + 50 + (30 −20)
Step 2: Calculate the net exports.
Net exports = Exports −Imports = 30 −20 = 10
Step 3: Substitute the values into the formula and calculate the GDP.
GDP = 200 + 100 + 50 + 10 = 360 billion
Therefore, the Gross Domestic Product (GDP) for this economy is 360 bil-
lion.
Question 2
Question
Suppose a country’s Gross Domestic Product (GDP) is calculated using the
expenditure approach, with the following information:
Personal Consumption Expenditures:
$
800 billion
Gross Private Domestic Investment:
$
200 billion
Government Consumption Expenditures and Gross Investment:
$
300 bil-
lion
Net Exports:
$
50 billion
Calculate the country’s GDP using the expenditure approach.
Solution
To calculate the country’s GDP using the expenditure approach, we sum up the
various components: Personal Consumption Expenditures (C), Gross Private
Domestic Investment (I), Government Consumption Expenditures and Gross
Investment (G), and Net Exports (NX).
Step 1: Write down the formula for GDP using the expenditure approach:
GDP =C+I+G+NX
Step 2: Given data:
C= $800 billion
I= $200 billion
G= $300 billion
NX = $50 billion
Step 3: Substitute the given values into the GDP formula:
GDP = $800 billion + $200 billion + $300 billion + $50 billion
Step 4: Simplify the expression by adding the values:
GDP = $1350 billion
Therefore, the country’s GDP using the expenditure approach is
$
1350 bil-
lion.

Question 3
Question
Calculate the Gross Domestic Product (GDP) using the following information
for a fictional country:
Consumption:
$
500 billion
Investment:
$
200 billion
Government spending:
$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Solution
Step 1: Calculate Net Exports
Net Exports = Exports −Imports = $100 billion −$80 billion = $20 billion
Step 2: Calculate GDP
GDP = Consumption + Investment + Government Spending + Net Exports
GDP = $500 billion + $200 billion + $150 billion + $20 billion = $870 billion
Therefore, the Gross Domestic Product (GDP) of the fictional country is
$
870 billion.
Question 4
Question
Suppose a country’s economy produces only three goods: apples, oranges, and
bananas. The quantities produced and the prices for each of these goods in year
1 and year 2 are given in the table below:
Goods Quantity (year 1) Price (year 1) Quantity (year 2)
Price (year 2)
Apples 100 $1 120
$1.50
Oranges 150 $2 200
$2.50
Bananas 80 $0.50 100
$0.75
Calculate the Gross Domestic Product (GDP) for year 1 and year 2 using
both the formula approach and the expenditure approach.
3
Solution
Let’s calculate the Gross Domestic Product (GDP) for year 1 and year 2 using
both the formula approach and the expenditure approach.
Formula Approach: Step 1: Calculate nominal GDP using the formula
approach:
Nominal GDP = X(Price ×Quantity)
For year 1:
Nominal GDP (year 1) = (100×1)+(150×2)+(80×0.5) = 100+300+40 = $440
For year 2:
Nominal GDP (year 2) = (120×1.5)+(200×2.5)+(100×0.75) = 180+500+75 = $755
Step 2: Adjust for inflation using the GDP deflator to calculate real GDP:
GDP Deflator = Nominal GDP
Real GDP ×100
For year 1:
GDP Deflator (year 1) = 440
440×100 = 100
For year 2:
GDP Deflator (year 2) = 755
440×100 ≈171.59
Expenditure Approach: Step 1: Calculate GDP using the expenditure
approach:
GDP = C+I+G+ (X−M)
Where: - C= Household consumption - I= Investment - G= Government
spending - X= Exports - M= Imports
For both years:
C= (100 ×1) + (150 ×2) + (80 ×0.5) + (120 ×1.5) + (200 ×2.5) + (100 ×0.75)
C= 440 + 315 = $755
Therefore, the GDP for year 1 and year 2 using both methods are as follows:
- Nominal GDP (year 1):
$
440, Nominal GDP (year 2):
$
755 - Real GDP (year
1):
$
440, Real GDP (year 2):
$
440 - GDP Deflator (year 1): 100, GDP Deflator
(year 2): 171.59

Question 5
Question
A country’s economy has the following components for a specific year: - Con-
sumption expenditure:
$
800 billion - Investment expenditure:
$
200 billion -
Government expenditure:
$
300 billion - Exports:
$
150 billion - Imports:
$
120
billion
Calculate the Gross Domestic Product (GDP) of the country for that year.
Solution
To calculate the Gross Domestic Product (GDP) of a country, we can use the
formula:
GDP =C+I+G+ (X−M)
where: - Cis the consumption expenditure - Iis the investment expenditure - G
is the government expenditure - Xis the total exports - Mis the total imports
Step 1: Calculate the value of exports minus imports.
X−M= 150 −120 = 30 billion
Step 2: Substitute the given values into the GDP formula and solve for
GDP.
GDP = 800 + 200 + 300 + 30
GDP = 1330 billion
Therefore, the Gross Domestic Product (GDP) of the country for that year
is
$
1.33 trillion.

