Correct Option: B. Solution: GDP deflator is the ratio of nominal GDP to real GDP and indicates the change in price level from the base year to the current year.

Question 5

Which of the following is NOT included in the calculation of GDP using the expenditure method?

Accepted Answer

Correct Option: B. Solution: In the expenditure method, imports are subtracted from the total expenditure as they represent spending on foreign-produced goods and services.

Question 6

What is the primary reason for avoiding the inclusion of intermediate goods in GDP calculations?

Accepted Answer

Correct Option: A. Solution: Intermediate goods are excluded from GDP calculations to prevent double counting, as their value is already included in the value of final goods.

Question 7

In the circular flow of income, what does the arrow from households to firms represent?

Accepted Answer

Correct Option: A. Solution: The arrow from households to firms in the circular flow of income represents the spending on goods and services produced by the firms.

Question 8

Which of the following best describes the difference between nominal GDP and real GDP?

Accepted Answer

Correct Option: B. Solution: Real GDP is adjusted for inflation by using constant prices, allowing for accurate comparisons over time, whereas nominal GDP is calculated using current prices.

Question 9

How does the GDP deflator differ from the Consumer Price Index (CPI)?

Accepted Answer

Correct Option: B. Solution: CPI includes prices of imported goods, while GDP deflator does not. GDP deflator accounts for all goods and services produced domestically.

Question 10

How does the income method of calculating GDP account for the revenues earned by firms?

Accepted Answer

Correct Option: C. Solution: The income method calculates GDP by distributing the revenues earned by firms among the factors of production as wages, profits, interest, and rents.

Question 11

Which of the following best describes the circular flow of income in a simple economy?

Accepted Answer

Correct Option: A. Solution: In a simple economy, income flows from firms to households as wages, rent, etc., and returns to firms through household consumption of goods and services.

Question 12

In the circular flow of income, which of the following best describes the role of households?

Accepted Answer

Correct Option: A. Solution: In the circular flow of income, households supply factors of production such as labor, capital, and land, and in return, they receive income which they use to consume goods and services produced by firms.

Question 13

How does GDP fail to reflect the true economic welfare of a country?

Accepted Answer

Correct Option: B. Solution: GDP does not consider the distribution of income among citizens, which means it can increase while the majority of the population becomes poorer.

Question 14

If a country's GDP increases but the income distribution becomes more unequal, what can be inferred about the welfare of the population?

Accepted Answer

Correct Option: C. Solution: An increase in GDP does not necessarily mean improved welfare for everyone if the income distribution becomes more unequal, as the benefits may be concentrated among a few.

Question 15

Which of the following correctly represents the relationship between Gross Domestic Product (GDP) and Gross National Product (GNP)?

Accepted Answer

Correct Option: A. Solution: Gross National Product (GNP) is calculated by adding the net factor income from abroad to the Gross Domestic Product (GDP).

Question 16

What is the primary reason GDP might not accurately reflect the welfare of a country's population?

Accepted Answer

Correct Option: B. Solution: GDP might not reflect welfare accurately because it does not account for how income is distributed across the population. A rise in GDP could be concentrated among a few individuals, not benefiting the majority.

Question 17

What is the primary reason for using real GDP instead of nominal GDP when comparing economic performance over time?

Accepted Answer

Correct Option: B. Solution: Real GDP is used instead of nominal GDP to adjust for changes in price levels, allowing for a more accurate comparison of economic performance over time.

Question 18

Which method of calculating national income involves summing up the value of all final goods and services produced in an economy?

Accepted Answer

Correct Option: C. Solution: The product method, also known as the value added method, involves summing up the value of all final goods and services produced in an economy to calculate national income.

Question 19

In the context of GDP calculation, why is it important to distinguish between intermediate goods and final goods?

Accepted Answer

Correct Option: A. Solution: Intermediate goods are used in the production of final goods, and including them separately would result in double counting. Only final goods are included in GDP to accurately reflect the value of production.

Question 20

Which of the following is considered a flow variable in national income accounting?

Accepted Answer

Correct Option: C. Solution: Net investment is a flow variable as it measures the change in capital stock over a period of time, unlike capital stock itself, which is a stock variable.

