Question
19-22. A (typical) firm in a perfectly competitive constant cost industry has total costs in the
short run given by:
TC 588 +8q+3q², 9 2
FC=396
where q is output per day and TC is the total cost per day in dollars. The firm has fixed costs of
$396 (already included in the TC equation above). The TC equation generates minimum average
costs of $92 (per unit) at q = 14. Questions 19 through 22 concern this firm and this industry.
19. You are told that in the short run there are 400 firms, including this one, in the industry, all
with the same cost curves described above. Suppose that the demand curve facing the industry is
given by the equation P=908.135Q where P is the price per unit and Q is the number of
units demanded per day. The equilibrium price in this industry in the short run is:
F) $105
A) $86
G) $108
B) $92
H) $110
A) $34
G) $71
C) $95
I) $111
20. This profit earned by each firm in this industry in this short run equilibrium is:
A) $69
B) $72
F) $99
G) $105
H) $110
21. This firm's shut down price is:
C) $53
I) $89
A) $86
G) $108
B) $47
H) $83
C) $87
I) $111
D) $98
J) none of the above
E) $101
C) $95
I) $111
D) $93
E) $96
J) none of the above
D) $56
E) $65
J) none of the above
22. We are now in a new short-run situation with 400 firms in the industry and the same cost
curves described at the beginning of this set of questions. Now, imagine that the industry
demand curve falls to P = 268 - .035Q. When the industry settles down into a new short-run
equilibrium, what will be the new equilibrium price?
B) $92
D) $98
F) $105
H) $110
F) $68
E) $101
J) none of the above