$
100 billion Calculate the Gross Domestic
Product (GDP) of the country for that year.
Solution
Step 1: The formula for calculating GDP is:
GDP =C+I+G+ (X−M)
where: - Crepresents consumption - Irepresents investment - Grepresents
government spending - Xrepresents exports - Mrepresents imports
5
Step 2: Substitute the given values into the formula:
GDP = 500 + 200 + 300 + (150 −100)
Step 3: Calculate the values:
GDP = 500 + 200 + 300 + 50
Step 4: Add the values to find the GDP:
GDP = 1050
Therefore, the Gross Domestic Product (GDP) of the country for that year
is
$
1050 billion.
Question 7
Question
Calculate the Gross Domestic Product (GDP) using the expenditure approach
given the following information:
Consumption expenditure: 400 billion
Investment expenditure: 150 billion
Government expenditure: 100 billion
Exports: 50 billion
Imports: 30 billion
Solution
Step 1: Calculate the Net Exports.
Net Exports = Exports −Imports
Net Exports = 50 billion −30 billion
Net Exports = 20 billion
Step 2: Calculate the GDP using the expenditure approach.
GDP = Consumption + Investment + Government + Net Exports
GDP = 400 billion + 150 billion + 100 billion + 20 billion
GDP = 670 billion
Therefore, the Gross Domestic Product (GDP) calculated using the expen-
diture approach is 670 billion.

100 billion
Net Exports:
$
50 billion (Exports - Imports)
Calculate the country’s GDP using the expenditure approach.
Solution
Step 1: Calculate the total GDP using the expenditure approach:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 2: Substitute the given values into the formula:
GDP = 500 billion + 150 billion + 100 billion + 50 billion
Step 3: Perform the arithmetic to find the total GDP:
GDP = 800 billion + 50 billion

Question 11
Question
Suppose a country’s GDP is
$
400 billion, consumption is
$
300 billion, govern-
ment expenditure is
$
100 billion, exports are
$
50 billion, and imports are
$
70
billion. Calculate the country’s GDP using the expenditure approach.
Solution
To calculate the country’s GDP using the expenditure approach, we sum up
all the components: consumption (C), government expenditure (G), investment
(I), exports (X), and subtract imports (M). The formula is:
GDP =C+G+I+ (X−M)
Given:
C= $300 billion
G= $100 billion
X= $50 billion
M= $70 billion
Step 1: Calculate Net Exports
X−M= $50 −$70 = −$20 billion
Step 2: Substitute the given values into the GDP formula and calculate
GDP = $300 + $100 + I+ (−$20)
GDP = $400 + I−$20
I=GDP −$400 + $20
I=GDP −$380
Step 3: Substitute the value of I into the GDP formula
GDP = $400 + (GDP −$380) −$20
GDP = $400 + GDP −$380 −$20
2GDP = $400 −$380 −$20
2GDP = $0
GDP = $0
Therefore, the country’s GDP using the expenditure approach is
$
0 billion.

Step 2: Substitute the given values for consumption (C), investment (I),
government spending (G), and net exports (NX) into the formula:
GDP =
5000 + 2000+1500 + 1000
Step 3: Add the values to find the GDP:
11
GDP =
9500 + 1500+1000
GDP =

Question 16
Question
Suppose a country’s Gross Domestic Product (GDP) in a particular year is
$
10
trillion. If the consumption expenditure is
$
6 trillion, investment expenditure
is
$
2 trillion, government expenditure is
$
1.5 trillion, and net exports are -
$
0.5
trillion, what is the formula for calculating GDP in this scenario?
Solution
To calculate the GDP using expenditure approach, we use the formula:
GDP = Consumption + Investment + Government Spending + Net Exports
We are given the following values:
Consumption expenditure =
$
6 trillion
Investment expenditure =
$
2 trillion
Government expenditure =
$
1.5 trillion
Net exports = -
$
0.5 trillion (negative because it is a deficit)
Step 1: Substitute the values into the formula for GDP calculation.
GDP = $6 trillion + $2 trillion + $1.5 trillion + (−$0.5 trillion)
= $6 trillion + $2 trillion + $1.5 trillion −$0.5 trillion
= $9 trillion
Therefore, the formula for calculating GDP in this scenario is:
GDP = $9 trillion

