1. In long-run monopolistic competition,
a) all firms will produce an identical product
b) entry or exit will shift the demand curve until all firms
earn zero profit
c) firms might earn positive profits since strategic barriers
prevent new firms from entering
d) entry or exit will shift the supply curve until all firms
earn zero profit
e) firms may operate at a loss if the tax advantage are
sufficiently large

Consider a perfectly competitive market where all firms have
identical long-run marginal costs given by LRMC = 10. Furthermore,
suppose that the market demand curve is given by ? = 3000 −
50?.
a. Determine the long-run equilibrium quantity and price in this
market.
b. Determine the number of firms that operate in this market in the
long-run, assuming that a typical firm produces 25 units of
output.
Consider a firm with a short run Total Cost (TC) given by
TC=2000 + 1000Q - 40Q2 + Q3 . What is the
firms marginal cost? What is firm's shut down price?
Suppose a perfectly competitive firm's short-run total cost (TC)
is given by
TC = 200 + 4Q +
2Q2 where Q = output and 200 = fixed cost. As a result,
MC = 4 + 4Q.
Suppose the price of the firm's price is $24.
a.
How much should the firm produce in the short run to maximize
its profits?
b.
How large will the firm's short-run profits be? Remember Profit
= TR – TC.
c.
Should the...
All firms in a perfectly competitive industry have a long-run
total cost function of T C(Q) = 36Q − 4Q2 +
2Q3. The market demand curve is QD = 640 −
10P. The price of inputs is not affected by the industry
output.
a) Find the (long-run) average cost and marginal cost
curves.
b) What quantity will each firm produce in the long run?
c) What will be the market price in the long run?
d) What will be the...
all firms in a competitive industry have the following long-run
total cost curve: C(q) = q3 -10q2 +36q, where
q is the output of the firm
a. Find the price in the market and how many units each firm
will sell in the long run
b. If the market demand was Q = 10p-5, how much output will be
bought and sold in the market?
c. How many firms will exist in the long run?
d. What is their economic...
10. A perfectly competitive industry consists of many
identical firms, each with a long-run average total cost of LATC =
800 – 10Q + 0.1Q2 and long-run marginal cost of LMC = 800 – 20Q +
0.3Q2.
a. In long-run equilibrium, how much will each firm produce?
b. What is the long-run equilibrium price?
c. The industry's demand curve is QD = 40,000 – 70P. How many units
do consumers buy in long-run equilibrium? How many firms are in the...
In a particular market there are several hundred firms, all of
the firms produce an identical product, and it is easy to get in
and out of the market. At the current market equilibrium we observe
the following for a typical firm:
P=100
MC=100
ATC=75
Find the firm's marginal revenue
Is this firm maximizing profit? Explain how you can tell.
Find the firm's profit.
What two things must be true for a competitive market to be in
a long run...
In the short-run, in comparing the change in total variable cost
(TVC) and total cost (TC) associated with an additional unit of
output,
Answers:
a) the change in TC is greater than the change in TVC.
b) no generalization can be made because of change in TFC.
c) both are equal to MC.
d) the change in TVC is greater than the change in TC.
The short-run marginal product of a variable input has an
inverse relationship with the:

Long Run Cost
Derive a firm's total cost curve by using a firms isoquants and
isocost lines(note:be sure to show what is on the axis,and the
values for all points and curves-the correct labeling and spacing
of the things is very mportant)for the case where the firm has
a)constant return to scale
b)decreasing return to scale
c)increasing returns to scale
d)For decreasing return to scale ,from the total cost
curve,derive the correct long run marginal cost curve and long run...
