Here's a list of the key knowledge points from the PDF:

  1. Market Structures Overview:

    • Four main types: perfect competition, monopoly, monopolistic competition, oligopoly
    • Classified by degree of competition, number of firms, entry freedom, product nature, demand curve

  2. Perfect Competition:

    • Assumptions: many buyers/sellers, homogeneous goods, price-takers, no entry barriers, perfect knowledge
    • Short-run equilibrium: P = MC = MR, possible supernormal profits
    • Long-run equilibrium: zero economic profits, P = MC = MR = AC
    • Short-run supply curve: portion of MC curve where MC > AVC
    • Long-run industry supply curve: can be increasing, constant, or decreasing cost
    • Advantages: efficient pricing, consumer sovereignty, production at minimum AC
    • Disadvantages: insufficient profits for investment, lack of product variety

  3. Monopoly:

    • Features: no close substitutes, barriers to entry
    • Reasons for entry barriers: economies of scale, natural monopoly, cost advantages, switching costs, network externalities, product differentiation, legal restrictions
    • Equilibrium: output where MC = MR, price given by demand curve
    • Demand curve: downward sloping, same as industry demand
    • Disadvantages: higher prices, lower output, lack of innovation incentive, potential inefficiencies
    • Advantages: economies of scale, profits for R&D and investment, innovation incentives

  4. Comparison between Perfect Competition and Monopoly:

    • Monopoly typically has higher prices and lower output
    • Monopoly can potentially have lower prices if it achieves significant economies of scale

  5. Other points:

    • Reminder about midterm test details
    • Learning experience feedback request
    • Short-run vs. long-run concepts in both market structures
    • Firm decision-making in loss situations (perfect competition)