$
200 billion - Government
expenditure:
$
300 billion - Exports:
$
150 billion - Imports:
$
100 billion Calcu-
late the Gross Domestic Product (GDP) for this country for the given year.
13
Solution
Step 1: To calculate the GDP, we use the formula:
GDP = Consumption+Investment+Government Spending+(Exports−Imports)
Step 2: Substituting the given values into the formula, we get:
GDP = $800 billion + $200 billion + $300 billion + ($150 billion −$100 billion)
Step 3: Calculating the values inside the parentheses first, we have:
GDP = $800 billion + $200 billion + $300 billion + $50 billion
Step 4: Adding all the values together, we find:
GDP = $800 billion + $200 billion + $300 billion + $50 billion = $1350 billion
Therefore, the GDP for this country for the given year is
$
1350 billion.
Question 18
Question
Suppose a country’s GDP for the year 2020 is
$
5 trillion, its consumption is
$
3
trillion, its investment is
$
1 trillion, and its government spending is
$
1.2 trillion.
Calculate the country’s net exports for 2020.
Solution
Step 1: Recall the formula for calculating GDP:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 2: Substitute the given values into the formula to solve for net exports:
5 trillion = 3 trillion + 1 trillion + 1.2 trillion + Net Exports
Step 3: Rearrange the equation to solve for net exports:
Net Exports = 5 trillion −3 trillion −1 trillion −1.2 trillion
Step 4: Perform the arithmetic to find the net exports:
Net Exports = 5 trillion −5.2 trillion = −0.2 trillion
Step 5: Interpret the negative value of net exports. A negative value indi-
cates that the country is importing more goods and services than it is exporting.
In this case, the country has a trade deficit of
$
0.2 trillion for the year 2020.

Calculate the Gross Domestic Product (GDP) of the country for the year.
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach:
GDP = Consumption+Investment+Government Spending+(Exports−Imports)
GDP = $5 trillion + $2 trillion + $2.5 trillion + ($1.2 trillion −$0.8 trillion)
Step 2: Calculate the value inside the parentheses:
$1.2 trillion −$0.8 trillion = $0.4 trillion
16
Step 3: Substitute this back into the GDP formula and calculate:
GDP = $5 trillion + $2 trillion + $2.5 trillion + $0.4 trillion
GDP = $10.9 trillion
Therefore, the Gross Domestic Product (GDP) of the country for the year
is
$
10.9 trillion.

Question 23
Question
A country’s economy is divided into three sectors: agriculture, manufacturing,
and services. The following table shows the value added by each sector and the
intermediate goods used by each sector in a given year.
Sector Value Added (in
$
) Intermediate Goods (in
$
)
Agriculture 500,000 100,000
Manufacturing 800,000 200,000
Services 1,200,000 300,000
Calculate the Gross Domestic Product (GDP) of the country based on the
information provided.
Solution
Step 1: Calculate the GDP using the expenditure approach.
The GDP can be calculated as the sum of consumption (C), investment (I),
government spending (G), and net exports (NX):
GDP =C+I+G+NX
Step 2: Calculate the components of the GDP:
1. Consumption (C) is the total value of all goods and services consumed by
households. It can be calculated as the total value added by all sectors, minus
the value of intermediate goods used.
C= Value Added by Agriculture+Value Added by Manufacturing+Value Added by Services−Intermediate Goods Used
C= 500,000 + 800,000 + 1,200,000 −(100,000 + 200,000 + 300,000)
C= 500,000 + 800,000 + 1,200,000 −600,000
C= 1,900,000 −600,000
C= 1,300,000
2. Investment (I) is the total value of all new machinery, equipment, and
buildings produced in the country. Since no information is given about invest-
ment, let’s assume it is 200,000
$
.
18
I= 200,000
3. Government spending (G) is the total value of goods and services bought
by the government. Since no information is given about government spending,
let’s assume it is 400,000
$
.
G= 400,000
4. Net exports (NX) is the value of exports minus the value of imports.
Since no information is given about net exports, let’s assume it is 0
$
.
NX = 0
Step 3: Substitute the values into the GDP formula to find the GDP:
GDP =C+I+G+NX
GDP = 1,300,000 + 200,000 + 400,000 + 0
GDP = 1,900,000
Therefore, the Gross Domestic Product (GDP) of the country is 1,900,000
$
.

$
200 billion
Government expenditure:
$
300 billion
Exports:
$
150 billion
Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) of the country for this year.
19
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach formula:
GDP = Consumption + Investment + Government + (Exports −Imports)
Step 2: Substitute the given values into the formula:
GDP = $500 billion + $200 billion + $300 billion + ($150 billion −$100 billion)
Step 3: Perform the calculations:
GDP = $500 billion + $200 billion + $300 billion + $50 billion
GDP = $1050 billion
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
1050 billion.
Question 25
Question
Suppose a country has the following data for a particular year:
Consumption:
$
800 billion
Investment:
$
200 billion
Government spending:
$
300 billion
Exports:
$
150 billion
Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) using the expenditure approach.
Solution
To calculate the GDP using the expenditure approach, we sum up the compo-
nents of expenditure which are consumption, investment, government spending,
exports minus imports.
GDP = Consumption + Investment + Government spending + Exports −Imports
GDP = $800 billion + $200 billion + $300 billion + $150 billion −$100 billion
GDP = $1350 billion
Therefore, the Gross Domestic Product (GDP) for the country is
$
1350
billion.

