A monopolist sells in two geographically divided markets, the East and the West. Marginal cost is constant at $50 in both markets. Demand and marginal revenue in each market are as follows:

QE = 900 - 2Pe
MRe = 450 - QE
QW = 700 - PW
MRw = 700 - 2Qw

a. Find the profit-maximizing price and quantity in each market.
b. In which market is demand more elastic?

Solution Preview

a. Find the profit-maximizing price and quantity in each market.

Marginal Cost=MC=$50

Market : East
MRe=450-QE
Put MRe=MC
450-QE=50
QE=400

QE=900-2Pe
Put QE=400
400=900-2Pe
2Pe=500
Pe=250

Profit Maximizing price in East=$250
Profit Maximizing ...

Solution Summary

Solution depicts the steps to find out the optimal price and output combinations in two different markets.

"How high should a monopoly set its prices in order to maximize profits? When you post a response to this question, place it in the context of one of the following examples:
A geographically isolated gas station.
A concert on campus.
Soft drinks at a sporting event.
A prescription drug. "

Illustrate and explain how the profit maximizing level of output is determined when markets are characterized by imperfect competition. Describe how markets in perfect competition differ from markets that are imperfectly competitive. What role does the firm have in determining market price under each condition?

1. A profit-maximizing firm operating in a perfectly competitive market can sell products for $100 per unit. The firm has a cost function represented by:
C(Q) = 1000- 160Q + 10QSqr(10 q squared) . The market demand function for this product is Qd = 500 - 3P.
a.What is the profit maximizing output for this company?
b.Wh

Assume a monopolist with the following:
Qd =100-10p
TC = 1 + 2Q
Find the following:
a) Price at profit maximizing output
b) Profit maximizing output
c) Total Revenue at profit maximizing output
d) Total Cost at profit maximizing output
e)Profit

In a monopoly with a 50-50 chance of a demand curve of P=20-Q or P=40-Q and MC=Q, what is the profit maximizing price. Please show the steps to find either $5, 10, 15, or 20.

Assume a monopolist with the following demand and cost relationships.
Q = 400 - 20P
TC = 10 + 5Q + Q^2 (Where "^" means "to the power of")
Calculate the following:
Profit maximizing price
Profit maximizing quantity
TR, TC, and Profit at profit maximizing Q and P.

A monopolist produces a single homogeneous good, which she sells in two distinct markets
between which price discrimination is possible. Her total cost function is:
TC = 1/3 Q3 - 7.5Q2 + 370Q + 100
The demand curves in the two markets are given by:
q1 = 80 - 0.2p1 and q2= Ap2-5
The monopolist achieves a pro

Suppose a typical consumer's inverse demand function for bottled water at a resort area where one firm owns all the rights to a local spring is given by P = 15 - 3Q. The marginal cost for gathering and bottling the water is $3/gal. Find the optimal number of bottles to package together for sale and the profit-maximizing pric

Consolidated Salt Company sells table salt to both retail grocery chains and commercial users (e.g., bakeries, snack food makers, etc.). The demand function for each of these markets is:
Retail grocery chains: P1 = 180 - 8Q1
Commercial users: P2 = 100 - 4Q2
where P1 and P2 are the prices charged and Q1 and Q2 are the quan
