Which of the following is true of a perfectly competitive firm in long-run equilibrium?

A) it will minimize its average total cost

B) the market demand curve is horizontal

C) the market supply curve is horizontal

D) marginal cost is minimized

E) it will charge a price above its marginal cost

Expert Solution

Ans) A) it will minimize its average total cost is the correct option. At profit maximisation, in perfect competition price is set equal to marginal cost. Since there are many buyers and sellers so firms are price takers and minimize the average total cost to increase the economic profit.

At long-run equilibrium in a perfectly competitive industry the typical firm is breaking even in an opportunity cost sense. T/F Perfectly competitive markets include firms that have significant market power, with one typically being the price leader. T/F In perfectly competitive markets, the individual firm’s demand curve is flat, while the market demand curve is typically sloping downward to the right. T/F When a firm maximizes profits, its price is derived from where marginal revenue crosses marginal cost (extend the...
