Exam 5: Competition and Monopoly: Virtues and Vices

One can find total profit by taking price minus average total cost (P-ATC) and then multiplying by output.

If economies of scale exist over the entire range of market output, we can describe this situation as

In long-run equilibrium, a perfectly competitive firm makes a(n)

Because of easy entry into and exit from a market, in long-run equilibrium perfectly competitive firms

If price is below minimum average variable cost, a profit-maximizing perfectly competitive firm will

A perfectly competitive firm's short-run supply curve is the segment of the marginal cost curve lying

A perfectly competitive firm maximizes profit per unit by producing and selling that output where marginal revenue equals marginal cost.

The development of e-mail and fax machines has reinforced the U.S. Postal Service's monopoly of first-class letter mail.

Which of the following is a good example example of a monopoly?

The graph of the total revenue schedule of a perfectly competitive firm is a downward-sloping curve because the firm sells additional units of output at a falling price.

A monopoly is a market structure characterized by a single supplier of a good or service for which there are many substitutes.

If a monopolist produces at that output level where marginal cost exceeds marginal revenue, to maximize profits the firm should

DeBeers, a producer of diamonds, is an example of a perfectly competitive firm.

Barriers to entry in a market include all of the following except

The U.S. Postal Service has a legal monopoly created by

A firm is producing output where MR=MC in a long-run situation. It is operating at the lowest possible average total cost, receiving the lowest possible price it can without going out of business, and earning no economic profit. Which market structure does it operate in?

Vouchers are based on the idea that parents should be able to choose the private or public schools they wish their children to attend.

Given identical cost conditions, a monopolist will charge a higher price and earn higher profits than would occur if the market had been perfectly competitive.
