3. Suppose that there are two individuals A and B. A's (inverse) demand is given by PA : 502QA and B's (inverse) demand is given by P3 = 70 4623. Suppose that the monopolist can rst degree price discriminate. a. b. What are the conditions that would have to be true in order for the monopolist to be able to rstdegree price discriminate in this market? (5 pts) Suppose the monopolist has costs given by C(Q) : IOQ. What is the optimal two-part tariff that he would charge each consumer? What is the optimal block pricing scheme for each of the consumers? Calculate total monopolist prots. (10 pts) Suppose now that the monopolist has costs given by C(Q) : 952. What is the optimal twopart tariff that he would charge each consumer? What is the optimal block pricing scheme for each of the consumers? Calculate total monopolist prots.(10 pts) Suppose that the monopolist has costs of C(Q) = 95:. Suppose that there is one individual of type A and three individuals of type B. What is the optimal block pricing scheme for each type of consumer? Calculate total monopolist prots. (10 pts)
