1-7 True or False

1) In the short run, a perfectly competitive firm can earn positive, zero, or negative profit depending on the market price of the firm's output.

2)In the model of the perfectly competitive firm, the firm's fixed costs are equal to its implicit costs of production.

3)Assume the market price is greater than average total cost at the perfectly competitive firm's profit-maximizing level of output. In this case, the firm is earning positive economic profits, which act as an incentive for new firms to enter the market.

4)Assume that at the current level of output, price equals marginal revenue, but is less than average total cost. So long as price is greater than average variable cost, the firm should continue to operate in the short run to minimize its losses.

5)The fact that a firm is a price-setter does not ensure it will make a positive economic profit in the short run and over time.

6)Barriers to entry serve to limit the number of firms that operate in a particular market and, as 11) such, reduce the amount of total profit earned in the market.

7)In the prisoner's dilemma game, each player's dominant strategy is also the Nash equilibrium.

14-17 Multiple Choice

14) Marginal revenue is equal to:
A) the change in P x Q due to a one unit change in output. B) the change in quantity divided by the change in price.

C) the change in price divided by the change in output. D) price, but only if the firm is a price searcher.

15) In order to maximize its profits, a price-taking firm should produce the level of output at which:

A) marginal revenue = marginal cost. B) total revenue = total cost.

C) variable revenue = variable cost. D) average revenue = average cost.

16) Assume that there is an improvement in the technology used by firms in a perfectly competitive industry that is initially in long-run equilibrium. In the short run this would cause:

A) cannot be determined with the information given. B) no change in the firm's economic profit.
C) a decrease in the firm's economic profit. D) an increase in the firm's economic profit.

17) Assume at the firm's profit-maximizing level of output P = AVC. In this case, the firm will be:

A) incurring an economic loss. B) earning a positive economic profit.

C) earning economic profit = 0. D) breaking even.

1. A monopoly firm is different from a competitive firm in that:
A. There are many substitutes for the monopolist's product, whereas there are no close substitutes for the competitive firm's product
B. The monopolist's demand curve is perfectly inelastic, whereas the competitive firm's demand curve is perfectly elastic
C. The monopolist is a price-maker, whereas the competitive firm is a price-taker
D. The monopolist always earns economic profits in the long run, whereas the competitive firm never earns economic profits in the long run

2. In the long run, an entrepreneur managing a perfectly competitive firm will earn:
A. Zero normal profits B. Economic profits and normal profits
C. The opportunity cost of operating the firm D. Negative economic profits

3. Refer to the graph above. The maximum possible total profit this monopolist can earn per day is:
A. $0 B. $1800 C. $2400 D. $4200

4. If marginal cost exceeds marginal revenue, the firm

A. is most likely to be at a profit-maximizing level of output.

B. should increase the level of production to maximize its profit.

C. must be experiencing losses.

D. may still be earning a profit.

5. A perfectly competitive firm maximizes profit by producing 500 units of output

46) If a profit-maximizing firm in a perfectly competitive market is making an economic profit, then it must be producing a level of output where A) marginal cost is greater than average total cost. B) marginal cost is greater than marginal revenue. C) price is greater than marginal revenue. D) price is greater than marginal cost. E) average total cost is greater than marginal cost.
