Document Summary

Firm: an institution that hires factors of production and organizes those factors to produce and sell goods and services. A firm"s goal is to maximize profit and everything in between is a means of reaching this goal (job satisfaction, high quality product, market share etc). Depreciation: the fall in the value of a firm"s capital. Determined by subtracting expenses and cogs from income to get net income. Accountants measures a firm"s profit to ensure they pay the correct amount of income. Economic profit: equal to the total revenue minus total cost (opportunity cost if. The value of the best alternative use of the resources that a firm uses in production (the value of real alternatives forgone), the sum of the cost of using resources: The firm could"ve bought diff resources to produce another good or service, the amount spent on these resources is an opp cost.

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.

A. A competitive firm

  1. can consider only its location in setting the price.
  2. must base its competitive price on product differentiation.
  3. has the ability to set its own price.
  4. must accept the price determined by the intersection of the market supply and demand curves.
  5. has no supply curve.

B. If a firm is making an economic profit, then

  2. there will be no change in the number of firms if the industry is perfectly competitive.
  3. the factors of production are being paid less than their opportunity costs.

  3. marginal revenue decreases when the price decreases.
  4. marginal revenue is equal to zero when the price is equal to zero

D. If, in the short run, a perfectly competitive firm is producing at a point where the total cost is greater than total revenue, then the firm should

  1. shut down because economic profits are negative.
  2. continue to produce as long as P > AVC.
  3. continue to produce because accounting profits are positive.
  4. set a higher price for its output.
  5. set a lower price for its output

E. For a perfectly competitive firm, the demand curve is

  1. the marginal revenue curve.
  2. perfectly inelastic.
  3. always equal to marginal cost.
  4. the same as the market demand curve

F. A firm in a(n) industry will have the most elastic demand curve

  1. monopolistic
  2. oligopolistic
  3. monopolistically competitive
  4. perfectly competitive

G. If the demand curve of a monopolist is in the inelastic range, then

  1. total revenue will fall if the price increases.
  2. total revenue will be unchanged if the price increases.
  3. total revenue will rise if the price increases.
  4. the total supply will increase by an equal amount if demand increases.
