One of the defining characteristics of a perfectly competitive market is:

  1. a small number of sellers.
  2. a large number of buyers and a small number of sellers.
  3. a similar product.
  4. significant advertising by firms to promote their products.

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

  1. the factors of production are being paid their opportunity costs.
  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.
  4. the factors of production are being paid more than their opportunity costs.
  5. the firm will exit the industry

C. Along a downward-sloping monopoly demand curve,

  1. marginal revenue is greater than price.
  2. the elasticity of demand is constant.
  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.
  5. the price will be unchanged if total revenue increases

H. Monopolistic competition and oligopoly are examples of

  1. monopoly.
  2. perfect competition.
  3. theories of consumer behavior.
  4. imperfect competition.
  5. the extreme cases on the market structure continuum

I. Under which market structure do firms face the flattest (most elastic) demand curve?

  1. perfect competition
  2. monopolistic competition
  3. oligopoly
  4. monopoly

J. At the point of long-run equilibrium for a perfectly competitive firm,

  1. economic profits are zero.
  2. TR > TC.
  3. TR < TC.
  4. P = AVC.
  5. normal profits are zero.

Which of the following is not necessarily a characteristic of perfect competition? (Points: 1)

low prices
a large number of buyers and sellers
a homogeneous product
perfect information

2. In the short run, a perfectly competitive ball bearing manufacturer will continue to produce at a loss if (Points :1)
it is covering all of its variable cost plus part of its fixed cost

it is covering all of its fixed cost
variable cost is less than the fixed cost
fixed cost is zero

3. The golden rule of profit maximization states that any firm maximizes profit by producing where (Points :
marginal revenue equals marginal cost
demand is unit elastic, and total revenue is the greatest
price equals marginal revenue
price equals marginal cost


4. Which of the characteristics of perfect competition assures that economic profit will be zero in the long run? (Points: 1)
There are easy entry and exit in the market.
Each firm is a price taker.
Each firm has access to perfect information.
Each firm is small relative to the market.


5. A constant-cost industry is distinguished by the fact that(Points: 1)
firms' short-run average total costs are horizontal
firms' short-run marginal cost curves are horizontal
the long-run industry supply curve is perfectly elastic
the short-run industry supply curve is perfectly elastic


6. Commodity products are (Points: 1)
pasteurized
bland
perceived by consumers to be identical
made by one manufacturer


7. In a perfectly competitive industry we are likely to find(Points: 1)
firms producing a wide variety of products
barriers to entry
no profit possible in the short run
firms that do not advertise


8. Perfectly competitive firms are price takers because (Points :1)
all small firms must take the price set by the largest firm in the market
firms take the price that government determines is a "fair" price
each firm is small and goods are perfect substitutes for one another
free entry and exit in the short run creates a constant market price in the long run


9. In perfect competition, if one firm raises its price, (Points :1)
others will follow
that firm will increase its revenues
that firm will lose revenues because other firms will not follow
all consumers will be adversely affected


10. Suppose, at its present rate of output, a perfectly competitive firm's marginal revenue exceeds both its marginal cost and its average variable cost. To maximize profit, the firm should (Points: 1)
lower the price
raise the price
increase output
reduce output
