Question

A monopolist has a marginal cost curve MC=Q and a home market demand P=30-Q. The monopolist can also sell in a foreign market at a price pf Pf=12. Find the quantity produced, quantity sold at home, and quantity sold in the foreign market, as well as the price charged at home.

Answer #1

P=30-Q

MR=30-2Q

Profit maximization for a monopolist which sells to segmented markets is where MR=MC

Across the markets, the marginal revenue for foreign = marginal revenue for home and the foreign marginal revenue function, MR=12 for additional units.

As MR=MC,Q=12

MC=MR for home:

30-2Q =12

Q(H) = 18/2 = 9 which is sold in the home market and the remaining will be sold to the foreign market

Q(F) = 12-9 = 3 units

Price charged at Home: = 30-quantity sold in home

=30-9 = 21

2. Say a monopolist sells in two separate markets, with demand
PA = 30 - 2Q (that is, the MRA = 30 – 4Q) and PB = 40 - Q (that is,
the MRB = 40 – 2Q), respectively. Marginal costs in both markets
are constant and equal to 10. What are the prices and quantities
that the monopolist would charge in each market to maximize profit.

1Suppose the firm is a monopolist. It faces a downward-sloping
demand curve, P(Q). If it also has non-negative marginal cost, will
it choose a quantity on the demand curve where the price elasticity
of demand is less than, greater than, or equal to -1? Explain.
2. Now, consider what will happen if a firm has exactly one
competitor in the market. Both firms have identical technologies
and cost structures (assuming a constant marginal cost may be
helpful), and each chooses...

A monopolist faces a demand curve given by P=40-Q, while its
marginal cost is given by MC=4+Q. Its profit maximizing output
is
a. 8 b. 9
c. 10 d.
11 e. 12
why is the answer (e)?

Q1. A monopolist has the following
demand function and marginal cost function P = 120 – Q and MC = 30
+ Q.
i. Derive the monopolist’s marginal revenue function.
ii. Calculate the output the monopolist should produce to
maximize its profit.
ii. (continuation)
iii. What price does the monopolist charge to maximize its
profit?
Now assume that the monopolist above split into two large firms
(Firm A and Firm B) with the same marginal cost as the
monopolist.
Let...

A monopolist faces the following demand curve, marginal
revenue curve, total cost curve and marginal cost curve for its
product: Q = 200 - 2P
MR = 100 - Q
TC = 5Q MC = 5
a. What is the profit maximizing level of output?
b. What is the profit maximizing price? c. How much profit
does the monopolist earn?

1. Consider a monopolist where the market demand curve
for the produce is given by P = 520 - 2Q. This monopolist has
marginal costs that can be expressed as MC = 100 + 2Q and total
costs that can be expressed as TC = 100Q + Q2 + 50. (Does not need
to be done. Only here for reference)
2. Suppose this monopolist from Problem #1 is regulated
(i.e. forced to behave like a perfect competition firm) and the...

A monopolist facing a market demand Q = 240 – 2p has the total
cost function TC(q) = q2. Draw carefully the relevant
graph with MC, MR, D curves and identify all relevant points,
intersections, intercepts.
(a) What is the monopolist’s profit maximizing quantity and
price?
(b) If the market is reorganized as perfectly competitive, what
should be the market price and quantity?
(c) Calculate the DWL associated with the monopoly in (a).
Now the government notices that the monopolist...

1. A monopolist faces a market demand curve given by Q = 53- P.
Its cost function is given by C = 5Q + 50, i.e. its MC =$5.
(a) Calculate the profit-maximizing price and quantity for this
monopolist. Also calculate its optimal profit.
(b) Suppose a second firm enters the market. Let q1
be the output of the first firm and q2 be the output of
the second. There is no change in market...

Consider an inverse demand curve for a monopolist: P = 200 -
0.05Q. The Marginal Cost function is MC = 50 + 0.2Q; Fixed Cost
(FC) =17,500.
What is the total cost (TC) function and the value of TC at pmax
Q? {Hint: Think “integration” of the MC function and then add fixed
cost (FC).}
Intercept or Q0 coefficient?
Q1 coefficient?
Q2 coefficient?

Suppose a monopolist faces market demand (Dm) of P(q) = a - bq

c. What is the monopolist's output at the price found in part
(b)?
d. What would be the market clearing price and quantity under
perfect competition
