Analyze and then classify the statements as TRUE or
FALSE.
1. The average fixed cost always has a negative slope.
2. The average fixed cost is always lower than the average
total cost.
3. When there are constant returns to scale the slope of the
Long-run Average Cost curve is zero.
4. Marginal product and marginal cost have an inverse
relationship.
5. The marginal cost curve will intersect the average variable
cost curve at a lower value of quantity of output than it will
intersect the average total cost curve.
6. In the long-run all inputs of production are
variable.
7. In the short-run the average total cost curve is
fixed.
8. The average variable cost curve may fall (have a negative
slope) even when the marginal cost curve is rising.
9. The marginal cost curve intersects both the average
variable cost curve and the average total cost curve at each one’s
minimum value.
10. If MC > ATC, then ATC is rising.
11. If MC > AVC, then AVC is rising.
12. It is possible for the AVC to be increasing when the ATC
is decreasing.
13. It is possible for the MC curve to be rising while both
the AVC and ATC are falling.
MULTIPLE CHOICE:
14. Which of the following does NOT describe perfect
competition?
A. A large number of buyers and sellers with no single buyer
or seller having power to influence the price of the good being
sold.
B. Sellers are price takers.
C. The characteristics of the product vary significantly from
one producer to another.
D. Entry into the market requires a relatively low level of
capital investment and exit from the market is also relatively
easy.
E. None of the above.
TRUE or FALSE:
15. When a firm makes a normal profit its economic profit is
zero.
16. When a firm makes a normal profit its average total cost
is equal to average total revenue.
17. Given a firm is operating in a perfectly competitive
market and it is making a normal profit then we can conclude that
its marginal cost is equal to marginal revenue
