GDP - Gross Domestic Product GDP Deflator and Inflation Questions and Answers — Questions and Answers
Question 1: An economy's nominal GDP was $15 trillion in Year 1 and $16.5 trillion in Year 2. The real GDP was $14 trillion in Year 1 and $14.8 trillion in Year 2. What was the approximate inflation rate between Year 1 and Year 2 as measured by the GDP deflator?
- A) 10.0%
- B) 3.2%
- C) 5.7%
- D) 4.1% (Correct answer)
Correct answer: D) 4.1%
To find the inflation rate, first calculate the GDP deflator for each year using the formula: GDP Deflator = (Nominal GDP / Real GDP) * 100. For Year 1: ($15T / $14T) * 100 ≈ 107.14. For Year 2: ($16.5T / $14.8T) * 100 ≈ 111.49. Then, calculate the percentage change between the two deflators: ((111.49 - 107.14) / 107.14) * 100 ≈ 4.1%.
Question 2: Which of the following statements most accurately distinguishes the GDP deflator from the Consumer Price Index (CPI)?
- A) The GDP deflator uses a fixed basket of goods and services, whereas the CPI's basket changes annually based on production.
- B) The CPI includes the prices of imported goods purchased by consumers, while the GDP deflator excludes them. (Correct answer)
- C) The GDP deflator measures the prices of consumer goods only, while the CPI measures consumer, investment, and government goods.
- D) The CPI is published quarterly, whereas the GDP deflator is published monthly.
Correct answer: B) The CPI includes the prices of imported goods purchased by consumers, while the GDP deflator excludes them.
A key difference between the two inflation measures is their treatment of foreign goods. The CPI includes goods purchased by consumers, regardless of where they are produced, so it includes imports. The GDP deflator measures the prices of all goods and services produced domestically, so it excludes imports but includes exports.
Question 3: If an economy's nominal GDP is $22 trillion and its real GDP is $20 trillion, what is the value of the GDP deflator?
- A) 110 (Correct answer)
- B) 90.9
- C) 100
- D) 1.1
Correct answer: A) 110
The GDP deflator is calculated using the formula: GDP Deflator = (Nominal GDP / Real GDP) * 100. In this case, ($22 trillion / $20 trillion) * 100 = 1.1 * 100 = 110.
Question 4: A country's GDP deflator in the current year is 125, using Year X as the base year. What is the correct interpretation of this value?
- A) Real GDP is 25% higher than nominal GDP.
- B) The inflation rate for the current year is 25%.
- C) The overall price level has increased by 25% since the base year, Year X. (Correct answer)
- D) The economy's output of goods and services has grown by 25% since the base year.
Correct answer: C) The overall price level has increased by 25% since the base year, Year X.
The GDP deflator measures the overall change in the price level relative to a base year, which is set to 100. A deflator of 125 indicates that the aggregate price level has risen by 25% since the base year.
Question 5: The calculation of the GDP deflator reflects the price changes of which of the following?
- A) A fixed basket of consumer goods and services.
- B) All final goods and services purchased by a typical urban household.
- C) All domestically produced final goods and services, including those sold to firms and the government. (Correct answer)
- D) Imported consumer goods and domestically produced capital goods.
Correct answer: C) All domestically produced final goods and services, including those sold to firms and the government.
The GDP deflator is a comprehensive measure that reflects the prices of all new, domestically produced final goods and services in an economy. This includes consumption, investment, government purchases, and exports, but excludes imports.
Question 6: For the base year, what is the value of the GDP deflator and why?
- A) It is 0, because there is no inflation in the base year.
- B) It depends on the rate of economic growth in that year.
- C) It is 1, because nominal and real GDP are fractions of each other.
- D) It is 100, because nominal GDP is equal to real GDP by definition. (Correct answer)
Correct answer: D) It is 100, because nominal GDP is equal to real GDP by definition.
In the base year, real GDP is calculated using the same prices as nominal GDP. Therefore, nominal GDP equals real GDP. According to the formula (Nominal GDP / Real GDP) * 100, this results in a GDP deflator of (1) * 100 = 100.
An economy's nominal GDP was $15 trillion in Year 1 and $16.5 trillion in Year 2.
The real GDP was $14 trillion in Year 1 and $14.8 trillion in Year 2.
What was the approximate inflation rate between Year 1 and Year 2 as measured by the GDP deflator?
