1. (a) Consider a perfectly competitive industry that produces a total output of 190 units in the long run. Suppose there are n identical firms in the market. Each firm then produces an amount 190/n. Further suppose that the total cost (TC) of a single firm in the market is TC = q2, where q is the amount the firm produces.

If the long run market price is P = 5, find the number of firms active (n) in the market.

(b) Consider a monopolist producer facing a demand curve and marginal revenue (MR) curve described by P = 100 - Q and MR = 100 - 2Q, respectively. The firm has a constant marginal cost (MC) of 10 and faces no fixed costs.

Find the equilibrium price and quantity if the monopolist wishes to maximise profit and draw a diagram to illustrate. Explain why the firm's monopoly power gives rise to a 'deadweight loss and indicate the area reflecting this deadweight loss in your diagram.

2. If GDP at current market prices was £994.3 billion in 2001, and £1,099.9 billion in 2003. The implicit GDP deflator was 100.0 in 2001 and 106.3 in 2003.
