Document Summary

Market structure refers to all the features that may affect the behaviour and performance of the firms in a market. Firms have market power when they can influence the price of their product. A market is said to have competitive structure when its firms have little or no market power. The more market power the firms have, the less competitive is the market structure. The extreme form of competitive market structure occurs when each firm has zero market power. Perfectly competitive market structure or more simply, a perfectly competitive market: no need for individual firms to compete actively with one another because none has any power over the market. Competitive behaviour refers to the degree to which individual firms actively vie with one another for business. A firm decides how much output to produce in order to maximize its profits, it needs to know the demand for its product and also its costs of production.

  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.

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

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

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

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

  2. oligopolistic
  3. monopolistically competitive

  3. TR < TC.
  4. P = AVC.
  5. normal profits are zero.

1. When a firm is in a monopolistic competition market, if the firm sells 25 goods at a product price of $10, what is the marginal revenue per unit of the good sold if it sells 5 additional goods when it reduced the product price to $9.

A. $270 B. $20 C. $4 D. $2.50

2. An article in theĀ New York TimesĀ on technology in the 1990s, Michael Lewis wrote, 'The sad truth, for investors, seems to be that most of the benefits of new technologies are passed right through to consumers free of charge.' Lewis meant what when he said the benefits of new technology were "passed right through to consumers free of charge'?

A. In perfect competition, price equals the marginal cost of production. In this sense, consumers receive the new technology 'free of charge.'

B. In perfect competition, consumers place a value on the food equal to its marginal cost of production and since they are willing to pay the marginal valuation of the good, they are essentially receiving the new technology 'free of charge.'

C. In the long run, price equals the lowest possible average cost of production. In this sense, consumers receive the new technology 'free of charge.'

D. Firms in perfect competition are price takers. Since they cannot influence price, they cannot dictate who benefits from new technologies, even if the benefits of new technology being "passed right through to consumers free of charge.
