CHAPTER 16
The Demand for Resources
A. Short-Answer, Essays, and Problems
1. What are four significant reasons for studying resource pricing?
2. The theory of resource pricing is sometimes referred to by economists as the theory of income distribution.
Why?
3. Why aren’t the tools of product market analysis directly applicable to the resource market?
4. How do the factors determining resource demand differ from those in the product market?
5. Why is the demand for resources called a “derived” demand? On what two factors does the strength of the
demand for resources depend? How are these two factors related?
6. What are the two key factors that determine the strength of demand? How do they determine whether a
good is in high demand or low demand?
7. What is the profit-maximizing condition for the use of a resource?
8. Why is the marginal revenue product schedule a demand schedule for the individual firm in a purely
competitive resource market and selling output in a purely competitive product market?

9. The table below shows the total production a firm will be able to obtain if it employs varying amounts of
resource X while the amounts of the other resources the firm employs remain constant. Compute the
marginal product of each of the seven units of resource X and enter these figures in the table. Assume the
product the firm produces sells in the market for $3.00 per unit. Compute the total revenue of the firm at
each of the eight levels of output and the marginal revenue product of each of the seven units of resource X.
Enter these figures in the table below.

(c) Suppose the equilibrium wage is $21. What is the quantity of workers that will be employed?
20. (Consider This) How is marginal revenue product reflected in “winner-take-all” markets such as in the music
industry?
21. What is the difference between a change in resource demand and a change in the quantity of a resource
demanded? What factors contribute to a change in resource demand or a change in the quantity of a resource
demanded?
22. How will a change in productivity change the demand for a resource? What three factors will affect
productivity?
23. Compare the factors that will cause shifts in the downsloping resource demand and product demand curves.
24. Assume that labor and capital are substitutes in production. If there is an increase in the price of capital,
how can this lead to either an increase or decrease in the demand for labor?
25. Why is the effect of a change in price of a substitute good potentially ambiguous?
26. Does it matter whether capital and labor are substitutes or complements when figuring out what will
happen to the demand for labor if the price of capital increases? Explain.
27. Compare and explain the significance of the substitution and output effects as they apply to resource
pricing. What relationship, if any, do they bear to the income and substitution effects discussed in
connection with product demand?
page-pf9
28. Indicate how the following events will shift the firm’s demand curve for labor: increase it (I); decrease it
(D); keep it the same (S).

___ The wage rate increases.
___ The demand for the product that labor produces decreases.
___ The wage rate decreases.
___ Absenteeism reduces labor’s productivity.
___ The price of labor-saving machinery is reduced and the substitution effect is greater than the output
effect.
29. What are examples of the fastest growing occupations in percentage terms expected to be from 20142024?
What economic principle of resource pricing best explains these trends?
30. What are three examples of occupations that are expected to experience a rapid decline in employment
from 20142024? Why are these occupations likely to experience this decline?
31. What will be the elasticity of resource demand in the following cases?
(a) unit wages rise by 10% and the number of employed workers falls by 5%
(b) unit wages rise by 4% and the number of employed workers falls by 6%
(c) unit wages rise by 3% and the number of employed workers falls by 3%
32. Compare the factors that explain the elasticity of resource and product demand.
33. What effect, if any, will each of the following have upon the elasticity or the location of the demand curve
for resource J that is being used in the production of commodity X? If there is uncertainty as to the precise
effect, explain the sources of that uncertainty.
(a) A decline in the demand for product X.
(b) An increase in the price of Y, a substitute product for X.
(c) A decline in the price of substitute resource K.
(d) A decline in the number of available resources that are substitutable for J in the production of X.
(e) An increase in the price of complementary resource L.
(f) An increase in the elasticity of demand for product X due to an increase in the number of sellers in the
market.
34. Explain briefly and concisely the meaning and significance of the following equation:
35. A firm combines two resources, X and Y, to produce an output level Q in a purely competitive market. The
cost of a unit of X is $15 and the cost of a unit of Y is $8. The marginal product of X is 30 units and the
marginal product of Y is currently 24 units at output level Q. What would you recommend that the firm do
given this resource combination?
36. A firm combines two resources, X and Y, to produce an output level Q in a purely competitive market. The
cost of a unit of X is $20 and the cost of a unit of Y is $4. The marginal product of X is 100 units and the

14. In the table below are the marginal product data for resource Y. Assume that the quantities of other
resources employed by the firm remain constant. Compute the total product (output) of the firm for each of
the seven quantities of resource Y employed and enter these figures in the table. Assume that the firm sells
its output in an imperfectly competitive market and that the prices at which it can sell its product are those
given in the table. Compute and enter in the table total revenue and the marginal revenue product for each
of the seven units of resource Y.
