Accepted Answer

5 workers

Question 5

Which equation correctly represents the Marginal Revenue Product of Labor (MRPL) in a competitive market?

Accepted Answer

$$	ext{MRPL} = 	ext{Marginal Product of Labor} 	imes 	ext{Price of the good}$$

Question 6

What happens to the demand for labor if the price of a firm's output increases?

Accepted Answer

30 hours

Question 10

Which effect describes how a person responds to an increasing opportunity cost of leisure by reducing leisure and increasing labor supplied?

Accepted Answer

Substitution effect

Question 11

At high wage rates, which effect dominates and causes the labor supply curve to bend backward?

Accepted Answer

Income effect

Question 12

What does the market supply curve of labor represent?

Accepted Answer

The horizontal sum of individual labor supply curves.

Question 13

Refer to the third image. What does the intersection of the supply and demand curves represent in a labor market?

Accepted Answer

The equilibrium wage rate and quantity of labor employed.

Question 14

Why do surgeons earn much higher wages than fast-food workers, according to labor market theory?

Accepted Answer

Surgeons have higher reservation wages due to the cost of acquiring human capital.

Question 15

Accepted Answer

The demand for bakery workers decreases.

Question 17

If the market for bricks is perfectly competitive and each pound sells for $20, what is the value of the marginal product of the fourth worker if the marginal product is 2 pounds?

Accepted Answer

$40

Question 18

Which of the following best explains persistent wage differentials between occupations?

Accepted Answer

Differences in the cost of acquiring human capital and reservation wages.

Question 19

If the wage rate rises above a person's reservation wage, what happens to the quantity of labor supplied?

Accepted Answer

It increases.

Question 20

Which formula would you use to calculate the marginal product of labor?

Accepted Answer
