Q: Which formula correctly calculates the unemployment rate?

$ \text{Unemployment Rate} = \frac{\text{Number of Unemployed}}{\text{Labor Force}} \times 100 $

Q: If the Consumer Price Index (CPI) in the base year is 100 and in the current year is 120, what is the inflation rate between the two years?

$ \text{Inflation Rate} = \frac{120 - 100}{100} \times 100 = 20\% $

Q: A country has a labor force of 200 million people, of which 190 million are employed. What is the unemployment rate?

$ \frac{200 - 190}{200} \times 100 = 5\% $

Question 1

Suppose the price of a product increases. According to the distinction between a movement and a shift in demand, what will happen to the demand curve?

Accepted Answer

There will be a movement along the demand curve.

Question 2

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 3

If the equilibrium price of a good is $10 and the government sets a minimum price (price floor) of $12, what is the likely result in the market?

Accepted Answer

A surplus will occur because quantity supplied exceeds quantity demanded at $12.

Question 4

Which formula correctly calculates the unemployment rate?

Accepted Answer

$ 	ext{Unemployment Rate} = \frac{	ext{Number of Unemployed}}{	ext{Labor Force}} 	imes 100 $

Question 5

Why is it important to use the GDP deflator when comparing GDP across years?

Accepted Answer

It adjusts for changes in the price level, allowing for comparison of real output over time.

Question 6

Which of the following is NOT a reason why unemployment can persist even when there are job vacancies?

Accepted Answer

The actual wage is below the equilibrium wage.

Question 7

If the Consumer Price Index (CPI) in the base year is 100 and in the current year is 120, what is the inflation rate between the two years?

Accepted Answer

$ 	ext{Inflation Rate} = \frac{120 - 100}{100} 	imes 100 = 20\% $

Question 8

Which of the following best describes the value-added method for calculating GDP?

Accepted Answer

It sums the value added at each stage of production for all goods and services.

Question 9

A country has a labor force of 200 million people, of which 190 million are employed. What is the unemployment rate?

Accepted Answer

$ \frac{200 - 190}{200} 	imes 100 = 5\% $

Question 10

Which of the following is an example of a shift in the supply curve?

Accepted Answer

A technological innovation reduces production costs for firms.

Question 11

If the labor force participation rate increases, what does this indicate about the economy?

Accepted Answer

A higher proportion of the working-age population is either employed or actively seeking work.

Question 12

Which of the following is a shortcoming of using nominal GDP to compare economic output across years?

Accepted Answer

It does not account for changes in the price level (inflation or deflation).

Question 13

Suppose the government introduces a new tax on labor income. What is the likely effect on the labor market equilibrium?

Accepted Answer

The equilibrium wage will decrease and the equilibrium quantity of labor will fall.

Question 14

Which of the following best explains why the CPI may overstate the true cost of living?

Accepted Answer

It does not account for consumers substituting cheaper goods when prices change.

Question 15

If the actual wage in a labor market is set above the equilibrium wage, what is the most likely outcome?

Accepted Answer

Unemployment will occur because the quantity of labor supplied exceeds the quantity demanded.

Question 16

Which of the following is the correct formula for the GDP deflator?

Accepted Answer

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

Question 17

A country’s nominal GDP increased from $1 trillion to $1.1 trillion, while its GDP deflator increased from 100 to 110. What happened to real GDP?

Accepted Answer

Real GDP remained unchanged.

Question 18

Which of the following is an example of frictional unemployment?

Accepted Answer

A recent college graduate is searching for their first job.

Question 19

If the price of a substitute good increases, what is the likely effect on the demand for the original good?

Accepted Answer

The demand for the original good will increase (shift to the right).

Question 20

Which of the following best describes the labor force participation rate?

Accepted Answer

$ 	ext{Labor Force Participation Rate} = \frac{	ext{Labor Force}}{	ext{Working-Age Population}} 	imes 100 $
