4. Suppose a monopolist faces two markets with the following
demand curves: Market 1: ?1(?1) = 400 − 2?1
Market 2: ?2(?2) = 1000 − 4?2
Let the marginal cost be $20 per unit in both markets.
If the monopolist can price discriminate, what should be ?1 and ?2 to maximize the monopolist’s profit?
1) D1=400-2p1
2p1=400-D1
p1=200-0.5D1
MR=200-D1
MR=MC
200-D1=20
D=200-20=180
P=200-0.5(180) = 110
2) D2=1000-4p2
4p2=1000-D2
p2=250-0.25D2
MR=250-0.5D2
MR=MC
250-0.5D2=20
250-20=0.5D2
D=230/0.5 = 460
P=250-0.25(460) = 135
