Exam 12: Firms in Perfectly Competitive Markets

Suppose Veronica sells teapots in the perfectly competitive teapot market.Her output per day and her costs are as follows: Suppose the current equilibrium price in the teapot market is $10.To maximize profit, how many teapots will Veronica produce, what price will she charge, and how much profit (or loss)will she make? Draw a graph to illustrate your answer.Your graph should include Veronica's demand, ATC, AVC, MC, and MR curves, the price she is charging, the quantity she is producing, and the area representing her profit (or loss).

The minimum point on the average variable cost curve is called

If a firm's total variable cost exceeds its total revenue, the firm should stop production by shutting down temporarily.

An individual seller in perfect competition will not sell at a price lower than the market price because

Which of the following describes a situation in which every good or service is produced up to the point where the last unit provides a marginal benefit to consumers equal to the marginal cost of producing it?

If, for a given output level, a perfectly competitive firm's price is less than its average variable cost, the firm

A perfectly competitive firm's marginal revenue curve is downward sloping.

When plasma television sets were first introduced prices were high and few firms were in the market.Later, economic profits attracted new firms and the price of plasma televisions fell.This example illustrates

New York Times writer Michael Lewis wrote that "The sad truth, for investors, seems to be that most of the benefits....are passed through to consumers free of charge." To which of the following did Lewis refer?

A perfectly competitive firm in long-run equilibrium produces output at the lowest possible average total cost.

Being a price taker, a perfectly competitive firm cannot receive a producer surplus in the short run.

Firms in perfectly competitive industries are unable to control the prices of the products they sell and earn a profit in the long run.Which of the following is one reason for this?