Question 21

Which of the following statements correctly differentiates between GDP deflator and Consumer Price Index (CPI)?

Accepted Answer

Correct Option: D. Solution: The GDP deflator does not include prices of imported goods, as it measures the price level of all domestically produced goods and services. In contrast, the CPI includes prices of goods consumed by the representative consumer, including imported goods.

Question 22

Which method of calculating GDP involves summing the value added by all firms in the economy?

Accepted Answer

Correct Option: A. Solution: The Product Method involves calculating GDP by summing the value added by all firms, which is the value of their production minus the value of intermediate goods used.

Question 23

Which of the following best explains the concept of 'double counting' in the context of calculating GDP?

Question 29

In the context of calculating GDP using the product method, which of the following statements is correct?

Accepted Answer

Correct Option: B. Solution: In the product method of calculating GDP, only the value of final goods and services is considered to avoid double counting. Including the value of intermediate goods would result in counting the same value multiple times.

Question 30

Why is real GDP considered a better measure of economic performance over time compared to nominal GDP?

Accepted Answer

Correct Option: B. Solution: Real GDP is adjusted for inflation and reflects changes in the volume of production, providing a more accurate measure of economic performance over time.

Question 31

If the Gross National Product (GNP) of a country is $500$ billion and the depreciation is $50$ billion, what is the Net National Product (NNP)?

Accepted Answer

Correct Option: A. Solution: Net National Product (NNP) is calculated by subtracting depreciation from GNP. Thus, $NNP = GNP - Depreciation = 500 - 50 = 450$ billion.

Question 32

In a closed economy with no government, if the households decide to increase their spending beyond their income, what will be the likely outcome?

Accepted Answer

Correct Option: A. Solution: In a simple circular flow model, increased spending by households leads to increased production by firms, which in turn increases factor payments, eventually raising the income to match the spending.

Question 33

What is the formula for Net Investment?

Accepted Answer

Correct Option: B. Solution: Net Investment is calculated by subtracting depreciation from gross investment.

Question 34

If a tank is being filled with water from a tap, which of the following represents a flow variable?

Accepted Answer

Correct Option: B. Solution: The rate at which water flows into the tank is a flow variable because it is measured over a period of time, whereas the amount of water in the tank at a specific time is a stock variable.

Question 35

In the circular flow of income, what happens when households decide to spend more than their current income?

Accepted Answer

Correct Option: B. Solution: When households spend more than their current income, firms produce more to meet the extra demand, leading to an increase in aggregate income.

Question 36

If the nominal GDP of a country increased from $1,000$ to $1,500$ over a year, and the GDP deflator is $1.25$, what is the real GDP for the current year?

Accepted Answer

Question 45

Which of the following is a key difference between the GDP deflator and the Wholesale Price Index (WPI)?

Accepted Answer

Correct Option: A. Solution: The GDP deflator includes all goods and services produced domestically, reflecting the overall price level in the economy. In contrast, the WPI includes only wholesale goods and does not account for services.

Question 46

How does the issue of income distribution affect the interpretation of GDP as a welfare measure?

Accepted Answer

Correct Option: C. Solution: GDP may increase due to a rise in income for a small segment of the population, while the majority may experience a decrease in income, thus not accurately reflecting overall welfare.

Question 47

Which of the following is a limitation of using GDP as an indicator of welfare?

Accepted Answer

Correct Option: C. Solution: GDP does not account for negative externalities like pollution, which can decrease overall welfare despite an increase in GDP.

Question 48

If the nominal GDP of a country increased from $1,500$ billion to $1,650$ billion and the real GDP increased from $1,100$ billion to $1,200$ billion, what is the GDP deflator for the current year?

Accepted Answer

Question 50

In the expenditure method of calculating GDP, which of the following is NOT included in the final expenditure?

Accepted Answer

Correct Option: C. Solution: Expenditure on intermediate goods is not included in the final expenditure because they are used up in the production process and their value is already included in the final goods.

Question 51

A common misconception is that all gross investment contributes to an increase in capital stock. Why is this incorrect?

Accepted Answer

Correct Option: A. Solution: Gross investment includes depreciation which is used to maintain existing capital stock rather than increasing it.

Question 52

If a firm has an unsold inventory at the end of the year, how is it treated in GDP calculations?
