JNU SIS 2020 Question 3: Monopoly and price discrimination

Suppose that a monopolist faces two markets with the demand curves given by D1(p1)=100−p1D_1(p_1) = 100 - p_1D1​(p1​)=100−p1​ ; D2(p2)=100−2p2D_2(p_2) = 100 - 2p_2D2​(p2​)=100−2p2​. Let the marginal cost be constant and equal to 20. If the monopolist must charge the same price in each market, what price should it charge ?

Plain-text version

Suppose that a monopolist faces two markets with the demand curves given by D₁(p₁) = 100 - p₁; D₂(p₂) = 100 - 2p₂. Let the marginal cost be constant and equal to 20. If the monopolist must charge the same price in each market, what price should it charge? (A) p* = (431/3) (B) p* = 50 (C) p* = 60 (D) None of the above

Also written as: Suppose that a monopolist faces two markets with the demand curves given by D_1(p_1) = 100 - p_1; D_2(p_2) = 100 - 2p_2. Let the marginal cost be constant and equal to 20. If the monopolist must charge the same price in each market, what price should it charge?
