  • How many suppliers are there in a monopoly market structure?
    There is only one supplier in a monopoly market structure.
  • What is a common example of a natural monopoly?
    Utilities, such as electricity companies, are common examples of natural monopolies.
  • Why do electricity companies often operate as monopolies?
    Electricity companies often operate as monopolies due to economies of scale, making it inefficient for multiple firms to serve the same area.
  • How do patents contribute to monopoly power in the prescription drug industry?
    Patents grant exclusive production rights to a company for a set period, limiting competition and giving the company monopoly power over the drug.
  • What is the main incentive for companies to research and develop new drugs under a monopoly?
    The main incentive is the protection provided by patents, which allows companies to profit exclusively from their research.
  • What are the barriers to entry like in a monopoly?
    Barriers to entry in a monopoly are high, making it difficult for new firms to enter the market.
  • List three sources of barriers to entry in a monopoly.
    Barriers can come from ownership of key resources, government protection (like patents), or natural monopolies due to economies of scale.
  • At what point does a monopoly maximize its profit?
    A monopoly maximizes profit where marginal revenue equals marginal cost.
  • Can monopolies earn long-run profits? Why or why not?
    Yes, monopolies can earn long-run profits because high barriers to entry prevent new competitors from entering the market.
  • How does the relationship between price and marginal revenue in a monopoly differ from perfect competition?
    In a monopoly, price is greater than marginal revenue, whereas in perfect competition, price equals marginal revenue.
  • Why is the marginal revenue curve below the demand curve in a monopoly?
    The marginal revenue curve is below the demand curve because the monopoly faces a downward-sloping demand, so it must lower the price to sell more units.
  • How does the price set by a monopoly compare to its marginal cost?
    The price set by a monopoly is above its marginal cost.
  • Where do monopoly profits come from in terms of price and cost?
    Monopoly profits come from setting the price above both marginal revenue and marginal cost.
  • What is a key difference between monopolies and perfectly competitive markets regarding entry barriers?
    Monopolies have high barriers to entry, while perfectly competitive markets have no significant barriers.
  • Why is it important to compare and contrast different market structures like monopoly?
    Comparing market structures helps understand how different conditions affect pricing, output, and profitability in various industries.
