Q: Suppose a country produces only three goods: apples, bread, and computers. In 2022, the quantities produced and prices are as follows: 100 apples at $$1 each, 50 loaves of bread at 2 $$each, and 10 computers at $$500 each. In 2023, the quantities are the same, but prices rise to 1.10 $$for apples, $$2.20 for bread, and 550 $$for computers. What is the GDP deflator for 2023, using 2022 as the base year?

$$GDP\ deflator = \frac{Nominal\ GDP}{Real\ GDP} \times 100 = \frac{(1.10 \times 100) + (2.20 \times 50) + (550 \times 10)}{(1 \times 100) + (2 \times 50) + (500 \times 10)} \times 100 = \frac{110 + 110 + 5500}{100 + 100 + 5000} \times 100 = \frac{5720}{5200} \times 100 = 110$$

Q: A country has a population of 100 million people. 60 million are in the labor force, 54 million are employed, and 6 million are unemployed. What is the unemployment rate?

$$Unemployment\ rate = \frac{Unemployed}{Labor\ force} \times 100 = \frac{6}{60} \times 100 = 10\%$$

Q: If nominal GDP in 2022 is $$5 trillion and real GDP in 2022 (using 2015 as the base year) is 4 $$trillion, what is the GDP deflator for 2022?

$$GDP\ deflator = \frac{Nominal\ GDP}{Real\ GDP} \times 100 = \frac{5}{4} \times 100 = 125$$

Question 1

Suppose a country produces only three goods: apples, bread, and computers. In 2022, the quantities produced and prices are as follows: 100 apples at $$1 each, 50 loaves of bread at 2 $$each, and 10 computers at $$500 each. In 2023, the quantities are the same, but prices rise to 1.10 $$for apples, $$2.20 for bread, and 550 $$for computers. What is the GDP deflator for 2023, using 2022 as the base year?

Accepted Answer

$$GDP\ deflator = \frac{Nominal\ GDP}{Real\ GDP} 	imes 100 = \frac{(1.10 	imes 100) + (2.20 	imes 50) + (550 	imes 10)}{(1 	imes 100) + (2 	imes 50) + (500 	imes 10)} 	imes 100 = \frac{110 + 110 + 5500}{100 + 100 + 5000} 	imes 100 = \frac{5720}{5200} 	imes 100 = 110$$

Question 2

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

Accepted Answer

Transfer payments such as unemployment benefits

Question 3

If the Consumer Price Index (CPI) was 120 last year and is 126 this year, what is the inflation rate for this year?

Accepted Answer

$$Inflation\ rate = \frac{CPI_{this\ year} - CPI_{last\ year}}{CPI_{last\ year}} 	imes 100 = \frac{126 - 120}{120} 	imes 100 = 5\%$$

Question 4

Which of the following best describes 'creative destruction' in the context of economic growth?

Accepted Answer

The process by which new innovations replace outdated industries and methods, leading to economic progress

Question 5

A country has a population of 100 million people. 60 million are in the labor force, 54 million are employed, and 6 million are unemployed. What is the unemployment rate?

Accepted Answer

$$Unemployment\ rate = \frac{Unemployed}{Labor\ force} 	imes 100 = \frac{6}{60} 	imes 100 = 10\%$$

Question 6

Which of the following is an example of structural unemployment?

Accepted Answer

A factory worker loses their job because their skills are no longer needed due to automation

Question 7

If nominal GDP in 2022 is $$5 trillion and real GDP in 2022 (using 2015 as the base year) is 4 $$trillion, what is the GDP deflator for 2022?

Accepted Answer

$$GDP\ deflator = \frac{Nominal\ GDP}{Real\ GDP} 	imes 100 = \frac{5}{4} 	imes 100 = 125$$

Question 8

Which of the following is a shortcoming of using GDP as a measure of economic well-being?

Accepted Answer

GDP does not account for the distribution of income among residents of a country

Question 9

If the real interest rate is 3% and the inflation rate is 2%, what is the nominal interest rate?

Accepted Answer

$$Nominal\ interest\ rate = Real\ interest\ rate + Inflation\ rate = 3\% + 2\% = 5\%$$

Question 10

Which of the following policies is most likely to promote long-term economic growth according to new growth theory?

Accepted Answer

Investing in research and development to foster technological innovation

Question 11

A country has the following data (in billions): Consumption = $$500, Investment = 200$$, Government Purchases = $$300, Exports = 100$$, Imports = $150. What is the country's GDP using the expenditure approach?

Accepted Answer

$$GDP = C + I + G + (X - M) = 500 + 200 + 300 + (100 - 150) = 500 + 200 + 300 - 50 = 950$$

Question 12

Which of the following best describes the 'catch-up' or 'convergence' theory in economic growth?

Accepted Answer

Poorer countries can grow faster than richer ones if they adopt the right policies and technologies

Question 13

Accepted Answer

Physical machinery used in production

Question 14

If a country’s exports are $$400 billion and its imports are 500 $$billion, what is the value of net exports, and how does it affect GDP?

Accepted Answer

$$Net\ exports = Exports - Imports = 400 - 500 = -100\ billion. $$This negative value reduces GDP.

Question 15

A person who has stopped looking for a job because they believe no jobs are available

Question 16

Which of the following would be counted as investment in the calculation of GDP?

Accepted Answer

A business purchasing new equipment for its factory

Question 17

Accepted Answer

$$Labor\ force\ participation\ rate = \frac{80}{100} 	imes 100 = 80\%$$

Question 18