Question 26
Question
Suppose a country’s economy produces only three goods: cars, computers, and
televisions. The quantities produced and their respective prices are as follows:
Good Quantity Produced Price per Unit (
$
)
Cars 500 20000
Computers 1000 1500
Televisions 2000 800
Calculate the Gross Domestic Product (GDP) using both the production ap-
proach and the expenditure approach.
Solution
Step 1: Calculate GDP using the production approach. GDP can be calculated
by summing up the value added at each stage of production. The value added is
the difference between the price of the good and the cost of intermediate goods
used in producing that good.
Value Added Cars = 500 ×20000
= 10000000
Value Added Computers = 1000 ×1500
= 1500000
Value Added Televisions = 2000 ×800
= 1600000
Therefore, the GDP using the production approach is the sum of the value
added for all goods:
GDPproduction = 10000000 + 1500000 + 1600000 = 13100000 USD
Step 2: Calculate GDP using the expenditure approach. GDP can also be
calculated by summing up all the expenditures on final goods and services.
Expenditure on Cars = 500 ×20000
= 10000000
Expenditure on Computers = 1000 ×1500
= 1500000
Expenditure on Televisions = 2000 ×800
= 1600000
21
Plugging these values into the GDP formula using the expenditure approach:
GDPexpenditure = 10000000 + 1500000 + 1600000 = 13100000 USD
Therefore, the GDP using the production approach and the expenditure
approach is both
$
13,100,000.
Question 27
Question
Suppose a country’s economy can be described by the following information:
- Consumption:
$
800 billion - Investment:
$
200 billion - Government spend-
ing:
$
300 billion - Exports:
$
150 billion - Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) of this country based on the
provided information.
Solution
To calculate the Gross Domestic Product (GDP) of a country, we can use the
equation:
GDP = Consumption+Investment+Government spending+Exports−Imports
Step 1: Plug in the given values into the GDP equation.
GDP = 800 billion + 200 billion + 300 billion + 150 billion −100 billion
Step 2: Perform the arithmetic operations.
GDP = 800 billion + 200 billion + 300 billion + 150 billion −100 billion
GDP = 1450 billion
Therefore, the Gross Domestic Product (GDP) of this country is
$
1450 bil-
lion.
Question 28
Question
Suppose a country’s GDP is calculated using the production approach with the
following data:
Value of total sales in the manufacturing sector: $500 million
22
Value of intermediate inputs purchased by the manufacturing sector: $100
million
Wages paid to workers in the manufacturing sector: $150 million
Rent and utilities paid by the manufacturing sector: $50 million
Profit earned by the manufacturing sector: $200 million
Calculate the Gross Domestic Product (GDP) using the production approach
for this country.
Solution
Step 1: Calculate the value added in the manufacturing sector.
Value Added = Total Sales −Intermediate Inputs
Value Added = $500 million −$100 million = $400 million
Step 2: Calculate the GDP using the production approach.
GDP = Value Added + Wages + Rent and Utilities + Profit
GDP = $400 million + $150 million + $50 million + $200 million = $800 million
Therefore, the Gross Domestic Product (GDP) using the production ap-
proach for this country is $800 million.
Question 29
Question

$
1 trillion
Exports:
$
0.8 trillion
Imports:
$
0.6 trillion
Calculate the Gross Domestic Product (GDP) of the country.
23
Solution
To calculate the GDP of a country, we can use the formula:
GDP = Consumption+Investment+Government Spending+Exports−Imports
Step 1: Calculate the GDP using the given components:
GDP = $3 trillion + $1.5 trillion + $1 trillion + $0.8 trillion −$0.6 trillion
GDP = $4.7 trillion
Therefore, the Gross Domestic Product (GDP) of the country is
$
4.7 trillion.
Question 30
Question
The table below shows the values for consumption, investment, government
spending, exports, and imports for a hypothetical country in a given year. Cal-
culate the Gross Domestic Product (GDP) for this country for that year.
Component Value (in billions)
Consumption $700

Government Spending $200
Exports $100
Imports $120
Solution
Step 1: Calculate Net Exports.
Net Exports = Exports −Imports
Net Exports = $100 −$120 = −$20 billion
Step 2: Calculate GDP using the expenditure approach.
GDP = Consumption + Investment + Government Spending + Net Exports
GDP = $700 + $150 + $200 + (−$20)
GDP = $1030 billion
Therefore, the Gross Domestic Product (GDP) for the country in that year
is
$
1030 billion.

