Question

2. Suppose a monopoly firm faces inverse market demand curve p a - bQ. Its average total cost (ACc) and marginal cost (MC) both equal c where c >0. Assume that a>0, a> c, and b> 0. Assume that the firm maximizes its profit. Depict and identify the following five concepts graphically (a) (i)the firms profit-maximizing output QM (ii) the corresponding price PM, (ii) the socially optimal output Q* (iv) the firms supernormal profit and (v) the deadweight loss. (b) Explain what the firms deadweight loss means.

    ​​​​​​ i) A profit-maximising firm faces a downward-sloping demand curve for its output and has marginal costs that increase with output. Show, on a single diagram, how its profit maximisation decision can be represented both in terms of a feasible set optimisation and its marginal revenue and marginal cost. Why is there a deadweight loss in this case? (5) ii) Now assume the firm is a typical firm in a perfectly competitive market. Show the firm's optimal choice alongside the...
