In a perfectly competitive market, a firm's average revenue and cost functions are given as follows:

AR = α Q - β where α, β are constants and Q is the output

AC = α - β AR is the average revenue and AC is the average cost.

Q

On the basis of the functions given above, determine:

(i) Total revenue function.

(ii) Total cost function.

(iii) Total break-even output level.

(b) With the help of a well-illustrated diagram, explain how the long-run equilibrium of a perfect competitive model is achieved in an industry.

(c) Using an appropriate diagram, illustrate the profit maximizing output for a monopolistic firm.

(d) Explain three advantages of economies of scale to the firm.
