1. If marginal cost is less than average total cost, then:

A. average total cost is increasing with output.
B. average total cost is decreasing with output.
C. average variable cost is increasing with output.
D. average variable cost is decreasing with output.

 

2.  The law of diminishing marginal productivity:

A. states that as more and more of a variable input is added to an existing fixed input, after some point the additional output one gets from the additional input will fall.

B. states that as more and more of a variable input is added to an existing fixed input, after some point the additional output one gets from the additional input will rise.

C. explains why marginal costs of production fall as additional units of output are produced.

D. explains why average productivity always rises.

The law of diminishing marginal returns states

A) that at some point adding more of a fixed input to a given amount of variable inputs will cause the marginal product of the variable input to decline.

B) that at some point adding more of a variable input to a given amount of a fixed input will cause the marginal product of the variable input to decline.

C) that in the presence of a fixed factor, at some point average product of labor starts to fall as more and more variable inputs are added.

D) average total costs of production initially fall and after some point starts to rise at a decreasing rate as output increases.

Diminishing marginal returns means that as you combine more units of a variable resource with a set of fixed resources:

a. the marginal physical product of the variable input decreases.

b. the average physical product of the fixed inputs increases at an increasing rate.

c. the marginal physical product of the variable input increases at a decreasing rate.

d. the total output decreases.

e. the marginal physical product of the variable input increases at a constant rate.

 

The law of eventually diminishing marginal returns: (Points : 1)

a. states that each and every increase in the amount of the variable factor employed in the production process will yield diminishing marginal returns.

c. the percentage change in output resulting from a given percentage change in the amount of the variable input X employed in the production process with Y
d. None of the above
