Q1 An identical firm in a competitive market has the following cost curve: C(q) = 2q2 + 20q + 32 where q is the number of products sold by each firm. Any entry or exit does not change the input costs in the market. The market demand for the product is given by Q = 280 – 2p, where Q is the total number of products sold in the market. (a) . What is the long-run market supply curve if there is free entry and exit in the market? What are the long-run market equilibrium price and output? What is the total number of firms in the market? (b). Suppose the government awards the operation permits only to 40 firms in the market. What are the individual firm’s supply curve and the market supply curve, respectively? What are the market equilibrium price and output? What is the amount of products sold by each firm? (c) . If a new firm wants to enter the market, it has to buy an operation permit from one of the existing firms.
