GDP - Gross Domestic Product GDP Calculation Methods Questions and Answers — Questions and Answers
Question 1: An economist is calculating a country's Gross Domestic Product (GDP) using the expenditure approach. Which of the following transactions would be included in the calculation?
- A homeowner purchasing a newly built house. (Correct answer)
- A car manufacturer purchasing tires to install on new vehicles.
- The government issuing social security payments to retirees.
- An individual purchasing shares of stock in a publicly traded company.
Correct answer: A homeowner purchasing a newly built house.
The expenditure approach to GDP is calculated as C + I + G + (X-M). The purchase of a newly built house is considered part of Investment (I) and is therefore included in the GDP calculation. The purchase of tires by a car manufacturer is an intermediate good, social security is a transfer payment, and buying stocks is a financial transaction; none of these are included in GDP.
Question 2: The income approach to calculating GDP sums up all the income earned by factors of production. Which of the following is NOT a component of the income approach?
- Wages and salaries paid to employees.
- Rental income earned by property owners.
- Government purchases of goods and services. (Correct answer)
- Corporate profits before tax.
Correct answer: Government purchases of goods and services.
The income approach sums factor incomes like wages, rents, interest, and profits. Government purchases of goods and services is a component of the expenditure approach (G in the C+I+G+(X-M) formula), not the income approach.
Question 3: A steel company sells steel to a bicycle manufacturer for $200. The bicycle manufacturer uses the steel to produce a bicycle, which it sells to a retailer for $500. The retailer then sells the bicycle to a customer for $700. Using the value-added approach, what is the total contribution to GDP from these transactions?
- $1,400
- $500
- $700 (Correct answer)
- $1,000
Correct answer: $700
The value-added approach sums the value added at each stage of production to avoid double-counting. The steel company adds $200. The bicycle manufacturer adds $300 ($500 - $200). The retailer adds $200 ($700 - $500). The total value added is $200 + $300 + $200 = $700, which is equal to the final market price of the bicycle.
Question 4: Which of the following is explicitly excluded from the calculation of a country's Gross Domestic Product (GDP)?
- The estimated rental value of owner-occupied housing.
- Services produced by the government, such as national defense.
- The sale of illegal goods and services on the black market. (Correct answer)
- Exports of final goods and services to other countries.
Correct answer: The sale of illegal goods and services on the black market.
GDP measures the market value of all final goods and services produced within a country. Transactions that occur in the black market (illegal goods and services) are not recorded and are therefore excluded from official GDP calculations.
Question 5: To avoid double-counting in the calculation of GDP, economists primarily include the value of:
- both final and intermediate goods.
- intermediate goods only.
- final goods and services only. (Correct answer)
- all raw materials used in production.
Correct answer: final goods and services only.
GDP only includes the market value of final goods and services. The value of intermediate goods (goods used in the production of other goods) is already incorporated into the price of the final good. Including them separately would result in counting their value multiple times.
Question 6: If a country's GDP is calculated using the formula: GDP = C + I + G + (X - M), which calculation method is being used?
- The Income Approach
- The Expenditure Approach (Correct answer)
- The Production (Value-Added) Approach
- The National Savings Approach
Correct answer: The Expenditure Approach
The formula GDP = C + I + G + (X - M) represents the expenditure approach, where C is Consumption, I is Investment, G is Government Spending, and (X - M) is Net Exports. This method sums up all spending on final goods and services in an economy.
An economist is calculating a country's Gross Domestic Product (GDP) using the expenditure approach.