Question 31
Question
Let’s consider an economy with the following values: consumption expenditure
(C) = 500, investment expenditure (I) = 200, government expenditure (G) =
150, exports (X) = 100, and imports (M) = 50. Calculate the Gross Domestic
Product (GDP) using the expenditure approach.
Solution
To calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach, we sum up all the components of final expenditures in the economy,
which are consumption (C), investment (I), government spending (G), exports
(X), and subtracting imports (M) since they represent spending on goods and
services produced abroad.
GDP = C+I+G+ (X−M)
Step 1: Given values are C= 500, I= 200, G= 150, X= 100, and
M= 50.
Step 2: Plug in the values into the formula for GDP:
GDP = 500 + 200 + 150 + (100 −50)
Step 3: Perform the calculations:
GDP = 500 + 200 + 150 + 50
GDP = 850 + 200
GDP = 1050
Therefore, the Gross Domestic Product (GDP) for this economy is 1050.

Calculate the Gross Domestic Product (GDP) for this country in this year.
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach:
GDP = Consumption (C)+Investment (I)+Government Spending (G)+Net Exports (NX)
Where:
NX = Exports −Imports
NX = 100 billion −80 billion = 20 billion
GDP = 500 billion + 200 billion + 150 billion + 20 billion = 870 billion
Therefore, the Gross Domestic Product (GDP) for this country in the given
year is
$
870 billion.
Question 35
Question
A country’s economy consists of three sectors - agriculture, manufacturing, and
services. The following table shows the output (in millions of dollars) and the
price index for each sector:
Sector Output (in millions of dollars) Price Index
Agriculture 500 110
Manufacturing 800 120
Services 1200 130
Calculate the country’s nominal GDP and real GDP using 2015 as the base
year.
27
Solution
Step 1: Calculate the nominal GDP by multiplying the output by the price
index for each sector and summing the results.
For agriculture:
Agriculture Nominal GDP = 500 ×110 = 55000 million dollars
For manufacturing:
Manufacturing Nominal GDP = 800 ×120 = 96000 million dollars
For services:
Services Nominal GDP = 1200 ×130 = 156000 million dollars
Therefore, the country’s nominal GDP is the sum of the nominal GDP of
each sector:
Nominal GDP = 55000 + 96000 + 156000 = 307000 million dollars
Step 2: Calculate the real GDP using 2015 as the base year. The real GDP is
calculated by multiplying the output by the price index of the base year (2015)
for each sector and summing the results.
For agriculture:
Agriculture Real GDP = 500 ×110 = 55000 million dollars
For manufacturing:
Manufacturing Real GDP = 800 ×120 = 96000 million dollars
For services:
Services Real GDP = 1200 ×130 = 156000 million dollars
Therefore, the country’s real GDP is the sum of the real GDP of each sector:
Real GDP (2015) = 55000 + 96000 + 156000 = 307000 million dollars
Thus, the country’s nominal GDP and real GDP for the year is 307,000
million dollars.
28
Step 3: Substitute the values into the formula and calculate the GDP.
GDP = 200 + 100 + 50 + 10 = 360 billion
Therefore, the Gross Domestic Product (GDP) for this economy is 360 bil-
lion.

$
300 bil-
lion
Net Exports:
$
50 billion
Calculate the country’s GDP using the expenditure approach.
Solution
To calculate the country’s GDP using the expenditure approach, we sum up the
various components: Personal Consumption Expenditures (C), Gross Private
Domestic Investment (I), Government Consumption Expenditures and Gross
Investment (G), and Net Exports (NX).
Step 1: Write down the formula for GDP using the expenditure approach:
GDP =C+I+G+NX
Step 2: Given data:
C= $800 billion
I= $200 billion
G= $300 billion
NX = $50 billion
Step 3: Substitute the given values into the GDP formula:
GDP = $800 billion + $200 billion + $300 billion + $50 billion
Step 4: Simplify the expression by adding the values:
GDP = $1350 billion
Therefore, the country’s GDP using the expenditure approach is
$

Solution
Step 1: Calculate Net Exports
Net Exports = Exports −Imports = $100 billion −$80 billion = $20 billion
Step 2: Calculate GDP
GDP = Consumption + Investment + Government Spending + Net Exports
GDP = $500 billion + $200 billion + $150 billion + $20 billion = $870 billion
Therefore, the Gross Domestic Product (GDP) of the fictional country is
$
870 billion.
Question 4
Question
Suppose a country’s economy produces only three goods: apples, oranges, and

