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).
![Page 46: 1 Chapter 11 Labor Markets Key Concepts Key Concepts Summary Summary Practice Quiz Internet Exercises Internet Exercises ©2002 South-Western College Publishing.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649dc55503460f94ab9260/html5/thumbnails/46.jpg)

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.

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.

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.

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.

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.

output.c. revenue per unit from one more unit

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.

diminishing marginal productivity.
c. is perfectly elastic at the equilibrium wage rate.
d. 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.

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.
