Both the perfectly competitive firm and the monopolistically competitive firm produce at the output where marginal revenue equals marginal cost (MR = MC) but only the perfectly competitive firm achieves allocative efficiency. Explain why this is the case

What will be an ideal response?


Unlike the perfectly competitive firm, the monopolistically competitive firm faces a downward sloping demand curve which means that the firm must lower its price to sell additional units of output. As a result, price will always be greater than marginal revenue (P > MR). By contrast, the perfectly competitive firm faces a horizontal demand curve and P = MR. The profit-maximizing rule, MR = MC, applies to all firms but because in perfect competition P = MR the rule can be written as P = MC. A firm achieves allocative efficiency if it charges a price equals to the MC of producing the last unit. This condition is satisfied at the profit-maximizing output for the perfectly competitive firm (since P = MC = MR) but will not hold for the profit maximizing output of monopolistically competitive firm for which P > MR = MC.
