Summary
47
Marginal revenue product (MRP) is determined by a worker’s contribution to a firm’s total revenue. Algebraically, the MRP equals the price of the product times the worker’s marginal product (MP).
48
The demand curve for labor is the curve showing the quantities of labor a firm is willing to hire at different prices of labor. The marginal revenue product (MRP) of labor curve is the firm’s demand curve for labor. Summing individual demand for labor curves gives the market demand curve for labor.

5Q
50
Derived demand means that a firm demands labor because labor is productive. Changes in consumer demand for a product cause changes in demand for labor and for other resources used to make the product.
51
The supply curve of labor is the curve showing the quantities of workers willing to work at different prices of labor. The market supply curve of labor is derived by adding the individual supply curves of labor.

Human capital is the accumulated people make in education, training, experience, and health in order to make themselves more productive. One explanation for earnings differences is differences in human capital.
54
Collective bargaining is the process through which a union and management negotiate a labor contract.
55
Monopsony is a labor market in which a single firm hires labor. Because the monopsonist faces the industry supply curve of labor and each worker is paid the same wage, changes in total wage cost exceed the wage rate necessary to hire each additional worker. As a result, the marginal factor cost (MFC) of labor curve lies above the supply curve of labor.
56
The monopsonist’s wage rate and quantity of labor are determined where the MFC equals MRP . Since at this point the worker’s MRP is greater than the wage paid, the monopsonist exploits the workers.

1. Marginal revenue product measures the increase in a. output resulting from one more unit of
labor.b. TR resulting from one more unit of
output.c. revenue per unit from one more unit of
output.d. total revenue resulting from one more
unit of labor.D. MRP is the increase in total revenue to a firm resulting from hiring an additional unit of labor or other variable resource.
60
2. Troll Corporation sells dolls for $10.00 each in a market that is perfectly competitive. Increasing the number of workers from 100 to 101 would cause output to rise from 500 to 510 dolls per day. Troll should hire the 101st worker only when the wage is a. $100 or less per day.b. more than $100 per day.c. $5.10 or less per day.d. none of the above.
A. Under perfect competition, the firm hires workers until the MRP equals the wage rate. MRP equals $10 x MP (510 - 500) = $100.
61
3. Derived demand for labor depends on the a. cost of factors of production used in the
product.b. market supply curve of labor.c. consumer demand for the final goods
produced by labor.d. firm’s total revenue less economic profit.
C. If consumers do not purchase goods, there is no MRP and no workers are hired.
62
4. If demand for a product falls, the demand curve for labor used to produce the product will shift a. leftward.b. rightward.c. upward.d. downward.
A. If consumers demand for a product decreases and supply remains the constant, the price of the product falls and the MRP (P x MP) decreases.
63
5. The owner of a restaurant will hire waiters if the a. additional labor’s pay is close to the
minimum wage .b. marginal product is at the maximum.c. additional work of the employees adds
more to total revenue than to costs.d. waiters do not belong to a union.
C. If MRP exceeds the wage rate paid waiters, it is profitable for the restaurant to hire more waiters.
64
6. In a perfectly competitive market, the demand curve for labor a. slopes upward.b. slopes downward because of
diminishing marginal productivity.c. is perfectly elastic at the equilibrium
wage rate.d. is described by all of the above.
B. As output expands in the short run, a fixed factor results in diminishing returns causing MP to decrease. Correspondingly, MRP decreases.
65
7. A union can influence the equilibrium wage rate by a. featherbedding.b. requiring longer apprenticeships.c. favoring trade restrictions on
foreign products.d. all of the above.e. none of the above.
D. Featherbedding and trade protectionism increase the demand for labor. Requiring longer apprenticeship decreases the demand for labor.
66
8. In which of the following market structures is the firm not a price taker in the factor market?a. Oligopoly.b. Monopsony.c. Monopoly.d. Perfect competition.
B. Monopsony is a labor market in which a single firm hires labor. For example, the “company town” where everyone works for the same employer.
67
9. The extra cost of obtaining each additional unit of a factor of production is called the marginal a. physical product.b. revenue product.c. factor cost.d. implicit cost.
C. The assumption of MFC is that the firm must pay a higher wage to each additional worker as well as to all previously hired workers.
68
10. A monopsonist’s marginal factor cost curve lies above its supply curve because the firm must a. increase the price of its product to sell
more.b. lower the price of its product to sell more.c. increase the wage rate to hire more labor.d. lower the wage rate to hire more labor.C. The monopsonist can hire an
additional worker only by raising the wage rate for all workers. Therefore, the MFC exceeds the wage rate along the labor supply curve.
69
11. In order to maximize profits, a monopsonist will hire the quantity of labor to the point where the marginal factor cost is equal to a. marginal physical product.b. marginal revenue product.c. total revenue product.d. any of the above.
B. The MRP curve is the contribution of each worker to total revenue and MFC the addition to total cost. When MRP > MFC, the firm hires more workers.

12. BigBiz, a local monopolist, currently hires 50 workers and pays them $6 per hour. To attract an additional worker to its labor force, BigBiz would have to raise the wage rate to $6.25 per hour. What is BigBiz’s marginal factor cost?a. $6.25 per hour.b. $12.50 per hour. c. $18.75 per hour.d. $20.00 per hour.
C. Its total cost would increase by $18.75 to hire that additional worker (25 x 50 + 6.25).
72
13. Suppose a firm can hire 100 workers at $8.00 per hour, but must pay $8.05 per hour to hire 101 workers. Marginal factor cost (MFC) for the 101st worker is approximately equal to a. $8.00.b. $8.05.c. $13.05.d. $13.00.
C. The firm’s total cost would increase $13.05 to hire the 101st worker (.05 x 100 + 8.05).
73
14. A monopsonist in equilibrium has a marginal revenue product of $10 per worker hour. Its equilibrium wage rate must be a. less than $10.b. equal to $10.c. greater than $10.d. equal to $5.
A. Because of its monopoly in the labor market, a monopsony hires fewer workers and pays a lower wage than a firm in a competitive labor market.
