Practice Questions 6

Goal:

- Review basic concepts: Marginal Physical Product, Marginal Revenue Product, Marginal Labor cost.
- Learn how to use demand and supply curves to determine the equilibrium wage and employment in a competitive labor market.
- Understand the impact of Minimum Wage Law, and how income and substitution effects influence the supply curve of labor.

1. Tony runs a small company, Bearpaw Boots, that manufactures hiking boots. Table 1 shows output per month for different quantities of labor.

a. Fill in the third column by using the data in the second column to compute the marginal physical product of each additional worker.

b. Tony can sell boots for $60 a pair. As Tony has a small firm, the price of boots is unaffected by the quantity that he sells. Fill in the fourth column by computing the marginal revenue products of each worker.

c. Assume Tony sells his product in a perfectly competitive market and hires in a perfectly competitive labor market. How many workers will Tony employ if monthly wages are $1800?

d. What will be Tony's profits given his hiring decision in (c)?

2. Fill in the following blanks.

In a competitive labor market,    (1)     and    (2)  will be determined by the interaction of the demand and the supply of labor curves. The supply of labor comes from individual decisions   to work. Individual decisions to supply work are simultaneously decisions to forgo leisure. Thus, a decision  to supply  less labor  is simultaneously  a decision  to demand  more  (3) . At higher wages, the same number of  working hours will mean a larger income. If leisure is not an inferior  good, people  are  apt  to  demand  (4) (more/less)  leisure  as  their  income  increases.  This suggests that the supply of labor might    (5)    (increase/decrease) as wages increase.   This is    called     (6)      (income/substitution) effect of higher wages.

Higher wages also increase the opportunity cost of an hour of leisure. As a result we expect that as wages increase, the substitution effect will lead people   to work (7)                    (more/less). The ultimate effect of increased wages comes from the sum of the income and substitution effects. Statistical evidence suggests that at low wages the     (8)                                                                                effect predominates and labor supply     (9)    with an increase in wages, while at high wages the two effects tend to     (10)            (enhance/offset) each other.

In some cases, the market determination of wages and employment is affected by a legal floor on wages  rates,  or a                                    (11)       rate.  To  be  effective,  the  minimum  wage must be    (12)        (higher/lower) than the market wage. Imposing a minimum  wage will                                 (13)    (increase/decrease) the volume of employment as firms move upward and to the left along their demand curves for labor. At the same time the promise of higher wages is apt to   increase the                                                      (14)       (demand/supply) of labor. Minimum wage laws affect primarily (15) (skilled/unskilled) labor markets. A major noncompetitive feature in many skilled labor markets is the existence of labor                      (16)                                                                               .

3. Suppose that the marginal revenue product schedule or demand for labor for one of 100 identical and perfectly competitive firms is given by column (1) and (2) of table 3, and the market supply schedule of labor is given by columns (1) and (3).

a. Find the market demand schedule for labor and the equilibrium wage rate.

b. How much labor should the firm hire to maximize its total profits?

c. Graph the results to part (a) and (b).
