[Q: 12-9754833] Consider a second-degree price discriminating monopolist faces an inverse demand curve given by P(Q) =96 - 2Q and has a cost function given by C(Q) = 1Q2 + 15Q. Suppose the monopolist uses two blocks in a declining-block pricing scheme. It charges a high price, P, , on the first Q, units (the first block) and a lower price, P2, on the next Q2 - Q1 units. Part A: Calculate the profit-maximizing values for P1. P2. Q1, and Q2 Q1: Q2: (Enter the quantities rounded to two decimal places and use the rounded value in the price calculation.) P1: P2: (Enter the prices rounded to two decimal places.) Part B: Now suppose that the economist that had estimated the cost function receives new data that suggests that a constant marginal cost function is more appropriate for this monopolist. The new cost function is estimated as C(Q) = 15Q. Calculate the profit-maximizing quantities using the updated cost function. Note: if you use the shortcut discussed in lecture, be careful not to round the competitive quantity. Q1: 13.5 Q2: 27 (Enter the quantities rounded to two decimal places.)
