Suppose a firm hires both labor (L) and capital (C) under purely competitive
conditions. The price of labor is PL, and that of capital is PC. The marginal product of labor
is MPL, and that of capital is MPC. The firm sells its product competitively at a price of PX.
Which of the following must pertain if the firm is to minimize the cost of
producing any
output?
A.
MPC = MPL = PX

conditions. The price of labor is PL, and that of capital is PC. The marginal product of labor
is MPL, and that of capital is MPC. The firm sells its product competitively at a price of PX.

Refer to the diagram. If a firm produces output Q1 at a unit cost of c, then the
A.
firm is operating in a purely competitive industry.
131.
Refer to the diagram. If a firm produces output Q1 at a unit cost of b, then the
D.
firm has achieved minimum efficient scale.
132.
Refer to the diagram. The production of Q1 units of output at an average cost of a

The marginal productivity theory of income distribution suggests that
A. government should subsidize the most productive workers through a system of transfer

incentives.

True / False Questions
142.
The marginal revenue product curve of a purely competitive seller declines solely
because of the law of diminishing returns.
143.
Producers should hire resources until the total output of each is equal.
16-70
144.
It will be profitable for a firm to hire additional units of any resource up to the point at
which its MRP is equal to its MRC.
145.
The more elastic the demand for a product, the less elastic will be the demand for the
resources employed in producing it.
146.
The demand for a resource depends on its productivity and the market value of the
product it is producing.
147.
If two resources are complementary, a decrease in the price of one will reduce the
demand for the other.

FALSE
148.
Other things equal, the less competitive the market in which a firm sells its product, the
less elastic will be its resource demand curve.
149.
If the substitution effect outweighs the output effect, an increase in the price of a
substitute resource will increase the demand for labor.
150.
The demand for labor is a derived demand, whereas the demand for capital is not.

The MRP of labor curve is the firm's labor demand curve.
152.
Marginal revenue product (MRP) is the change in total product (total output) associated

Elasticity of resource demand is measured by dividing "percentage change in resource
price" by "percentage change in resource quantity."
155.
An increase in the price of capital will reduce the demand for labor if capital and labor
are complementary resources.
156.
The marginal productivity theory of income distribution holds that all resources are paid
according to their marginal contribution to society's output.
157.
Hiring the least-costly combination of resources ensures that profits will be maximized.
