Q: Suppose in 2017, a country produced 100 eye exams at $$40 each, 80 pizzas at 11 $$each, and 20 shoes at $90 each. What is the nominal GDP for 2017?

$$100 \times 40 + 80 \times 11 + 20 \times 90 = 5,540$$

Q: If the nominal GDP in 2017 is $$5,540 and in 2025 is 7$$,800, what is the percentage growth in nominal GDP over this period?

$$\frac{7,800 - 5,540}{5,540} \times 100 = 40.8\%$$

Q: Given the following data for 2025: 100 eye exams at $$50 each, 80 pizzas at 10 $$each, and 20 shoes at $110 each, what is the nominal GDP for 2025?

$$100 \times 50 + 80 \times 10 + 20 \times 110 = 7,800$$

Q: Using 2017 as the base year, calculate the real GDP for 2025 using the quantities from 2025 and prices from 2017: 100 eye exams ($$40), 80 pizzas (11$$), 20 shoes ($90).

$$100 \times 40 + 80 \times 11 + 20 \times 90 = 5,540$$

Q: Which formula correctly calculates the GDP deflator?

$$\frac{\text{Nominal GDP}}{\text{Real GDP}} \times 100$$

Q: If the nominal GDP in 2025 is $$7,800 and the real GDP (base year 2017) is 5$$,540, what is the GDP deflator for 2025?

$$\frac{7,800}{5,540} \times 100 = 140.8$$

Question 1

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

Accepted Answer

Nominal GDP is measured using current prices, while real GDP is measured using constant (base-year) prices.

Question 2

Suppose in 2017, a country produced 100 eye exams at $$40 each, 80 pizzas at 11 $$each, and 20 shoes at $90 each. What is the nominal GDP for 2017?

Accepted Answer

$$100 	imes 40 + 80 	imes 11 + 20 	imes 90 = 5,540$$

Question 3

If the nominal GDP in 2017 is $$5,540 and in 2025 is 7$$,800, what is the percentage growth in nominal GDP over this period?

Accepted Answer

$$\frac{7,800 - 5,540}{5,540} 	imes 100 = 40.8\%$$

Question 4

Why is real GDP considered a better measure of economic growth than nominal GDP?

Accepted Answer

Real GDP eliminates the effect of price changes by using constant base-year prices.

Question 5

Given the following data for 2025: 100 eye exams at $$50 each, 80 pizzas at 10 $$each, and 20 shoes at $110 each, what is the nominal GDP for 2025?

Accepted Answer

$$100 	imes 50 + 80 	imes 10 + 20 	imes 110 = 7,800$$

Question 6

Using 2017 as the base year, calculate the real GDP for 2025 using the quantities from 2025 and prices from 2017: 100 eye exams ($$40), 80 pizzas (11$$), 20 shoes ($90).

Accepted Answer

$$100 	imes 40 + 80 	imes 11 + 20 	imes 90 = 5,540$$

Question 7

What does the GDP deflator measure?

Accepted Answer

The average price level of all final goods and services produced in the economy.

Question 8

Which formula correctly calculates the GDP deflator?

Accepted Answer

$$\frac{	ext{Nominal GDP}}{	ext{Real GDP}} 	imes 100$$

Question 9

If the nominal GDP in 2025 is $$7,800 and the real GDP (base year 2017) is 5$$,540, what is the GDP deflator for 2025?

Accepted Answer

$$\frac{7,800}{5,540} 	imes 100 = 140.8$$

Question 10

What does a GDP deflator value of 140.8 indicate?

Accepted Answer

Prices are 40.8% higher than in the base year, and the overall price level has increased.

Question 11

If the GDP deflator increases from 100 to 140.8 over several years, what does this tell us about inflation?

Accepted Answer

The price level has increased by 40.8% since the base year.

Question 12

Which of the following is NOT a reason why real GDP might increase?

Accepted Answer

Higher prices due to inflation.

Question 13

Why can the introduction of new goods distort simple real-GDP calculations?

Accepted Answer

New goods can change the relative prices and quantities, making comparisons across years less accurate.

Question 14

Which statement about the base year in real GDP calculations is correct?

Accepted Answer

The base year is arbitrary and can be chosen by the analyst.

Question 15

If the GDP deflator in 2025 is 140.8 and in 2017 is 100, what is the average annual inflation rate over this period?

Accepted Answer

$$\frac{140.8 - 100}{100} \div 8 	imes 100 = 5.1\%$$

Question 16

Which of the following is a key takeaway about the GDP deflator?

Accepted Answer

It is a broad measure of inflation across the entire economy.

Question 17

What is the main advantage of chain weighting in real GDP calculations?

Accepted Answer

It improves real-GDP accuracy by updating the price base each year.

Question 18

If nominal GDP increases but real GDP remains constant, what can be inferred?

Accepted Answer

Prices have increased due to inflation.

Question 19

Which of the following best explains why the GDP deflator is considered a 'broad inflation gauge'?

Accepted Answer

It measures the change in prices of all final goods and services produced domestically.
