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?

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

Question 1

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

Accepted Answer

There is a movement along the demand curve.

Question 2

If the government sets a minimum wage above the equilibrium wage, what is the most likely result in the labor market?

Accepted Answer

Unemployment will increase due to a surplus of labor.

Question 3

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

Accepted Answer

Nominal values are measured in current prices, while real values are adjusted for inflation.

Question 4

Given the following data for a country in a given year: Consumption = $$500, Investment = 200$$, Government Spending = $$300, Net Exports = -50. $$What is the GDP using the expenditure approach?

Accepted Answer

$950

Question 5

Which formula correctly calculates the unemployment rate?

Accepted Answer

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

Question 6

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

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

Question 7

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 8

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

Accepted Answer

Real GDP remained unchanged.

Question 9

Which of the following best explains why unions can lead to unemployment?

Accepted Answer

Unions can negotiate wages above the equilibrium wage, causing a surplus of labor.

Question 10

If the labor force participation rate is calculated as $$\frac{	ext{Labor Force}}{	ext{Working Age Population}} 	imes 100$$, which of the following scenarios would increase the participation rate?

Accepted Answer

An increase in the number of people actively seeking work.

Question 11

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

Accepted Answer

Purchases of used goods.

Question 12

If a market is not in equilibrium, what will typically happen?

Accepted Answer

Market forces will push the price and quantity toward equilibrium.

Question 13

Suppose the supply curve for a product shifts to the right. What is the likely effect on equilibrium price and quantity, all else equal?

Accepted Answer

Equilibrium price decreases, equilibrium quantity increases.

Question 14

Which of the following best describes the value-added approach to calculating GDP?

Accepted Answer

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

Question 15

If the actual wage in a labor market is above the equilibrium wage, what is the result?

Accepted Answer

There will be a surplus of labor, leading to unemployment.

Question 16

Which of the following is a reason why it is important to use real GDP rather than nominal GDP when comparing economic output across years?

Accepted Answer

Real GDP adjusts for changes in the price level, allowing for meaningful comparisons over time.

Question 17

If the labor force is 200 million and the number of unemployed is 10 million, what is the unemployment rate?

Accepted Answer

$$\frac{10}{200} 	imes 100 = 5\%$$

Question 18

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

Accepted Answer

A change in consumer income.

Question 19

If the CPI in 2020 is 150 and in 2021 is 165, what is the inflation rate from 2020 to 2021?

Accepted Answer

$$\frac{165 - 150}{150} 	imes 100 = 10\%$$

Question 20

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