$1.50
Oranges 150 $2 200
$2.50
Bananas 80 $0.50 100
$0.75
Calculate the Gross Domestic Product (GDP) for year 1 and year 2 using
both the formula approach and the expenditure approach.
3
Solution
Let’s calculate the Gross Domestic Product (GDP) for year 1 and year 2 using
both the formula approach and the expenditure approach.
Formula Approach: Step 1: Calculate nominal GDP using the formula
approach:
Nominal GDP = X(Price ×Quantity)
For year 1:
Nominal GDP (year 1) = (100×1)+(150×2)+(80×0.5) = 100+300+40 = $440
For year 2:
Nominal GDP (year 2) = (120×1.5)+(200×2.5)+(100×0.75) = 180+500+75 = $755
Step 2: Adjust for inflation using the GDP deflator to calculate real GDP:
GDP Deflator = Nominal GDP
Real GDP ×100
For year 1:
GDP Deflator (year 1) = 440
440×100 = 100
For year 2:
GDP Deflator (year 2) = 755
440×100 ≈171.59
Expenditure Approach: Step 1: Calculate GDP using the expenditure
approach:
GDP = C+I+G+ (X−M)
Where: - C= Household consumption - I= Investment - G= Government
spending - X= Exports - M= Imports
For both years:
C= (100 ×1) + (150 ×2) + (80 ×0.5) + (120 ×1.5) + (200 ×2.5) + (100 ×0.75)
C= 440 + 315 = $755
Therefore, the GDP for year 1 and year 2 using both methods are as follows:
- Nominal GDP (year 1):
$
440, Nominal GDP (year 2):
$
755 - Real GDP (year
1):
$
440, Real GDP (year 2):
$
440 - GDP Deflator (year 1): 100, GDP Deflator
(year 2): 171.59

Step 1: Calculate the value of exports minus imports.
X−M= 150 −120 = 30 billion
Step 2: Substitute the given values into the GDP formula and solve for
GDP.
GDP = 800 + 200 + 300 + 30

Net Exports = Exports −Imports
Net Exports = 50 billion −30 billion
Net Exports = 20 billion
Step 2: Calculate the GDP using the expenditure approach.
GDP = Consumption + Investment + Government + Net Exports
GDP = 400 billion + 150 billion + 100 billion + 20 billion
GDP = 670 billion
Therefore, the Gross Domestic Product (GDP) calculated using the expen-
diture approach is 670 billion.

GDP = $300 + $100 + I+ (−$20)
GDP = $400 + I−$20
I=GDP −$400 + $20
I=GDP −$380
Step 3: Substitute the value of I into the GDP formula
GDP = $400 + (GDP −$380) −$20
GDP = $400 + GDP −$380 −$20

GDP = $800 billion + $200 billion + $300 billion + $50 billion = $1350 billion
Therefore, the GDP for this country for the given year is
$
1350 billion.
Question 18
Question
Suppose a country’s GDP for the year 2020 is
$
5 trillion, its consumption is
$
3
trillion, its investment is
$
1 trillion, and its government spending is
$
1.2 trillion.
Calculate the country’s net exports for 2020.
Solution
Step 1: Recall the formula for calculating GDP:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 2: Substitute the given values into the formula to solve for net exports:
5 trillion = 3 trillion + 1 trillion + 1.2 trillion + Net Exports
Step 3: Rearrange the equation to solve for net exports:
Net Exports = 5 trillion −3 trillion −1 trillion −1.2 trillion
Step 4: Perform the arithmetic to find the net exports:
Net Exports = 5 trillion −5.2 trillion = −0.2 trillion
Step 5: Interpret the negative value of net exports. A negative value indi-
cates that the country is importing more goods and services than it is exporting.
In this case, the country has a trade deficit of
$
0.2 trillion for the year 2020.

Question 23
Question
A country’s economy is divided into three sectors: agriculture, manufacturing,
and services. The following table shows the value added by each sector and the
intermediate goods used by each sector in a given year.
Sector Value Added (in
$
) Intermediate Goods (in
$
)
Agriculture 500,000 100,000
Manufacturing 800,000 200,000
Services 1,200,000 300,000
Calculate the Gross Domestic Product (GDP) of the country based on the
information provided.
Solution
Step 1: Calculate the GDP using the expenditure approach.
The GDP can be calculated as the sum of consumption (C), investment (I),
government spending (G), and net exports (NX):
GDP =C+I+G+NX
Step 2: Calculate the components of the GDP:
1. Consumption (C) is the total value of all goods and services consumed by
households. It can be calculated as the total value added by all sectors, minus
the value of intermediate goods used.
C= Value Added by Agriculture+Value Added by Manufacturing+Value Added by Services−Intermediate Goods Used
C= 500,000 + 800,000 + 1,200,000 −(100,000 + 200,000 + 300,000)
C= 500,000 + 800,000 + 1,200,000 −600,000
C= 1,900,000 −600,000
C= 1,300,000
2. Investment (I) is the total value of all new machinery, equipment, and
buildings produced in the country. Since no information is given about invest-
ment, let’s assume it is 200,000
$
.
18
I= 200,000
3. Government spending (G) is the total value of goods and services bought
by the government. Since no information is given about government spending,
let’s assume it is 400,000
$
.
G= 400,000
4. Net exports (NX) is the value of exports minus the value of imports.
Since no information is given about net exports, let’s assume it is 0
$
.
NX = 0
Step 3: Substitute the values into the GDP formula to find the GDP:
GDP =C+I+G+NX
GDP = 1,300,000 + 200,000 + 400,000 + 0
GDP = 1,900,000
Therefore, the Gross Domestic Product (GDP) of the country is 1,900,000
$
.
Question 24

