Solution
b. Profit maximization in monopoly situation
Monopolist is a price Maker. He will determine the quantity of output that will maximize revenue. The monopolist faces a downward sloping demand curve because he can sell more if he lowers the price. The profit maximizing price and output is where marginal revenue equals marginal cost, then it is extended to the market demand curve to determine what market price corresponds to that quantity.
The monopoly profit equals (P-ATC) x Q.
P=$22
ATC=$12
Q= where MR=MC=8
Profit =($22-$12) x 8=$80.
C. Socially optimal outcome
The socially optimal quantity is at the intersection of MC and demand curve.
Q= MC=D= 12
Price at MC=D=$18
ATC=$13
Profit ($18-$13) x 12=$60
D. Fair return outcome
The fair return outcome is at the intersection of ATC and demand curve
Q= ATC=Demand curve= 15
Price at ATC=D=$15
ATC=$15
Profit=($15-$15)x 15=$0
Since P=ATC, the monopolist makes zero economic profit.
