Question:
(Cournot's Mineral Water Monopoly) Consider a monopolist who own an exclusive source of spring water, which produces water at 0 cost. The demand curve of the springwater is
q = 1pif p > p*
q =1pif 0 p p*
Your answer is conditioned on p*
- Suppose thatp*= 0.4. Suppose that the monopolist chooses quantityqto maximize the profit. Write down the profit maximization problem. Calculate the profit maximizing quantityqmand the market pricepmif the monopolist sets the quantity asqm.
- Calculate the realized social surplus (which is the sum of the pro- ducer surplus and the consumer surplus). Calculate and draw the social surplus as a function ofp*between 0 and 1.
- "A monopoly market is inefficient." Is this statement true, false or uncertain? Justify your answer. (Your point is based mostly on your justification.)