$
300 billion
Exports:
$
150 billion
Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) of the country for this year.
19
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach formula:
GDP = Consumption + Investment + Government + (Exports −Imports)
Step 2: Substitute the given values into the formula:
GDP = $500 billion + $200 billion + $300 billion + ($150 billion −$100 billion)
Step 3: Perform the calculations:
GDP = $500 billion + $200 billion + $300 billion + $50 billion
GDP = $1050 billion
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
1050 billion.
Question 25
Question
Suppose a country has the following data for a particular year:
Consumption:
$
800 billion
Investment:
$
200 billion
Government spending:
$
300 billion
Exports:
$
150 billion
Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) using the expenditure approach.
Solution
To calculate the GDP using the expenditure approach, we sum up the compo-
nents of expenditure which are consumption, investment, government spending,
exports minus imports.
GDP = Consumption + Investment + Government spending + Exports −Imports
GDP = $800 billion + $200 billion + $300 billion + $150 billion −$100 billion
GDP = $1350 billion
Therefore, the Gross Domestic Product (GDP) for the country is
$
1350
billion.
20
Question 26
Question
Suppose a country’s economy produces only three goods: cars, computers, and
televisions. The quantities produced and their respective prices are as follows:
Good Quantity Produced Price per Unit (
$
)
Cars 500 20000
Computers 1000 1500
Televisions 2000 800
Calculate the Gross Domestic Product (GDP) using both the production ap-
proach and the expenditure approach.
Solution
Step 1: Calculate GDP using the production approach. GDP can be calculated
by summing up the value added at each stage of production. The value added is
the difference between the price of the good and the cost of intermediate goods
used in producing that good.
Value Added Cars = 500 ×20000
= 10000000
Value Added Computers = 1000 ×1500
= 1500000
Value Added Televisions = 2000 ×800
= 1600000
Therefore, the GDP using the production approach is the sum of the value
added for all goods:
GDPproduction = 10000000 + 1500000 + 1600000 = 13100000 USD
Step 2: Calculate GDP using the expenditure approach. GDP can also be
calculated by summing up all the expenditures on final goods and services.
Expenditure on Cars = 500 ×20000
= 10000000
Expenditure on Computers = 1000 ×1500
= 1500000
Expenditure on Televisions = 2000 ×800
= 1600000
21
Plugging these values into the GDP formula using the expenditure approach:
GDPexpenditure = 10000000 + 1500000 + 1600000 = 13100000 USD
Therefore, the GDP using the production approach and the expenditure
approach is both
$
13,100,000.
Question 27
Question
Suppose a country’s economy can be described by the following information:
- Consumption:
$
800 billion - Investment:
$
200 billion - Government spend-
ing:
$
300 billion - Exports:
$
150 billion - Imports:
$
100 billion
Calculate the Gross Domestic Product (GDP) of this country based on the
provided information.
Solution
To calculate the Gross Domestic Product (GDP) of a country, we can use the
equation:
GDP = Consumption+Investment+Government spending+Exports−Imports
Step 1: Plug in the given values into the GDP equation.
GDP = 800 billion + 200 billion + 300 billion + 150 billion −100 billion
Step 2: Perform the arithmetic operations.
GDP = 800 billion + 200 billion + 300 billion + 150 billion −100 billion
GDP = 1450 billion
Therefore, the Gross Domestic Product (GDP) of this country is
$
1450 bil-
lion.
Question 28
Question
Suppose a country’s GDP is calculated using the production approach with the
following data:
Value of total sales in the manufacturing sector: $500 million
22
Value of intermediate inputs purchased by the manufacturing sector: $100
million
Wages paid to workers in the manufacturing sector: $150 million
Rent and utilities paid by the manufacturing sector: $50 million
Profit earned by the manufacturing sector: $200 million
Calculate the Gross Domestic Product (GDP) using the production approach
for this country.
Solution
Step 1: Calculate the value added in the manufacturing sector.
Value Added = Total Sales −Intermediate Inputs
Value Added = $500 million −$100 million = $400 million
Step 2: Calculate the GDP using the production approach.
GDP = Value Added + Wages + Rent and Utilities + Profit
GDP = $400 million + $150 million + $50 million + $200 million = $800 million
Therefore, the Gross Domestic Product (GDP) using the production ap-
proach for this country is $800 million.
Question 29
Question

