DSE 2006 Question 29: Monopoly and price discrimination

A monopolist has two plants. In plant 111, the total cost function is c1(q1)=2q1c_1(q_1)=2q_1c1​(q1​)=2q1​, and in plant 222, the total cost function is c2(q2)=q22/2c_2(q_2)=q_2^2/2c2​(q2​)=q22​/2, where qqq represents the quantity of good produced. The demand faced by the monopolist is p=10−qp=10-qp=10−q, where q=q1+q2q=q_1+q_2q=q1​+q2​. How does the monopolist allocate its total production to serve the market?

Plain-text version

A monopolist has two plants. In plant 1, the total cost function is c₁(q₁)=2q₁, and in plant 2, the total cost function is c₂(q₂)=q₂²/2, where q represents the quantity of good produced. The demand faced by the monopolist is p=10-q, where q=q₁+q₂. How does the monopolist allocate its total production to serve the market? (A) q₁=6 and q₂=2 (B) q₁=2 and q₂=2 (C) q₁=4 and q₂=4 (D) q₁=4 and q₂=10/3

Also written as: A monopolist has two plants. In plant 1, the total cost function is c_1(q_1)=2q_1, and in plant 2, the total cost function is c_2(q_2)=q_2^2/2, where q represents the quantity of good produced. The demand faced by the monopolist is p=10-q, where q=q_1+q_2. How does the monopolist allocate its total production to serve the market?
