Lesson 13a: Wage Determination: Labor Markets

Key Problems

Monopsony - Table

Minimum Wage - Traditional Model

Minimum Wage in a Monopsony Model

Minimum Wage and Price Elasticity of Demand for Labor Model

 

Monopsony - Table

Use the data above to calculate (1) the quantity of labor this firm will hire to maximize its profits, and (2) the allocatively efficient quantity of labor to hire.

Assume the firm hires labor, its only variable resource, under monopsonistic conditions and sells its product under competitive conditions.

Minimum Wage - Traditional Model

 

MULTIPLE CHOICE:

1. In the labor market shown above, with NO MINIMUM WAGE, the equilibrium quantity employed will be:

A. 0B. 10C. 12D. 14

2. In the labor market shown above, if the minimum wage is set at Wm, the equilibrium quantity employed will be:

A. 0B. 10 C. 12D. 14

3. In the labor market shown above, the allocatively efficient quantity to employ is:

A. 0B. 10C. 12D. 14

4. In the labor market shown above, if the minimum wage is set at Wm, the amount of unemployment created by the minimum wage is:

A. 2B. 4C. 12D. 14

5. In the labor market shown above, if the minimum wage is set at Wm, it will cause:

A. Employment to increase from 10 to 12
B. Employment to increase from 12 to 14
C. Employment to decrease from 14 to 12
D. Employment to decrease from 12 to 10

 

Minimum Wage in a Monopsony Model

MULTIPLE CHOICE:

1. Use the figure above to answer this question., If the minimum wage is set at Wmin, what will happen to employment in this monopsonistic labor market?

A. Employment will decrease
B. Employment will increase
C. Employment will stay the same
D. Employment may increase but usually it tends to stay the same

2. Use the figure above to answer this question. Senator Approximire opposes a proposal that the monopsonist pay a minimum wage of at least Wmin stating "Even if the labor market is monopsonistic, economic theory unambiguously demonstrates that imposing a minimum wage causes employment to fall." Senator Approxmire is:

A. Correct because the law of demand states that as the wage rises, the firm demands less labor

B. Incorrect because the monopsonist would offer a wage of WA, which is higher than Wmin, and maintain its employment level at L1

C. Incorrect because the monopsonist's effective MRC curve becomes ABCD, which means that it will choose to hire more workers, from L1 to L2.

D. Correct because the graph indicates that at the wage of Wmin, the monopsonist would not make a profit from hiring labor and so would not hire any at all.

 3. Use the figure above to answer this question,. If the minimum wage is set at Wmin then:

A. this labor market will become less efficient
B. this labor market will become more efficient

4. Use the figure above to answer this question. The allocatively efficient quantity of labor is:

A. L1 B. L2 C. L3

 

Minimum Wage and Price Elasticity of Demand for Labor Model
(Jobs are lost, but do the poor gain more income?)

MULTIPLE CHOICE:

1. Use the figure above to answer this question. If the minimum wage is increases from Wmin1 to Wmin2 what will happen to the income received by minimum wage workers in Labor Market 1?

A.decrease from 0BCD to 0ADF
B.decrease from 0ADF to 0BCD
C.increase from 0ADF to 0BCE
D.increase from 0BCE to 0ADF

 2. Use the figure above to answer this question. If the minimum wage is increases from Wmin1 to Wmin2 what will happen to the income received by minimum wage workers?

A. Total incomes decrease for minimum wage workers in Labor Market 1 because the demand for labor is elastic

B. Total incomes increase for minimum wage workers in Labor Market 2 because the demand for labor is elastic

C. Total incomes increase for minimum wage workers in Labor Market 1 because the demand for labor is inelastic

D. Total incomes decrease for minimum wage workers in Labor Market 2 because the demand for labor is inelastic

 3. Use the figure above to answer this question. In which labor market is the demand for labor less price (wage) elastic?

A. Labor Market 1
B. Labor Market 2

4. Use the figure above to answer this question. Which of the following is correct if the minimum wage is increased from Wmin1 to Wmin2 ?

A. Total revenues increase in Labor Market 1 and decrease in Labor Market 2
B. Total revenues decrease in Labor Market 1 and increase in Labor Market 2
C. Total revenues increase in both labor markets
D. Total revenues decrease in both labor markets

5. So, even if raising the minimum wage causes more unemployment, does such an increase help minimum wage workers?

A.Yes
B. No
C. It depends on the price elasticity of demand for low skilled labor
