A monopoly sells in two separate markets such that goods sold in one market are never resold in the other. The demand curve for the product is given by P_A = 137 - 2Q_A in market A and P_B = 275 - 5Q_B in market B. The monopoly faces a constant marginal cost of production, MC = 5, and no fixed costs. The monopoly can charge different prices in the two markets.

(a). What is the profit-maximizing combination of quantities and prices for the monopoly?

(b). What if the monopolist couldn't price discriminate but noticed that type Aconsumers were coupon users. What would be the monopolist's profit-maximizing price?

(c). Suppose the price elasticity in market A is -1.08 and the price elasticity in market B is -0.80. What can the monopolist do in terms of output reallocation that will surely raise his profits?