$
1 trillion
Exports:
$
0.8 trillion
Imports:
$
0.6 trillion
Calculate the Gross Domestic Product (GDP) of the country.
23
Solution
To calculate the GDP of a country, we can use the formula:
GDP = Consumption+Investment+Government Spending+Exports−Imports
Step 1: Calculate the GDP using the given components:
GDP = $3 trillion + $1.5 trillion + $1 trillion + $0.8 trillion −$0.6 trillion
GDP = $4.7 trillion
Therefore, the Gross Domestic Product (GDP) of the country is
$
4.7 trillion.
Question 30
Question
The table below shows the values for consumption, investment, government
spending, exports, and imports for a hypothetical country in a given year. Cal-
culate the Gross Domestic Product (GDP) for this country for that year.
Component Value (in billions)
Consumption $700
Investment $150
Government Spending $200
Exports $100
Imports $120
Solution
Step 1: Calculate Net Exports.
Net Exports = Exports −Imports
Net Exports = $100 −$120 = −$20 billion
Step 2: Calculate GDP using the expenditure approach.
GDP = Consumption + Investment + Government Spending + Net Exports
GDP = $700 + $150 + $200 + (−$20)
GDP = $1030 billion
Therefore, the Gross Domestic Product (GDP) for the country in that year
is
$
1030 billion.

Question 31
Question
Let’s consider an economy with the following values: consumption expenditure
(C) = 500, investment expenditure (I) = 200, government expenditure (G) =
150, exports (X) = 100, and imports (M) = 50. Calculate the Gross Domestic
Product (GDP) using the expenditure approach.
Solution
To calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach, we sum up all the components of final expenditures in the economy,
which are consumption (C), investment (I), government spending (G), exports
(X), and subtracting imports (M) since they represent spending on goods and
services produced abroad.
GDP = C+I+G+ (X−M)
Step 1: Given values are C= 500, I= 200, G= 150, X= 100, and
M= 50.
Step 2: Plug in the values into the formula for GDP:
GDP = 500 + 200 + 150 + (100 −50)
Step 3: Perform the calculations:
GDP = 500 + 200 + 150 + 50
GDP = 850 + 200
GDP = 1050
Therefore, the Gross Domestic Product (GDP) for this economy is 1050.

=
$
150 billion -
$
100 billion Net Export =
$
50 billion
Step 2: Calculate GDP using the Expenditure Approach GDP = Consump-
tion expenditure + Investment + Government spending + Net Export GDP =
$
800 billion +
$
200 billion +
$
300 billion +
$
50 billion GDP =
$
1,350 billion
Therefore, the Gross Domestic Product (GDP) is
$
1,350 billion.

Step 1: Calculate GDP by substituting the given values into the formula
GDP = 500 + 200 + 100 + 50 −30
Step 2: Compute the total GDP
GDP = 820 billion
Therefore, the Gross Domestic Product (GDP) of the country for that year
is
$
820 billion.
26
Question 34
Question
In a hypothetical country, the following data is given for a particular year:
Consumption expenditure:
$

Calculate the Gross Domestic Product (GDP) for this country in this year.
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach:
GDP = Consumption (C)+Investment (I)+Government Spending (G)+Net Exports (NX)
Where:
NX = Exports −Imports
NX = 100 billion −80 billion = 20 billion
GDP = 500 billion + 200 billion + 150 billion + 20 billion = 870 billion
Therefore, the Gross Domestic Product (GDP) for this country in the given
year is
$
870 billion.
Question 35
Question
A country’s economy consists of three sectors - agriculture, manufacturing, and
services. The following table shows the output (in millions of dollars) and the
price index for each sector:
Sector Output (in millions of dollars) Price Index
Agriculture 500 110
Manufacturing 800 120
Services 1200 130
Calculate the country’s nominal GDP and real GDP using 2015 as the base
year.
27
Solution
Step 1: Calculate the nominal GDP by multiplying the output by the price
index for each sector and summing the results.
For agriculture:
Agriculture Nominal GDP = 500 ×110 = 55000 million dollars
For manufacturing:
Manufacturing Nominal GDP = 800 ×120 = 96000 million dollars
For services:
Services Nominal GDP = 1200 ×130 = 156000 million dollars
Therefore, the country’s nominal GDP is the sum of the nominal GDP of
each sector:
Nominal GDP = 55000 + 96000 + 156000 = 307000 million dollars
Step 2: Calculate the real GDP using 2015 as the base year. The real GDP is
calculated by multiplying the output by the price index of the base year (2015)
for each sector and summing the results.
For agriculture:
Agriculture Real GDP = 500 ×110 = 55000 million dollars
For manufacturing:
Manufacturing Real GDP = 800 ×120 = 96000 million dollars
For services:
Services Real GDP = 1200 ×130 = 156000 million dollars
Therefore, the country’s real GDP is the sum of the real GDP of each sector:
Real GDP (2015) = 55000 + 96000 + 156000 = 307000 million dollars
Thus, the country’s nominal GDP and real GDP for the year is 307,000
million dollars.
