Document Summary

Market structure: all features of a market that affect behaviour and performance of firms in the market. Firms have market power when they can influence the price of their product: the competitiveness of a market is determined by the degree to which individual firms lack market power. A market is said to have a competitive structure when its firms have little or no market power. The more market power firms have, the less competitive the market structure is. A perfectly competitive market occurs when each firm has zero marker power: firms in this market must accept the price set by the forces of market demand and supply. In perfectly competitive markets there is no need for individual firms to compete actively with one another. Competitive behaviour refers to the degree to which individual firms actively compete with one another for business: this occurs when firms have some real power over the market.

  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.

  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.

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

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

  2. total revenue will be unchanged if the price increases.
  3. total revenue will rise if the price increases.

  4. P = AVC.
  5. normal profits are zero.

In which of the following ways is a monopoly beneficial to an economy?

A. Monopoly profits give firms more reason to invest in the creation of new products through research and development.

B. Firms that are allowed monopoly profits search out innovative technologies that they can bring to market.

C. With natural monopolies, costs may be lower than those that would exist in competitive markets with many producers.

Which of the following is a difference between a perfectly competitive market and a monopoly?

B. The equilibrium price in a perfectly competitive market exceeds marginal revenue, while the equilibrium price in a monopoly equals marginal revenue.

C. The sellers in a perfectly competitive market are price-makers, while a seller in a monopoly market is a price-taker.

In the United States in 2011, there were 104 fatalities per 100,000 workers in the logging industry. This is the second-highest rate after the fisheries industry. Although the fatality rate in this industry is so high, many workers still choose to work as loggers.

What could explain this?

A. Workers choose these high-risk jobs because they are willing to bear an occupational risk to earn a higher wage.

B. Low-risk jobs are already taken, so workers must choose their next-best alternative, which in this case is logging.

C. Workers in these industries lack human capital and must choose to work as loggers.

D. Loggers must be indifferent between low-risk and high-risk jobs.

B. the price effect always dominates the quantity effect.

C. when the price effect dominates the quantity effect, total revenue decreases.

D. when the quantity effect dominates the price effect, total revenue decreases
