Answer #1

3. Suppose that a price-searcher monopolist had a total cost
function given by: TC= 20 + 2Q +0.25Q2.
The demand for the price searcher's product is given by:
QD= 100 -5P.
Calculate the price the monopolist will charge.

4. Suppose that a price-searcher monopolist had a total cost
function given by: TC= 20 + 2Q +0.25Q2.
The demand for the price searcher's product is given...

Consider a total cost function of TC = 0.5Q^2 +10Q + 20 and the
market demand function Q=70-p.
a What is the profit-maximizing output and price for the perfect
competition? Calculate its profit.
b What is the profit-maximizing output and price for the
monopolist? Calculate its profit.
c What is the profit-maximizing output and price for the
monopolist in the second market? Calculate its profit.

Consider a single-price monopolist. The monopolist's total cost
function is given by TC=2Q2. The demand curve for the
monopolist's outputs is given by Q=300-0.25P. The market will have
a deadweight loss of $____.

Suppose a representative perfectly competitive firm has the
following cost function: TC = 100 + 5Q2. The short-run
market demand and supply are given by: QD = 600 - 40P
and QS = 20P. How many firms are in the market in the
short-run?

12. A price-searcher firm wants to try a two-part tariff. The
firm's marginal cost is a constant $3 and it will
charge that as the per unit price. To complicate things, the firm
has two different groups of consumers. There are
50 consumers who have a demand function given by:
qD=18-0.5P. There are also
20 consumers who have a demand function given by:
qD=18-0.5P.
If the firm charges a fee that is too high, then it may lose all
of...

Question 8:
Suppose a monopolist faces a market demand of QD=800−PQD=800−P
and has a total cost function of TC(Q)=Q2TC(Q)=Q2.
What is the equilibrium price and quantity decided by the
monopolist?
What is the average cost at the equilibrium quantity?
How much profit does the monopolist make at the equilibrium
price and quantity?

Suppose the demand function is given by P = 100-0. 02Q , and
total cost is TC = 5Q . Find
the marginal revenue function, profit maximizing quantity,
profit maximizing price and draw
a fully labelled diagram. [5]

A perfectly competitive firm’s total cost function is given by:
TC = 200+2Q2 . You also know that the market demand
function for this product is: QD=100-P. How many
firms are in the market in the
long-run?
Select one:
a. N=10
b. N=8
c. N=6
d. None of the above

A perfectly competitive firm’s total cost function is given
by: TC = 400+4Q^2 . The minimum point of average total cost (ATC)
is reached at Q=10. You also know that the market demand function
for this product is: QD=100-P. How many firms are in the market in
the long-run? (Hint: first you need to find the price in the
long-run)
Select one:
a. N=6
b. N=4
c. N=2
d. None of the above

Suppose the market demand function is given by Q = 200 - 2p. The
monopolist has the following cost function TC = 100 + 0.5Q2 (MC =
0.5 + Q) (a) find profit maximizing p and Q for the monopolist (b)
suppose regulation was implemented and the regulator "coerced" the
monopolist to behave as "a competitive firm would(e.g., p=MC)".
Find this p and Q. (c) calculate the size of the (dead weight)
welfare loss triangle; (d) how much of this...
