Document Summary

Chapter 14: the markets for factors of production. No control over wage: determined by market. Value of the marginal product of labour, vmpl- a worker"s contribution to tr is their mp (what they add to total output) times p. Vmpl when labour in the sr because the market p of the good is constant. Firm will only hire if their contribution > her cost to the firm. Firm will hire up until point (where profit is maximized) W: mc of the last hired worker is their addition to tc (their wage) Vmpl: mr of the laster worker hired is their addition to tr. P*mpl : firm will hire where mrl = mcl profits maximized. Ex: brady"s bottles sells plastic bottles for sh. 50. Labour is paid /hr: brady will hire until w = vmpl (6th worker, wouldn"t hire the 7th worker because they add to their tr but costs him .

1. Which of the following is characteristic of the marginal revenue product schedule for a resource?

a. It approximates the firm's demand curve for the resource.

b. It measures the change in total revenue resulting from employing an additional unit of the resource.

c. It is determined by multiplying the marginal product of the resource by the marginal revenue of the good produced.

d. All of these are true.

2. Assume Ajax Company employs 100 workers and the total revenue is $400,000 per week. When Ajax Company employs 101 workers, the total revenue is $405,000. The marginal revenue product of the 101st worker is:

a. $40,000.

b. $5,000.

c. $405,000.

d. none of these.

3. The optimal number of workers to be hired by a firm operating in a competitive labour market is where:

a. P = MRP.

b. MP = MRP.

c. MRP = w.

d. P = w.

Assume that the firm only uses labor as a resource in production and is hiring workers in a purely competitive labor market. In other words, the firm can hire as many workers as it wishes without affecting the equilibrium wage rate.

Units of Labor (L)	Total Product (Q)	Product Price (P)	Total Revenue (TR)	Marginal Revenue Product (MRP)
0	0	$2.20	$0	---
1	15	$2.00	$30	$30
2	28	$1.80
3	39	$1.60
4	48	$1.40
5	55	$1.20
6	60	$1.10

a. Is the firm selling its product in a purely competitive market or an imperfectly competitive market?

b. Fill out both the TR and MRP columns with the correct values.

c. Suppose the wage rate is $11.00 per worker. How many workers should be employed, in order to maximize profits?

d. If the firm hires the optimum number of workers, what is its total profit?

1. A firm's supply curve for labor: A) is vertical for a firm in perfect competition. B) is the same thing as the MRPL for a firm in perfect competition. C) and the firm's MRPL will determine the profit-maximizing quantity of labor hired by the firm in perfect competition. D) is the same as its demand curve for labor. 2. The wage paid by a firm buying labor in a perfectly competitive market: A) is greater than the market wage. B) is less than the market wage. C) is equal to the market wage. D) increases with the quantity of labor hired. 3. A lower wage: A) has an income effect but not a substitution effect on the quantity of labor supplied. B) means a higher income for any given level of labor supplied. C) has an income effect which is always negative with respect to the quantity of labor supplied. D) has an income effect which is always positive with respect to the quantity of labor supplied. 4. In perfect competition where P is the price of output: A) MRPL = MPL x P. B) MRPL/MPL = PL. C) MRP/P = MPK. D) MRPL x P = MPL. 5. The net present value (NPV) of an activity or project is: A) equal to the future value of all the revenues minus the present value of all the costs associated with it. B) equal to the present value of all the revenues minus the present values of all the costs associated with it. C) equal to the present value of all the revenues minus the future values of all the costs associated with it. D) equal to the future values of all the revenues minus the future values of all the costs associated with it. 6. The condition for hiring factors of production- that is, where MFC = MRP- is analogous to the profit-maximizing output condition: A) TR = TC. B) MR = MC. C) AR = ATC. D) P = MR. 7. A firm should use less of a factor of production if: A) MRP > MFC. B) MRP = MFC C) (MR x MP) < MFC D) MRP < (MP x MR)
